The main() function takes an integer input from the user, calls a separate function to check if it’s even, and prints whether the number is even or odd.

• Defines a function isEven(int number) that takes an integer and returns true if the number is divisible by 2 (number % 2 == 0), otherwise returns false.

• In the main() function, declares an integer variable num to store user input.

• Prompts the user with "Enter an integer:" and reads the input into num.

• Calls the isEven() function with num as the argument to check if it’s even.

• If the result is true, prints "[number] is even.", otherwise prints "[number] is odd."

• Ends with return 0; to indicate successful program completion.
