Convert Integer to String

Code

#include <stdio.h>
#include<stdlib.h>
void print_integer_as_string(int num) {
    // Your logic here
    int arr[100],i=0;
    if(num==0)  {printf("0");   return;}
    if(num < 0) {
        printf("- ");
        num = abs(num);
    }

    while(num){
        arr[i] = num %10;
        i++;
        num = num/10;
    }

    for(int j =i-1;j>=0;j--){
    printf("%d ",arr[j]);
    }
}

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