REPRESENTING ALGORITHMS II - PSEUDOCODE

2. Pseudocode Conventions and Standards

Basic Pseudocode Structure

ALGORITHM_NAME

    // Header section with algorithm description

    BEGIN

        // Variable declarations (if needed)

        // Input operations

        // Processing steps

        // Output operations

    END

Common Pseudocode Keywords and Conventions

Construct	Pseudocode Keyword	Example
Algorithm Start	ALGORITHM, BEGIN	ALGORITHM CalculateAverage
Algorithm End	END	END CalculateAverage
Input	READ, INPUT, GET	READ studentName
Output	PRINT, DISPLAY, WRITE	PRINT "Hello World"
Assignment	← or =	total ← mark1 + mark2
Conditional	IF-THEN-ELSE-ENDIF	IF score >= 50 THEN
Loops	WHILE-ENDWHILE, FOR-ENDFOR	WHILE count < 10 DO
Comments	// or /* */	// This is a comment

 

Variable Declaration and Usage

• Variables are implicitly declared by their first use
• Use meaningful names (e.g., studentCount instead of sc)
• No need to specify data types in pseudocode
• Example: counter ← 0 or totalMarks ← 0
