Read the Announcement (http://www.daniweb.com/techtalkforums/announcement.php?f=8&announcementid=2)

No, probably it wouldn't...If you have any problem, why don't you post here?

You declared the head and tail variables inside of main function; they are not available for the f1 function.
When you declare a function, it should work like this:

int f1 (int a, int b)
{
int...

You declared the function f1 as

void f1 ();

but the definition specify that the function receive one parameter:

void f1 (int i)
{
...
}

First, when you post some code, use code tags:

2nd, why not use a newer compiler?

3rd, here is the code posted...

The rename function renames the file oldname to newname. The file formerly accessible under the name oldname is afterwards accessible as...

A month ago you posted the same question (http://www.daniweb.com/techtalkforums/thread13807-missy.html) Didn't you try to do anything in this time?

First, read this:
http://www.daniweb.com/techtalkforums/announcement.php?f=8&announcementid=2
And, 2nd, try to explain clearly what you want (honestly, I didn't undestant anything...)

char *pt;

pt = strstr (input_string, "the");
if (pt != NULL)
printf ("Found \"the\" in the string");
else
printf ("Not found \"the\" in the string");

(just an example)

char * strcasestr (const char *haystack, const char *needle)

This is like strstr, except that it ignores case in searching for the substring :lol:

char * strstr (const char *haystack, const char *needle)
It searches haystack for a substring needle rather than just a single character. It returns a pointer into the string haystack that is the...

I think the correct relations are more like
r1 = iorig + (i - iorig)sin(angle)
c1 = jorig + (j - jorig)cos(angle)
where iorig, jorig are th ecoordinates of the rotation center.
(but I'm not too...

>>does the address of the pixel vary or the value of the pixel vary.
Depends how you see this matter: let's assume the rotation center is the center of the image. So, rotating the image means the...

No, we can't...I don't think somebody will do your homework... Try to do it yourself, and, if you get into troubles, come back for help.

int x
int y
This means the compiler will process a division between 2 ints, and the result will be an int (truncated, of course).
You have to typecast those 2 operators x and y
output= ((float)...

It would be better if you would post some code...But I assume you declared the result of that 7/4 division as an int, and it should be float...

You're right, but you have to know exactly how long is the file header, how the info is stored in the file, the encoding algorithm etc...

It's not a new subject...

I assume #include <stdio.h>


int main (void)
{

int a_real,a_imaginary,j;
int b_real,b_imaginary;
int complex_number;

Thx for correction, Narue...It looks like sometimes my brain takes a break...

Just include <stdlib.h> into your .c file, then, instead "clrscr()", write "system(cls)". This is a call to a system function, that clears the screen.

"system" function is available in C, in stdlib.h. So, I guess you can use it without any restrictions.

It would be better if you will post your code...

Try use "%10.2lf" specificator format (a suggestion, you can use other values, of course :lol: ).

Try use "system(cls);" instead of "clrscr()". I assume you are using a newer compiler...

Why do you return "o" when you should return "0" (zero)?

Sure...In fact, your image (with the size 256x256 and 256 grey levels) is exactly a 2D array with the dimensions 256x256, and it has to store 256 different values, that means 1 byte => char...

According to MSDN, the Readline method returns a string, so I think you have to do the typecast - lab1 = Convert.ToInt (Console::Readline)

Take a look on this: http://www.myserverproject.net/forum/viewtopic.php?t=35. Maybe it will help you.

First, I think you should declare avgt, avgl and finalAverage as float or double. But could be useful if you specify what kind of error you get.

In fact, 1 byte = 8 bits; so a char variable can have 2^8 = 256 values; this have nothing to do with ASCII chars...

Right, I missed it. Thx, Stack...jigvesh too :D

I think you should move the printf ("\n"); outside of one of the 2 for loops:

#include<stdio.h>
#include<conio.h>
void main()
{
int a[3][4],b[3][4],c[3][4];
int i,j;
clrscr();...

I ment replace clrscr() with system ("cls") (it's equivalent, and it does another system call for you :cool: )

Hi, Riturajraina

I tried your piece of code in Dev-C++ 4.9.9.0 compiler (available for free download at www.bloodshed.net (http://www.bloodshed.net)), and it's working just fine (just delete the...

Maybe this will work:


#include <stdio.h>
#include <stdlib.h>

int add_it(int n);

int main()
