Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    char result[20];
    int val = num < 0 ? 0 - num : num; 
    int i = 0; 
    while (val > 0)
    {
        int index_s =  (val % 10);
        result[i++] = index_s + '0';
        val = val /10;

    }
    if ( num < 0)
    {
        printf("- ");
    }
    if (num == 0)
    {
        printf("%d",num);
    }
    for (int c = i - 1 ; c >= 0   ; c-- )
    {
        printf("%c ",result[c]);
    }
}

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