Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    if (num < 0) {
        printf("- ");
        num = -num;
    }
    if (num == 0) {
        printf("0 ");
        return;
    }
    int digits[10]; 
    int i = 0;
    while (num > 0) {
        digits[i++] = num % 10;
        num /= 10;
    }

    // Print digits in correct order
    for (int j = i - 1; j >= 0; j--) {
        printf("%d ", digits[j]);
    }
}

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