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 buffer[100];
    int i=0;
    while(num>0){
        int last_digit = num%10;
        buffer[i]=last_digit+'0';
        i++;
        num/=10;
    }
    for(int j=i-1;j>=0;j--){
        putchar(buffer[j]);
        putchar(' ');
    }
}

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