Pseudo Code for Comparing Two Numbers

Purpose

The following pseudo code allows users to input two numeric values and determines which of the two is larger, then displays the result.

Pseudo Code Structure

1. Variable Declaration: Define variables to hold numeric input.
2. User Input: Prompt the user for the first and second numbers.
3. Comparison Logic: Compare the two numbers.
4. Output: Display which number is larger.

Pseudo Code

BEGIN

    // Step 1: Variable Declaration
    DECLARE NUMERIC nNum1, nNum2
    
    // Step 2: User Input
    DISPLAY "ENTER THE FIRST NUMBER : "
    INPUT nNum1
    
    DISPLAY "ENTER THE SECOND NUMBER : "
    INPUT nNum2
    
    // Step 3: Comparison Logic
    IF nNum1 > nNum2 THEN
        // Step 4: Output Result
        DISPLAY nNum1 + " is larger than " + nNum2
    ELSE
        // Step 4: Output Result
        DISPLAY nNum2 + " is larger than " + nNum1
    END IF

END

Explanation of Main Points

• Variable Declaration: Two numeric variables nNum1 and nNum2 are declared to store user inputs.
• User Input: The user is prompted to enter two numbers, captured into nNum1 and nNum2.
• Comparison Logic:
  • An IF statement checks if nNum1 is greater than nNum2.
  • If true, it outputs that nNum1 is larger.
  • If false, it outputs that nNum2 is larger.
• Output: The results are displayed directly based on the comparison.

This pseudo code provides a clear and straightforward representation of the logic needed to compare two numbers, which serves well in design and documentation phases of software development.
