Convert Integer to String

Code

#include <stdio.h>
void print_integer_as_string(int num) {
    if(num ==0)
    {
        printf("0");
        return;
    }
    if(num<0)
    {
        printf("- ");
        num*= -1;
    }
    int i=0;
    char buf[32];
    while(num>0)
    {
        int digit = num %10; 
        buf[i] = digit + '0';
        num /= 10;
        i++;
    }
    for(int j = i-1;j>=0;j--)
    printf("%c ",buf[j]);
}
int main() {
    int num;
    scanf("%d", &num);
    print_integer_as_string(num);
    return 0;
}
