Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    char digits[10] = {0};
    int index = 0;

    if (num < 0) {
        printf("- ");
        num = -1*num;
    } else if (num == 0) {
        printf("0");
        return;
    }

    while (num) {
        digits[index++] = (num % 10) + 48;
        num = num / 10;
    }

    for (int i = index-1; i >= 0; i--) {
        printf("%c ", digits[i]);
    }
}

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