C program to find the negative or positive number using bitwise operators and ternary operators

#include <stdio.h>
// Total bits required to represent integer
#define BITS sizeof(int) * 8
//Logic to check whether a number is positive
int isPositive(int n)
{
    return (!( n & (1 << (BITS -1 )) | (!n)));
}
int main()
{
    int num;
    printf("Enter any number: ");
    scanf("%d", &num);
    isPositive(num)? printf("Positive number\n"):(num)? printf("Negative number\n"): printf("Zero\n");
    return 0;
}

Output:

Enter any number: -10
Negative number

Enter any number: 10
Positive number

Enter any number: 0
Zero
