Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    if( num == 0){
        printf("0");
        return;
    }
    char buf[20];
    int i =0;
    int neg = 0;
    if(num < 0){
        neg = 1;
        num = -num;
    }
    while (num > 0){
        buf[i++] = num % 10 + '0';
      //  printf("%c ",buf[i++]);
        num = num/ 10;
    }
    if(neg){
        buf[i++] = '-';

    }
    for (int j = i - 1; j >= 0; j--){
        printf("%c ",buf[j]);
        //if(j > 0) printf(" ");
    }
    // while(i >= 0){
    //     printf("%c ",buf[i--]);
    // }
}

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