Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    char digits[5]; int i=0;
    char sign;

    if(num == 0){
        printf("0");
    }

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

    while(num > 0){
        digits[i++] = (num % 10) + '0';
        num /= 10;
    }
    if(sign == '-'){
        digits[i++] = '-';
    }

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

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