Lecture 35 - Given Number Is Even or Odd

To determine whether a given number is even or odd, you can write a C++ program that takes an integer input from the user and checks its divisibility by 2. If the number is divisible by 2, it is even; otherwise, it is odd.

Here's a C++ program to check if a given number is even or odd:

cppCopy code

#include <iostream> int main() {    int number;    std::cout << "Enter a number: ";    std::cin >> number;    if (number % 2 == 0) {        std::cout << number << " is even." << std::endl;    } else {        std::cout << number << " is odd." << std::endl;    }    return 0; }

Example output:

csharpCopy code

Enter a number: 15 15 is odd.

csharpCopy code

Enter a number: 20 20 is even.

In the program, we use the modulus operator % to check the remainder when the number is divided by 2. If the remainder is 0, the number is even; otherwise, it is odd. The program then prints the appropriate message based on the result.

Feel free to run this program with different numbers to see whether they are even or odd.
