Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    char buffer[32];
    int i = 0;
    int is_negative = 0;

    if (num == 0) {
        printf("0 ");
        return;
    }

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

    
    while (num > 0) {
        int mod = num % 10;
        num /= 10;
        buffer[i++] = mod + '0'; 
    }

    
    if (is_negative) {
        printf("- ");
    }

  
    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;
}
