Convert integer into an array

Question

I am working on a C program, and I am coming across a small problem. I don't know how to convert an integer (say 2007) into a char array. Is there a function in the C libraries to do that for me?

To clarify, I'd like to take 2007 and store it in some char array[4] ={ '2', '0', '0', '7', '\0' };

I was thinking something like sprintf, but I'm not sure. Anyways, any help/hints would be appreciated.

Thanks, Michael

Answer 1

You can do that with sprintf, or more safely snprintf.

Here's a contrived example:

#include <stdio.h>
#define MAX_LEN 5

char str[MAX_LEN];
snprintf(str, MAX_LEN, "%d", 2007);
