There's a nonstandard function:
char *string = itoa(numberToConvert, 10); // assuming you want a base-10 representation
Edit: it seems you want some algorithm to do this. Here's how in base-10:
#include <stdio.h>
#define STRINGIFY(x) #x
#define INTMIN_STR STRINGIFY(INT_MIN)
int main() {
int anInteger = -13765; // or whatever
if (anInteger == INT_MIN) { // handle corner case
puts(INTMIN_STR);
return 0;
}
int flag = 0;
char str[128] = { 0 }; // large enough for an int even on 64-bit
int i = 126;
if (anInteger < 0) {
flag = 1;
anInteger = -anInteger;
}
while (anInteger != 0) {?
str[i--] = (anInteger %?10) + '0';
anInteger /= 10;
}
if (flag) str[i--] = '-';
printf("The number was: %s
", str + i + 1);
return 0;
}
