So i have to sent a message from a Sender to a Destination(Shown in main class) by specifing how many letters i wanna sent (the size variable).When the laters left are less than letters i wanna sent,it automaticaly sent how many i have left,and after the algorithm stops;
The problem is when the message i supossely sent is 9 characters long,and when i wanna sent 6 characters and another 3 it throws me an error (System.IndexOutOfRangeException: 'Index was outside the bounds of the array.'
)

Honestly I can see you try hard (too hard) to handle the limit case of the last block that can just not meet the expect size.
Since you do this in dotnet C#, and depending on the version you will see you have many different options....
Especially to create a batch of x out of a simple sequence....
here is a homemade version of things you will find for free in libraries like moreLinq and probably in latest Linq lib..
using System;
using System.Collections.Generic;
using System.Threading.Tasks;
using System.Linq;
public static class LinqExtensions
{
public static IEnumerable<IEnumerable<T>> Batch<T>(this IEnumerable<T> source, int size)
{
return source
.Select( (c, i) => (c, index : i))
.Aggregate(
new List<List<T>>(),
(res, c) =>
{
if (c.index % size == 0)
res.Add(new List<T> { c.c });
else
res.Last().Add(c.c);
return res;
});
}
}
public class Program
{
public static void Main(string[] args)
{
var test = "xxxxxxxxxxx".AsEnumerable();
var blocks = test
.Batch(3)
.Select(b=> new string(b.ToArray()));
blocks.ToList().ForEach(System.Console.WriteLine);

I try to calculate the total collective age of my passengers in calc_total_age() this works before I add a passenger and writes out "0". However when I add a passenger I get NullReferenceException, I have tried different things but I just can't wrap my head around what I'm doing. I need a little shove in the right direction and maybe and explanation of what the he** I am doing and I don't know what my GetAge() does either really I have tried to call it but it doesn't seem to work.
This is all my code:
using System;
using System.Linq;
using System.Text;
using System.Collections.Generic;
using System.Threading.Tasks;
class Program {
public static void Main (string[] args) {
//Console.Clear();
Console.WriteLine("Hi, welcome to the Buss-Simulator!");

info_passengers = new Passenger[25];
string [] menu = new string[]{"1. Pick up passenger.", "2. Show who's on the bus.", "3. Calculate total age of passengers"};
int MenuSelect = 0;
while (true)
{
Console.Clear();
Console.WriteLine("What do you want to do?");
Console.WriteLine();
Console.CursorVisible = false;
if (MenuSelect == 0)
{
Console.WriteLine(menu[0] + " ⭅");
Console.WriteLine(menu[1]);
Console.WriteLine(menu[2]);

if(keyPressed.Key == ConsoleKey.DownArrow && MenuSelect != menu.Length -1)
{

}

Array.Resize(ref info_passengers, info_passengers.Length + 1);
info_passengers[info_passengers.Length - 1] = passenger;
}
catch (Exception e)
{
Console.WriteLine("\nFollow instructions.");
System.Threading.Thread.Sleep(2000);
return;
}
total_passengers++;
Console.WriteLine("You boarded 1 Passenger." + "\nThere are " + (totalSeats - total_passengers) + " seats left.");
System.Threading.Thread.Sleep(2000);
return;
}
public void print_passengers()
{
Console.WriteLine();
foreach (var i in info_passengers)
{
Console.WriteLine(i);
}
Console.ReadKey();
}
public void calc_total_age()
{
for (int i = 0; i < total_passengers; i++)
{
totalAge += info_passengers[i].age;
}
Console.WriteLine(totalAge);
Console.ReadKey();
}
}
using System;
using System.Linq;
using System.Text;
using System.Collections.Generic;
using System.Threading.Tasks;
class Passenger{
public string name;
public int age;
public string gender;
public Passenger(string aName, int aAge, string aGender)
{
name = aName;
age = aAge;
gender = aGender;
}
public override string ToString()
{
return string.Format($"This is {name}, {gender}, {age} years old.");
}
public int GetAge()
{
return age;
}
}
you don't need to resize info_passengers array since it is enough for total passangers. When you add an extra array cell, you add a passanger to the end of arry, but you still have the empty cells in the beginnig of array with null that are causing the exception.
so remove this code
Array.Resize(ref info_passengers, info_passengers.Length + 1);
and fix this
total_passengers++;
info_passengers[ total_passengers-1] = passenger;
and don't forget to remove total_passengers++; from here
Console.WriteLine("You boarded 1 Passenger." + "\nThere are " + (totalSeats - total_passengers) + " seats left.");
and add totalAge=0 in calc_total_age
public void calc_total_age()
{
totalAge=0;
for (int i = 0; i < total_passengers; i++)
{
totalAge += info_passengers[i].age;
}
and it is not a very good idea to hide errors in your catch blok. I would make it
catch (Exception e)
{
Console.WriteLine("\n Error!!! " + e.Message);
System.Threading.Thread.Sleep(2000);
return;
}
The answer to this one is very simple!
You declare:
public Passenger[] info_passengers;
This actually creates a pointer to a Passenger array, which (like all pointers) is initially null. It does not create the actual array itself.
When your code comes to call:
Array.Resize(ref info_passengers, info_passengers.Length + 1);
the method Resize expects the array parameter to point to an array. However, info_passengers is still null. So you get the exception.
I think all you need to do is to initialise info_passengers to an new empty array, like this:
public Passenger[] info_passengers = new Passenger[]();
and then I think it'll all work.
I need to design a program that reads in an ASCII text file and creates an output file that contains each unique ASCII character and the number of times it appears in the file. Each unique character in the file must be represented by a character frequency class instance. The character frequency objects must be stored in an array list. My code is below:
using System.IO;
using System;
using System.Collections;
namespace ASCII
{
class CharacterFrequency
{
char ch;
int frequency;
public char getCharacter()
{
return ch;
}
public void setCharacter(char ch)
{
this.ch = ch;
}
public int getfrequency()
{
return frequency;
}
public void setfrequency(int frequency)
{
this.frequency = frequency;
}
static void Main()
{
string OutputFileName;
string InputFileName;
Console.WriteLine("Enter the file path");
InputFileName = Console.ReadLine();
Console.WriteLine("Enter the outputfile name");
OutputFileName = Console.ReadLine();
StreamWriter streamWriter = new StreamWriter(OutputFileName);
string data = File.ReadAllText(InputFileName);
ArrayList al = new ArrayList();
//create two for loops to traverse through the arraylist and compare
for (int i = 0; i < data.Length; i++)
{
int k = 0;
int f = 0;
for (int j = 0; j < data.Length; j++)
{
if (data[i].Equals(data[j]))
{
f++;
if (i > j) { k++; }
}
}
al.Add(data[i] + "(" + (int)data[i] + ")" + f + " ");
foreach (var item in al)
{
streamWriter.WriteLine(item);
}
}
streamWriter.Close();
}
}
}
When I run the program, the program does not stop running and the output file keeps getting larger until it eventually runs out memory and I get an error stating that. I am not seeing where the error is or why the loop won't terminate. It should just count the characters but it seems to keep looping and repeating counting the characters. Any help?
Try this approach :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace yourNamespace
{
class Char_frrequency
{
Dictionary<Char, int> countMap = new Dictionary<char, int>();
public String getStringWithUniqueCharacters(String input)
{
List<Char> uniqueList = new List<Char>();
foreach (Char x in input)
{
if (countMap.ContainsKey(x))
{
countMap[x]++;
}
else
{
countMap.Add(x, 1);
}
if (!uniqueList.Contains(x))
{
uniqueList.Add(x);
}
}
Char[] uniqueArray = uniqueList.ToArray();
return new String(uniqueArray);
}
public int getFrequency(Char x)
{
return countMap[x];
}
}
}
This might not be the ideal solution. But you can use these methods
Now if you run this it does not output each Console.WriteLine in one line, why?
I know console.writeline goes to next line when done but the problem is it jumps to next line while printing when it print the exception var it is not in the same line as the rest of the writeline
The error occurs inside the Display() function at the number 6 variable (exception) it is not in the same line as the rest of the writeline, why?
And also there are no line breaks where the error ocurs.
Ans can be any number you like.

}
Because you set exception = "\ncomplete"; at different places. The \n at the beginning is a new line character.
Remove the \n
exception = "complete";
Same problem with other texts like "\nSolution Found!".
Using string interpolation makes string formatting more readable:
Replace
Console.WriteLine("Pref:{0} Next:{1} Step:{2} Formul:{3} x:{4} Ans:{5} Status:{6}",
pref, next, stepval, formul, x, ans, exception);
by
Console.WriteLine(
$"Pref:{pref} Next:{next} Step:{stepval} Formul:{formul} x:{x} Ans:{ans} Status:{exception}");
WriteLine writes in a New Line. You should try
Console.Write()
If you want to print right after your previous print.
The value to your variable exception is the reason why the console is printing on a different basically if you put a special character \n means new line hence all the methods you are calling have this special character.
Solution remove special characters and use the Console.WriteLine or Console.Write methods
As per the code provided you have not called the method i made some changes to the code

I'm pretty new to programming and trying to get this project to return a value to main from the function, however i'm a bit sketchy on passing data and the formatting.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace most_frequent_int
{
class Program
{
static void Main(string[] args)
{
mostFreq(new int[] {1,5,2,5,24,6,5});
}
static void mostFreq(int[] number)
{
int element = 0;
int count = 0;
for (int j = 0; j < number.Length; j++)
{
int tempElement = number[j];
int tempCount = 0;
for (int p = 0; p <number.Length; p++)
{
if (number[p] == tempElement)
{
tempCount++;
}
if (tempCount > count)
element = tempElement;
{
count = tempCount;
}
}
}
Console.WriteLine("The most frequent element is: " + element + " and appears " + count + " times.");
}
}
}
I'm trying to take the value stored in count in the method and return it to main to be used again there, but i'm racking my head on how to do so.
Really sorry if this is a completely stupid question but any help is appreciated.
First change the return type of your method to what you want: (an integer)
static int mostFreq(int[] number)
{
//...
}
In your mostFreq method, use the return keyword to pass the value you need to return that way:
static int mostFreq(int[] number)
{
//...
return count;
}
Then catch the value in main and use it:
static void Main(string[] args)
{
int count = mostFreq(new int[] {1,5,2,5,24,6,5});
Console.WriteLine("Count is " + count);
}
The easiest way to communicate from a function to its caller is probably just to return the value, such as with the following example:
static int return42() {
return 42;
}
And then, in main:
int fortytwo = return42();
In other words, it entails:
ensuring the function signature returns a real type rather than void;
actually returning the desired value from the function; and
having the caller pick up the return value for later use.
Unfortunately, you have two values you wish to return. While you could return the string itself and just print it in main, it doesn't really give you the adaptability if you want to use the count and value in other ways, from other pieces of code.
That is, after all, the main reason for putting things into functions, so that common code can be called from many places.
A more adaptable way could use a number of options, such as:
using tuples, which are a class containing multiple objects;
returning an array if the variables are of the same type; or
using out parameters in the function for secondary return values.
Using that last one, for example, would entail something like (with your actual code replaced with some magic function calls for demo purposes):
static void mostFreq(int[] number, [out] int value) {
value = MagicMostCommonValueInArray();
return MagicCountOfThatValue();
}
And then, in main:
int element;
int count = mostFreq(new int[] {1,5,2,5,24,6,5}, out element);
Console.WriteLine(
"The most frequent element is: " + element +
" and appears " + count + " times.");
My advice would be to use that method rather than returning a single string.
It should be:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace most_frequent_int
{
class Program
{
static void Main(string[] args)
{
string result = mostFreq(new int[] {1,5,2,5,24,6,5});
Console.WriteLine(result);
}
static string mostFreq(int[] number)
{
int element = 0;
int count = 0;
for (int j = 0; j < number.Length; j++)
{
int tempElement = number[j];
int tempCount = 0;
for (int p = 0; p <number.Length; p++)
{
if (number[p] == tempElement)
{
tempCount++;
}
if (tempCount > count)
element = tempElement;
{
count = tempCount;
}
}
}
return "The most frequent element is: " + element + " and appears " + count + " times."
}
}
I'm having trouble with the counter variable. Every time I leave each method, count is re-initialized to 0. I haven't completed the Stay() method the Hit() method is killing. After every Hit I need to display all of the user's cards. I do not know how to do this. There has to be a more efficient way. I think all my problems arise from the problem with the Count variable.
Thanks for any help.

Look at this code
public static int Hit(int count, int playerHand, Deck d)
{
count += 1;
You are passing in a copy of count and incrementing that copy. The original value you passed in is never affected. Straightforward fixes include
Pass count by reference ref int count.
Make count a static class field rather than a local variable in Main()
A much better way would be to encapsulate your logic in a class and make count a field or property of that class, so that class methods can see and change it.
