Pseudocode for Summing Even Numbers in a List

Objective

Design an algorithm to find the sum of all even numbers in a given list of integers.

Variables

• inputList: List of integers
• sumEven: Integer initialized to 0 to hold the sum of even numbers
• currentNumber: Integer to represent the current number being evaluated

Steps

1. Start a loop to iterate through each number in inputList.
2. For each number, check if it is even.
3. If the number is even, add it to sumEven.
4. After the loop ends, output the value of sumEven.

Pseudocode

FUNCTION SumOfEvenNumbers(inputList)
    DECLARE sumEven AS INTEGER
    SET sumEven = 0

    FOR EACH currentNumber IN inputList DO
        IF currentNumber MOD 2 = 0 THEN
            sumEven = sumEven + currentNumber
        END IF
    END FOR

    RETURN sumEven
END FUNCTION

Explanation

• Initializes sumEven to zero to start summing from zero.
• Iterates through each integer in inputList.
• Checks if the current number is even using the modulo operator.
• Adds to sumEven if the condition is met.
• Returns the final sum of even numbers after all integers are processed.

This pseudocode provides a clear and structured approach to solving the problem of summing even numbers in a list, making it easy for others to understand and implement in any programming language.
