Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    char buffer[20]; 
    int i = 0; 
    if (num == 0){
        printf("0");
    }
    if (num < 0){ 
        buffer[i] = '-';  
        printf("%c ", buffer[i]);
        num = num * (-1); 
    }

    while (num > 0) {
    buffer[i] = (num % 10) + '0';  // Convert to ASCII
    num /= 10;
    i++; 
}
    buffer[i] = '\0'; 
 
    for (int j = i - 1; j >= 0; j--){ 
        printf("%c ", buffer[j]); 
    }

}

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