Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    char arr[100];
    int index = 0;

    if(num < 0){
        arr[index++]='-';
        num = -1*num;}
        else if(num == 0){
               arr[index++] = '0';
        }
    
    while(num){
        arr[index] = (num%10) + '0';
        index++;
        num = num/10;
    }
    int start = index-1;
    int end = 0;
    if(arr[0] == '-')
       {
        printf("%c ",arr[0]);
        end = 1;
       }
    for(int i=start;i>=end;i--){
        printf("%c ",arr[i]);
    }
}

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