Check Whether Number is Positive or Negative or Zero: C Program

#include < stdio.h >

int main()
{
    int a;

    printf("Enter an integer number\n");
    scanf("%d", &a);

    (a > 0) ?
    (printf("%d is positive\n", a)) :
    ( (a < 0) ?
      (printf("%d is Negative\n", a)) :
      (printf("%d is Zero\n", a))  
    );

    return 0;
}

Output 1:
Enter an integer number
15
15 is positive

Output 2:
Enter an integer number
-2
-2 is negative

Output 3:
Enter an integer number
0
0 is zero

In above C source code, we are using nested ternary / conditional operator. First we check if a is greater than 0, if its true then the user entered number is positive. If its false, then we check if a is less than 0 using nested ternary / conditional operator. If that is true, then a is negative, else the user entered number is 0.
