Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    int buffer[10];
    int i = 0;
    int soam = 0;
    if(num == 0){
        putchar('0');
        return;
    }
    if(num < 0){
        soam = 1;
        num = -num;
    }

    while(num > 0){
        int du = num % 10;
        buffer[i++] = '0' + du;
        num /= 10;
    }
    if(soam == 1)buffer[i++] = '-';

    buffer[i] = '\0';
    
    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;
}
