Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    char buf[6]; 
    char *out = buf;
    int count =0;
    int minus = 0;
    if (num < 0) {
        minus = 1;
        num *= -1;
    }
    if (num==0) {
        *(out++) = '0';
        count++;
        }
    else {
        while (num) {
            *(out++) = (num % 10) + '0';
            num /= 10;
            count++;
        }
    } 
    if (minus) {
        *(out++) = '-';
        count++;
    }
    *out = '\0';
    for (int i = count-1;i>=0;i--){
         printf("%c", buf[i]);
         if (i>0) printf(" ");
    }
}

int main() {
    int num;
    scanf("%d", &num);
    print_integer_as_string(num);
    return 0;
}
