Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    if(num==0){
        putchar('0');
        return;
    }

    
    int i = 0;
    int flag = 0;

    if(num<0){
        flag = 1;
        num = -num;
    }

    char buffer[12];

    while(num){
        char value = (num%10) + '0';
        num /= 10;
        buffer[i++] = value;
    }

    if(flag){ //if negative
        buffer[i++] = '-';
    }

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

}

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