Check Odd/Even Number

# Check Odd/Even Number | Basics of C++ - Software Development PDF Download

C++ is a popular programming language used for developing various types of software applications. It is a general-purpose programming language and widely used in various domains such as gaming, mobile applications, desktop applications, and more. In this article, we will explore how to check whether a given number is even or odd in C++.

## Checking Even or Odd Numbers

In C++, we can use the modulo operator (%) to check whether a given number is even or odd. The modulo operator returns the remainder of dividing two numbers. If a number is even, then its remainder when divided by 2 is 0, and if it is odd, then its remainder when divided by 2 is 1. We can leverage this property to determine whether a given number is even or odd.

Example Code:

Here is an example code snippet that demonstrates how to check whether a given number is even or odd in C++.

#include <iostream>

using namespace std;

int main() {

int num;

cout << "Enter a number: ";

cin >> num;

if (num % 2 == 0) {

cout << num << " is even" << endl;

} else {

cout << num << " is odd" << endl;

}

return 0;

}

• In the above code, we first declare an integer variable num to store the input number. We then prompt the user to enter a number using the cout and cin statements. After that, we use an if statement to check whether the given number is even or odd.
• If the remainder of the number when divided by 2 is 0, then the number is even, and we print a message indicating that the number is even. Otherwise, if the remainder is 1, then the number is odd, and we print a message indicating that the number is odd.

Example Output
Here is an example output for the above code when the input is 7.

Enter a number: 7

7 is odd

## Conclusion

In conclusion, we can use the modulo operator in C++ to check whether a given number is even or odd. This is a simple and effective way to determine the parity of a number. We hope this article has helped you understand how to check even or odd numbers in C++.
