Uncovering the Secrets of Even and Odd Numbers in C++

When it comes to programming in C++, understanding the basics of even and odd numbers is crucial. But how do you determine whether a number is even or odd? The answer lies in the modulus operator (%).

The Magic of Modulus

The modulus operator (%) returns the remainder of a division operation. When you divide an integer by 2, if the remainder is zero, the number is even. Otherwise, it’s odd. This simple yet powerful concept is the foundation of checking whether a number is even or odd.

Putting it into Practice

Let’s take a look at an example program that uses an if…else statement to check whether a number is even or odd. In this program, we use the expression n % 2 == 0 to determine whether the number is even or odd.


if (n % 2 == 0)
cout << "The number is even.";
else
cout << "The number is odd.";

Simplifying with Ternary Operators

But what if we want to simplify our code? That’s where ternary operators come in. A ternary operator is a shorthand notation of an if…else statement. It allows us to write concise and efficient code.


cout << (n % 2 == 0)? "The number is even." : "The number is odd.";
