Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    if (num < 0){
        printf("- ");
        num = -num;
    }
    else if (num == 0){
        printf("0");
        return;
    }

    if ( num >= 10){
        print_integer_as_string(num / 10);
    }
    putchar('0' + (num % 10));
    printf(" ");

    // Your logic here
}

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