Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    char buffer[12];
    int idx = 0;
    if(num == 0){
        printf("0");
        return;
    }
    if(num < 0){
        printf("- ");
        num = -num;
    }
    while(num > 0){
        buffer[idx] = num % 10 + '0';
        idx++;
        num /= 10;
    }
    for(int i = idx - 1; i >= 0; i--){
        printf("%c", buffer[i]);
        if(i != 0){
            printf(" ");
        }
    }
}

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