write a pseudocode to check if a number is even or odd

Answer 1

Sure! Here’s a simple pseudocode to check if a number is even or odd:

BEGIN

    FUNCTION IsEvenOrOdd(number)
    
        IF number MOD 2 = 0 THEN
            PRINT "The number is even."
        ELSE
            PRINT "The number is odd."
        ENDIF

    END FUNCTION

    // Main program
    DECLARE number AS INTEGER
    PRINT "Enter a number: "
    INPUT number

    CALL IsEvenOrOdd(number)

END

Explanation:

1. The function IsEvenOrOdd takes an integer input called number.
2. It checks if number modulo 2 equals 0. If true, the number is even; otherwise, it is odd.
3. The main program declares a variable to hold the number, prompts the user for input, and then calls the function to determine if the number is even or odd.
