Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    if(num == 0) {printf("0"); return;}
    int i = 0, is_neg = 0;
    char str[10];

    if(num < 0){
        is_neg = 1;
        num*=-1;
    }

    while(num>0){
        str[i] = (num%10)+'0';
        i++;
        num/=10;
    }
    if(is_neg) {str[i] = '-'; i++;}
    str[i] = '\0';
    i--;
    while(i!=-1){
        printf("%c", str[i]);
        i--;
        if(i!=-1) printf(" ");
    }
}

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