Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    if(num == 0){
        putchar('0');
        return; 
    }
    if(num < 0){
        putchar('-');
        putchar(' ');
        num = -num; 
    }
    char digits[10]; 
    int i=0; 
    while(num > 0){
        digits[i++] = (num % 10) + '0'; 
        num /= 10; 
    }

    for(int j=i-1; j>=0;j--){
        putchar(digits[j]);
        if(j>0){
            putchar(' ');
        }
    }
}

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