Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    char str[100];
    int i =0;
    if (num<0) {
        printf("- ");
        num = -num;}
    while(num !=0){
        str[i++] = (num % 10) + '0';
        num /=10;
    }
    if (i == 0) printf("0");
    else {
        i--;
        while (i>=0){
         printf("%c ",str[i]);
         i--;
    }
    }
}

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