What is a simple C program to check if a number is positive, negative, or zero?

A basic C program to check if a number is positive, negative, or zero involves taking an integer input, then using if-else conditions to determine if the number is greater than, less than, or equal to zero. The program outputs the result based on these conditions.

How do you check if a number is positive or negative in C using a ternary operator?

You can use a ternary operator to check if a number is positive or negative in C. The code ((number > 0) ? "Positive" : (number < 0) ? "Negative" : "Zero") will print whether the number is positive, negative, or zero based on the input.

Can we use a switch statement to check if a number is positive, negative, or zero?

Yes, a switch statement can be used by evaluating an expression like (number > 0) - (number < 0), which results in 1 for positive, -1 for negative, and 0 for zero. Each case in the switch then handles these values accordingly.

Why is it important to know if a number is positive, negative, or zero in programming?

Knowing if a number is positive, negative, or zero is essential for making decisions in programs, validating user inputs, controlling program logic, and performing calculations. This check is a fundamental part of conditional logic, useful in applications like finance, data processing, and gaming.

Why is zero considered neither positive nor negative?

In mathematics, zero is considered neutral as it represents the absence of quantity or direction. Thus, in programming, we typically treat zero as a special case, separate from positive or negative numbers.
