Any number that can be perfectly divisible by 2 is known as an even number. While the one which does not divides by 2 perfectly is known as an odd number.

Perfectly divisible means, that the number on division produces 0 as remainder.

Algorithm:

Prompt the user to input a number.
Use the modulo operator (%) to check if the remainder of the number divided by 2 is 0.
Use an if statement to determine if the number is even or odd. If the remainder is 0, the number is even. Otherwise, it is odd.
Print a message indicating whether the number is even or odd.
Exit the program.

The below code checks if the integer entered by the user is even or odd:

#include <iostream>\nusing namespace std;\nint main()\n{\n    int num;\n    //Input the number\n    cout<<\"Enter an integer: \";\n    cin>>num;\n    if (num % 2 == 0)//check its divisibility with 2\n         cout<< num << \" is even.\";\n    else\n        cout<< num <<\" is odd.\";\n    return 0;\n}\n

Output:

Enter an Integer:234\n\n234 is even.\n
