Printing characters using Nested loops

today while I was coding I ran into a problem I couldn't figure out.
So my task is to print a chosen amount of characters, the catch is I need to also specify how much characters are in one line.
For example:
I need to print 24 characters '*'
I select the character.
Select how many: 24.
Select how many character per each line: 7.
Result should look something like this:
*******
*******
*******
***
I have to strictly use nested loops!
Code example:
static void Main(string[] args)
{
char character;
int charAmount;
int charAmountInLine;
Console.WriteLine("Select character");
character = char.Parse(Console.ReadLine());
Console.WriteLine("Select total amount of characters");
charAmount = int.Parse(Console.ReadLine());
Console.WriteLine("Select amount of characters in each line");
charAmountInLine = int.Parse(Console.ReadLine());
Console.WriteLine("");
for (int i = 0; i < charAmount; i++)
{
for(int j = 0; j < charAmountInLine; j++)
{
}
}
}
}
}

In this program, you need to identify:
Number of lines that print full characters in a line (row)
Print the remaining characters (remainder)
Concept:
Iterate each row (first loop).
Print character(s) in a line (nested loop in first loop).
Once print character(s) in a line is completed, print the new row and repeat Step 1 to Step 3 to print full characters in a line if any.
Print the remaining character in a line (second loop).
int row = amount / characterPerLine;
int remainder = amount % characterPerLine;
for (int i = 0; i < row; i++)
{
for (int j = 0; j < characterPerLine; j++)
{
Console.Write(character);
}
Console.WriteLine();
}
// Print remaining character
for (int i = 0; i < remainder; i++)
{
Console.Write(character);
}
Demo # .Net Fiddle

First of all count number of rows for outer loop
int numberOfRows = (int)Math.Ceiling((double)charAmount / charAmountInLine);
for (int i = 0; i < numberOfRows; i++)
{
charAmount -= charAmountInLine;
charAmountInLine = charAmount> charAmountInLine? charAmountInLine: charAmount;
for (int j = 0; j < charAmountInLine; j++)
{
Console.Write(character);
}
Console.WriteLine("");
}

Try this one:
int row = (int)Math.Ceiling((double)charAmount/(double)charAmountInLine);
int column = 0;
int temp = 0;
for (int i = 1; i <= row; i++)
{
temp = (i * charAmountInLine);
column = temp < charAmount ? charAmountInLine : temp - charAmount;
for(int j = 0; j < column; j++)
{
Console.Write(character);
}
Console.WriteLine();
}

Text bombardment

this is the program I'm trying to write:
Write a program that reads a text and line width from the console. The program should distribute the text so that it fits in a table with a specific line width. Each cell should contain only 1 character. It should then read a line with numbers, holding the columns that should be bombarded.
My code looks like this:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace _04.Text_Bombardment
{
class Program
{
static void Main(string[] args)
{
var sentence = Console.ReadLine();
var bombing = int.Parse(Console.ReadLine());
var selected = Console.ReadLine().Split(' ').Select(int.Parse).ToArray();
Dictionary<int, bool> bombDict = new Dictionary<int, bool>();
var newSentence = sentence + new string(' ', bombing - sentence.Length % bombing); // whole row minus words left
for (int i = 0; i < selected.Length; i++)
{
bombDict.Add(selected[i], true);
}
var rows = newSentence.Length / bombing;
var cols = bombing;
var count = 0;
var arrSent = newSentence.ToCharArray();
for (int i = 0; i < rows; i++)
{
for (int j = 0; j < cols; j++)
{
if (bombDict.ContainsKey(j) && bombDict[j] == true && arrSent[count] != ' ')
{
arrSent[count] = ' ';
try
{
if (arrSent[count + bombing] == ' ')
{
bombDict[j] = false;
}
else
{
bombDict[j] = true;
}
}
catch (IndexOutOfRangeException)
{
continue;
}
}
count++;
}
}
var finalSent = string.Join("", arrSent).TrimEnd();
Console.WriteLine(finalSent);
}
}
}
And it breaks on this sentence:
Vazov received his elementary education in hisnative town of Sopoandat Plovdiv. The son of a conservative, well-to-do merchant.
20
1 6 17 2 5 0 15
Current Output:
ov eceived i e en ry educa i n hi ative to n of opo dat Plov iv. T e s of a co serva ive well-to- o mer ha t.
Intended Output:
ov eceived i e en ry educa i n hi ative to n of opo dat Plov iv. T e s of a co serva ive well-to- o mer han .
Soo it only doesn't work on the end.
Can someone help me?
Any suggestions?
Additional notes:
For example, we read the text "Well this problem is gonna be a ride." and line width 10. We distribute the text among 4 rows with 10 columns. We read the numbers "1 3 7 9" and drop bombs on those columns in the table.
The bombs destroy the character they fall on + all the neighbouring characters below it.
Note: Empty spaces below destroyed characters stop the bombs (see column 7).
Finally, we print the bombarded text on the console: "W l th s p o lem i o na be a r de."
Note: The empty cells in the table after the text should NOT be printed.

Your solution is very difficult to understand, keep it simple give names to the variables that you can understand easily.
I modified your code, hope it helps you:
static void Main()
{
string sentence = "Well this problem is gonna be a ride.";
int numberOfColumns = int.Parse("10");
List<int> bombs = "1 3 7 9".Split(' ').Select(int.Parse).ToList();
// we need to convert to decimal, otherwise C# will ignore decimal part.
//example: 127/20 = 6.35, so we need 7 rows. if we don't convert to decimal we have 6
// the Ceiling says, always round up. so even 6.1 will be rounded to 7
int numberOfRows = (int)Math.Ceiling(sentence.Length / Convert.ToDecimal(numberOfColumns));
char[,] array = new char[numberOfRows, numberOfColumns];
int sentencePointer = 0;
for (int rowIndex = 0; rowIndex < numberOfRows; rowIndex++)
{
for (int colIndex = 0; colIndex < numberOfColumns; colIndex++)
{
// if you want to print the grid with the full text, just comment the 3 lines below,
//and keep only "array[rowIndex, colIndex] = sentence[sentencePointer];"
if (bombs.Contains(colIndex))
{
if (sentence[sentencePointer] == ' ') // bomb is deactivated
{
bombs.Remove(colIndex);
array[rowIndex, colIndex] = sentence[sentencePointer];
}
else
array[rowIndex, colIndex] = '*'; // * represents a bomb
}
else
array[rowIndex, colIndex] = sentence[sentencePointer];
sentencePointer++; // move next character
if (sentencePointer >= sentence.Length)
break; // we reach the end of the sentence.
}
}
PrintGrid(array, numberOfRows, numberOfColumns);
// just give some space to print the final sentence
Console.WriteLine("");
Console.WriteLine("");
Console.WriteLine("");
for (int rowIndex = 0; rowIndex < numberOfRows; rowIndex++)
{
for (int colIndex = 0; colIndex < numberOfColumns; colIndex++)
{
Console.Write(array[rowIndex, colIndex]);
}
}
Console.ReadKey();
}
private static void PrintGrid(char[,] array, int numberOfRows, int numberOfColumns)
{
Console.WriteLine(new string('-', numberOfColumns * 2));
for (int rowIndex = 0; rowIndex < numberOfRows; rowIndex++)
{
Console.Write("|");
for (int colIndex = 0; colIndex < numberOfColumns; colIndex++)
{
Console.Write(array[rowIndex, colIndex]);
Console.Write("|");
}
Console.WriteLine("");
}
}

Somewhat more elegant solution.
private static IEnumerable<char> Bomb(IEnumerable<char> text, IEnumerable<int> indexes, int length)
{
var indexArray = new List<int>(indexes);
var used = new object[length];
return text.Select(
(c, index) =>
{
if (c != ' ' && indexArray.Contains(index % length))
{
used[index % length] = new object();
return '\0';
}
if (c == ' ' && used[index % length] != null)
{
indexArray.Remove(index % length);
}
return c;
});
}

How to print star like below in console application? I/p 5 O/p like = 1 212 32123 4321234 543212345 [duplicate]

My question is how to make a pyramid using * and 'space' in C#? The output will be like this.

We only need to use "for loop" for this program. I only know how to make this one.

I made a program like this:
static void Main(string[]args)
{
int i=o;
int j=o;
for(i=5;1>=1;i--)
for(j=1;j<=5;j++)
{
Console.Write("*");
}
Console.WriteLine(" ");
}
I'm confused when it comes to pyramid because it includes spaces. Thanks for your help!

think about how you'd print the pyramid manually.
suppose 5 levels deep.
1st line: 4 spaces, 1 star,
2nd line: 3 spaces, star, space, star
3rd line: 2 spaces, star space star space star
etc.
doesn't matter whether you print spaces after the last star or not - won't make a difference to how it looks.
what do we see?
if we have a total of X levels
line 1: (x-1) spaces, (star space)
line 2: (x-2) spaces, (star space) twice
line 3: (x-3) spaces, (star space) three times
line 4: (x-4) spaces, (star space) four times
that's the pattern. I'll leave the coding to you.

using System;
class Program
{
static void Main(string[] args)
{
int num, i, j, k;
Console.Write("enter the level:");
num=Convert.ToInt32(Console.ReadLine());
for (i = 1; i <= num; i++)
{
for (j = 1; j < num-i+1; j++)
{
Console.Write(" ");
}
for (k = 1; k <= i; k++)
{
Console.Write(i);
Console.Write(" ");
}
Console.WriteLine();
}
}
}

Your problem is spaces, therefore I suggest you think about the spaces. Tell me this: how many spaces are on each row to the left of the first star? You'll likely be able to solve your own problem if you think about this.

Try to think of it as a grid or a matrix and see where you want the '*' in each row and how it relates to your loop index.

sorry I missed this was homework... will give a strategy ... instead
it helps if you do it in notepad and think about what you are doing... you will start to understand the relationship between the line you are on and the spaces and what not...

Post my answer after 3 hours. I think now you have almost finished it under #iluxa's advice?
int height = 20;
for (int level = 1; level <= height; level++)
{
string text = string.Join(" ", Enumerable.Repeat("*", level));
Console.WriteLine(text.PadLeft(height - level + text.Length));
}
I used some build-in methods e.g. Enumerable.Repeat and String.PadLeft, not the pure C-language way. The purpose is that I want to tell you since you have chosen C# as the programming language(not C/Java/etc), you should resolve problems in the C# way.

using System;
using System.Collections.Generic;

Console.WriteLine("enter a number:");
int n = Convert.ToInt32(Console.ReadLine());
for (int i = 1; i <= n; i++)
{
for (int x = i; x <= n; x++)
{
Console.Write(" ");
}
for (int j = 1; j <= i; j++)
{
Console.Write("*"+" ");
}
Console.WriteLine();
}
Console.ReadLine();
}
}
}

Try this and follow this same logic in c, c++, php, java
using System;
class pyramid {
static void Main() {
/** Pyramid stars Looking down
Comment this if u need only a upside pyramid **/
int row, i, j;
// Total number of rows
// You can get this as users input
//row = Int32.Parse(Console.ReadLine());
row = 5;
// To print odd number count stars use a temp variable
int temp;
temp = row;
// Number of rows to print
// The number of row here is 'row'
// You can change this as users input
for ( j = 1 ; j <= row ; j++ ) {
// Printing odd numbers of stars to get
// Number of stars that you want to print with respect to the value of "i"?
for ( i = 1 ; i <= 2*temp - 1 ; i++ )
Console.Write("*");
// New line after printing a row
Console.Write("\n");
for ( i = 1 ; i <= j ; i++ )
Console.Write(" ");
// Reduce temp value to reduce stars count
temp--;
}
/** Pyramid stars Looking up
Comment this if u need only a downside pyramid **/
int rowx, k, l;
// Total number of rows
// You can get this as users input
// rowx = Int32.Parse(Console.ReadLine());
rowx = 5;
// To print odd number count stars use a temp variable
int tempx;
tempx = rowx;
//Remove this if u use
Console.Write("\n");
// Number of rows to print
// The number of row here is 'rowx'
for ( l = 1 ; l <= rowx ; l++ ) {
// Leaving spaces with respect to row
for ( k = 1 ; k < tempx ; k++ )
Console.Write(" ");
// Reduce tempx value to reduce space(" ") count
tempx--;
// Printing stars
for ( k = 1 ; k <= 2*l - 1 ; k++ )
Console.Write("*");
// New line after printing a row
Console.Write("\n");
}
}
}

The following code might help:
public static void print(int no)
{
for (int i = 1; i <= no; i++)
{
for (int j = i; j <= no; j++)
{
Console.Write(" ");
}
for (int k = 1; k < i * 2; k++)
{
if(k % 2 != 0)
{
Console.Write("*");
}
else
{
Console.Write(" ");
}
}
Console.WriteLine();
}
Console.ReadLine();
}

Here I have created a number pyramid:
using System;
public class Program
{
public static void Main()
{
Console.WriteLine("This is a number pyramid....");
var rows = 5;
for(int i = 1; i <= rows; i++)
{
for(int lsc = (-rows); lsc <= -2; lsc ++)
{
if(lsc < (-1)*i)
{
//write left sided blank spaces
Console.Write(" ");
}
else
{
//write left sided numbers
Console.Write(-1*(lsc));
}
}
for(int rsc = 1; rsc <= rows; rsc++)
{
//write right sided blank spaces
Console.Write(" ");
}
else
{
//Write sided numbers
Console.Write(rsc);
}
}
Console.WriteLine();
}
}
}
I have described here https://utpalkumardas.wordpress.com/2018/04/20/draw-number-pyramid
Out put is:
The is a number pyramid....

I know it's javascript but might help
let n = 6;
for (let i = 1; i <= n; i++) {
let spaces = n-i;
let str = '';
for (let j=0; j < spaces; j++) {
str+=' ';
}
for (let j=0; j < i; j++) {
str+='* ';
}
console.log(str)
}

I have found two approaches:
//1st approach
int n = 6;
for (int i = 0; i < n; i++)
{
// need to print spaces
for (int j = 0; j < n - i - 1; j++)
{
Console.Write(" ");
}
// need to print * with one space
for (int k = 0; k <= i; k++)
{
Console.Write("* ");
}
Console.WriteLine();
}
// 2nd Approach
int rows = 6;
int temp = 0;
bool toggle = false;
for (int j = 0; j < rows; j++)
{
int counter = 0;
for (int i = 0; i < 2 * rows - 1; i++)
{
if (i < rows - temp - 1)
{
Console.Write(" ");
}
else
{
if (counter <= j + temp)
{
if (!toggle)
{
Console.Write("*");
toggle = true;
}
else
{
Console.Write(" ");
toggle = false;
}
}
counter++;
}
}
Console.WriteLine();
temp++;
toggle = false;
}

How do I print the output in one row below another?

For example I am trying to print the output in following way:
disk: 1 2 3 4 5
move: 1 3 7 15 31
How can I do that, can someone help me out please?
{
class Program
{
static void Main(string[] args)
{
int n = 2;
for (int j = 1; j <= 5; j++)
Console.WriteLine("disk: {0}", j);
for (int i = 1; i <= 5; i++)
Console.WriteLine("moves: {2:N0}",
n, i,(long)Math.Pow(n, i) - 1);
}
}
}

Console.WriteLine will, as it sounds, write a new line each time. If you don't want that behavior, use Console.Write.
Console.Write("Disk:");
for (int j = 1; j <= 5; j++)
Console.Write(" {0}", j);
Console.WriteLine();
Console.Write("Moves:");
for (int i = 1; i <= 5; i++)
Console.Write(" {2:N0}", (long)Math.Pow(n, i) - 1);
Console.WriteLine();

Use the string.PadLeft() method to justify your text. Of course you can replace the magic numbers with a constant value. This gives you the advantage of not having to count spaces, and automatically adds the right amount of spaces to bring the string up to the desired length.
Note that you can also get rid of the format insertion (i.e. no more curly braces).
static void Main(string[] args)
{
int power = 2;
Console.Write("disk:".PadLeft(8));
for (int j = 1; j <= 5; j++)
Console.Write(j.ToString().PadLeft(5));
Console.WriteLine();
Console.Write("moves:".PadLeft(8));
for (int i = 1; i <= 5; i++)
Console.Write(((long)Math.Pow(power, i) - 1).ToString().PadLeft(5));
Console.WriteLine();
Console.ReadLine();
}
This is the result:

You can use Console.Write and it wont print a carriage return.
However you dont need a for loop in this case. Just use Enumerable.Range
var n = 2;
var disks = Enumerable.Range(1, 5).ToList();
var moves = Enumerable.Range(1, 5).Select(i => (long) Math.Pow(n, i) - 1);
Console.WriteLine("disk: {0}", string.Join(" ", disks));
Console.WriteLine("moves: {0:N0}", string.Join(" ", moves));
Results:
disk: 1 2 3 4 5
moves: 1 3 7 15 31

how can I draw a triangle of asterisks using the while statement?

here is the (not working code) and it should print the shape below but its not :
static void Main(string[] args)
{
int i = 1;
int k = 5;
int h = 1;
while (i <= 5)
{
Console.WriteLine("");
while (k > i)
{
Console.Write(" ");
k--;
}
while (h <= i)
{
Console.Write("**");
h++;
}
i++;
}
Console.ReadLine();
}
but when I try to do the same using the while statement the shape gets totally messed up.
any help ?

You have to declare k and h within the loop:
static void Main(string[] args)
{
int i = 1;
while (i <= 5)
{
int k = 5;
int h = 1;
Console.WriteLine("");
while (k > i)
{
Console.Write(" ");
k--;
}
while (h <= i)
{
Console.Write("**");
h++;
}
i++;
}
Console.ReadLine();
}
With your current solution, after first outer loop iteration, inner loops do nothing.

int NumberOfLines = 5;
int count = 1;
while (NumberOfLines-- != 0)
{
int c = count;
while (c-- != 0)
{
Console.Write("*");
}
Console.WriteLine();
count = count + 2;
}
That's it, simplest implementation.

The problem is that i, k and h are initialised before the outermost loop is entered. Within the outer loop k and h are altered by the inner loops. On the second execution of the outer loop k and h have the same values as were left after running the inner loops previously. As i increments in the outer loop, the k loop will not be entered and the h loop will only run once.
Think about what values h and k should have inside the outermost loop on the second execution.

I'll not solve for you just will give you hint only:
Use 3 loop statements
1. for line change
2. for spaces (reverse loop)
3. for printing * (odd series in this case) i.e. 2n-1
check in third while statement h <= 2*i - 1;
and print only one * in place of **

Actually I've done this via 'for' loop, z is height and x is equal to length of side.
Isosceles triangle (x>z):
public void Print(int x, int z)
{
var peakStart = x;
var peakEnd = x;
for (int i = 0; i < z; i++)
{
for (int j = 0; j < 2 * x + 1; j++)
{
if (peakStart < 1.5 * x && j >= peakStart && j <= peakEnd)
Console.Write("*");
else
Console.Write(" ");
}
peakStart--;
peakEnd++;
Console.WriteLine("");
}
}
