i have a problem with arrays or something missed in these text..
my program works every 500ms and i want to read first 4 double values and take average of these values and then get next 4 double values and so on... i write something about this and can you pls look on this??
if (u_dcbus_pv_act[i] > 0 && i != 0)
{
u_dcbus_pv = u_dcbus_pv_act[i];
p_dcbus_pv = p_dcbus_pv_act[i];
}
if (i >= 3)
{
for (int j = 0; j < 4; j++)
{
total_u += u_dcbus_pv;
total_p += p_dcbus_pv;
}
average_u = total_u / 4;
average_p = total_p / 4;
u_dcbus_target = average_u;
p_dcbus_pv_avg = average_p;
}
from what I understand of your description, I would do it something like this:
/* add current samples to totals */
total_u += u_dcbus_pv_act[i];
total_p += p_dcbus_pv_act[i];
/* every fourth tick, calc average and reset totals */
if (i % 4 == 0)
{
average_u = total_u / 4;
average_p = total_p / 4;
total_u = 0;
total_p = 0;
}
u_dcbus_target = average_u;
p_dcbus_pv_avg = average_p;
i++;

I want a code to generate sequence of Alphanumeric character like LLNNLLNNLL where L is the Letter and N is the number. For example if the length is 5 the sequence will be LLNNL and if the length is 6 the sequence will be LLNNLL and if 7 it would be LLNNLLN.
string alphabets = "ABCDEFGHIJKLMNPQRSTUVWX";
int length = model.VALUE_INT;
string result = "";
for (int i = 0; i < length; i++)
{
int next = _random.Next(23);
result += alphabets.ElementAt(next);
result += _randomNum.Next(1, 9);
}
This is what I have tried but condition is not fulfilling
For each position (value of i) of your output string you need to check if you need a character or an integer.
Since the pattern repeats every 4 positions, you can achieve this using the modulo operator:
for (int i = 0; i < length; i++)
{
switch (i % 4)
{
case 0:
case 1:
int next = _random.Next(23);
result += alphabets.ElementAt(next);
break;
case 2:
case 3:
result += _randomNum.Next(1, 9);
break;
}
}
Or another possibility: Add blocks of LLNN and then truncate the result to the needed length...
for (int i = 0; i <= (length/4); i++)
{
result += alphabets.ElementAt(_random.Next(23));
result += alphabets.ElementAt(_random.Next(23));
result += _randomNum.Next(1, 9);
result += _randomNum.Next(1, 9);
}
result = result.Substring(0,length);
If you want to improve these lines, you can use a StringBuilder

int arraySum (int [] a, int n)
{
int sum = 0;
n = a.size();
for (int i = 1; i < n; i++)
sum += a[i];
return sum;
}
I want to convert this code from iterative to recursive.
C# Version:
int arraySum ( int [] a, int sum = 0, int i = 0 ) /*i = 0, technically means this code is logically different from yours, however it will count every element and is just a default :)*/
{
if( i < a.Length )
return arraySum( a, sum + a[i], ++i );
return sum;
}
You need:
1- Recursive definition like: sum(n) = n + sum(n-1)
2- You need to specify where should you stop so the recursion does not last forever.
for example: if (n == 0) return 0;
based on this you can code at any language.
C++ Example:
int arraySum (int a[], int n)
{
if(n==1)
return a[n-1];
else
return a[n-1] + arraySum (a, n-1);
}

The following is the ShowTab() method, how to apply dynamic numbers and result in to the table?
using System;
const int MAX = 4;
int cage = 500/total;
int month = 1;
int adults = 1;
int babies = 0;
int total = 1;
Console.WriteLine("Month\tAdults\tBabies\tTotal");
Console.WriteLine("{0, -10}{1, -10}{2, -10}{3, -10}", month, adults, babies, total);
for(int i = 0; i < MAX; i++) {
Console.writeLine(
}
Maybe I missed something ; but if it's only about formatting somehow ; something like this should do the job :
int month = 1;
int adults = 1;
int babies = 0;
int total = 1;
Console.WriteLine ("header row"); // optional (if needed)
while (/* there is still cages to hold them */)
{
// print current state (-10 width chosen for example, negative for left align)
Console.WriteLine ($"{month, -10}{adults, -10}{babies, -10}{total, -10}");
// do the maths to update values
month = /* ... */;
adults = /* ... */;
babies = /* ... */;
total = /* ... */;
}
Here is a dummy exemple which illustrate why I choose to use width formatting specifier rather than tabulation (as hinted in one comment link).

I am trying to create an structure using abcpdf that suppose to be like this:
header
content
footer
P.S: content needs to be "front of" header and footer
In other words, I need to have my content starting from y = 0 to y = 100%; My header starting from y = 0 to y = 200; My footer starting from y = 700 to y = 100%. (Values here are just samples)
I hope I am being clear.
At the moment I have those methods:
private void CreateDocHeader(Doc theDoc, int theCount, string content)
{
theDoc.Rect.String = "0 660 600 825";
theDoc.MediaBox.String = theDoc.Rect.String;
for (int i = 1; i <= theCount; i++)
{
theDoc.PageNumber = i;
theDoc.AddImageHtml(content);
}
}
private void CreateDocFooter(Doc theDoc, int theCount, string content)
{
theDoc.Rect.String = "0 200 600 10";
theDoc.MediaBox.String = theDoc.Rect.String;
for (int i = 1; i <= theCount; i++)
{
theDoc.PageNumber = i;
theDoc.AddImageHtml(content);
}
}
private void CreateDocContent(Doc theDoc, int theID, string theContent, ref int theCount)
{
theDoc.Rect.String = "0 800 600 10";
theDoc.MediaBox.String = theDoc.Rect.String;
theID = theDoc.AddImageHtml(theContent);
while (theDoc.Chainable(theID))
{
theDoc.Page = theDoc.AddPage();
theID = theDoc.AddImageToChain(theID);
}
theCount = theDoc.PageCount;
}
Anyone?
Use Hpos and Vpos properties to do that :-
For header, do this:
theDoc.HPos = 0.5;
theDoc.VPos = 1.0;
this will keep your header in left alignment.
For footer, do this:
theDoc.HPos = 1.0;
theDoc.VPos = 0.5;
this will keep your footer in right alignment.
Hope this helps.
Addition:
For having the Z position, that is have the different tiers for the header/footer and content, use the Layer property. This property alongwith the LayerCount property, you can have the solution.
For more reference go through this documentation:-

How can I add 300 seconds to this for loop each time an iteration is made?
what I need is simple but I cant focus.
my initial seconds = 14400 and the next loop I need to add 300 seconds.. so
loop 1: seconds = 14400
loop 2: seconds = 14700
loop 3: seconds = 15000
and so on...
for (int i = 0; i < 145; i++)
{
int seconds = 14400;
TimeSpan t = TimeSpan.FromSeconds(seconds);
string time = string.Format("{0:D2}:{1:D2}:{2:D2}", t.Hours, t.Minutes, t.Seconds);
Chart1.Series["TARGET"].Points.AddXY(time, 0);
}
Put this int seconds = 14400; outside for loop. Per your post below code will add 300 seconds in each iteration.
int seconds = 14400;
for (int i = 0; i < 145; i++)
{
seconds+= 300;
}
Are you looking for TimeSpan.AddSeconds(300) ?
t.AddSeconds(300);
Here:
void example()
{
var t = TimeSpan.FromSeconds(14400);
for(int i = 0; i < 145; i++)
{
t.Add(TimeSpan.FromSeconds(300));
string time = string.Format("{0:D2}:{1:D2}:{2:D2}", t.Hours, t.Minutes, t.Seconds);
Chart1.Series["TARGET"].Points.AddXY(time, 0);
}
}
