Thread: Integer to String

Hello,

I've been wrecking my brain for hours now on how to store a value stored inside an integer variable to a character string or pointer variable.

I'm using the WriteConsoleOutputCharacter function to print out some text in colour, but I'm having trouble printing out numbers. The second arg of that function requires to be a string.

For example, if I had an
int num = 5;

and I wanted
char *buffer;
or
char buffer[10];
to have the value of "5" or num, how would I go about doing that?

Currently if I try to use my integer variable for the function, I get an error: warning: passing arg 2 of 'WriteConsoleOutputCharacter' makes pointer from integer without cast.

Any ideas? Thanks for your help in advance..

_itoa() changes an int to string.
_ltoa() for longs.

Wonder if Typecasting really helps here.

like char_var=(char)int_value;

??

Your can use the sprintf function:

Code:

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

int main(int argc, char *argv[])
{
	char buf[1024];
	int i = 24;

	sprintf(buf, "The number is: %d\n", i);
	printf(buf);
	return 1;
}

Thank you very much! It seems to work..

I've looked up the function for anyone else that's interested:

Code:

#include <stdlib.h> 

char *itoa(int value, char *string, int radix);

It's said that the radix (third arg) value should be 2 - 32 though I'm not sure what value would be most appropriate for which case. If anyone knows, it would be apprciated.

Thanks again for your help!
