Convert Integer to String

Code

#include <stdio.h>

void print_integer_as_string(int num) {
    // Your logic here
    unsigned char vec[32];
    unsigned char indx;

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

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

    while(num)
    {
        vec[indx++] = ((num % 10) + '0');
        num /= 10;
    }

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

}

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