Assignment Overview

In this practice assignment, students will learn how to identify the different parts of a program. Before writing large programs, it is important to understand how a program is organized and what each part does.

A program is not just a random collection of instructions. It usually contains a clear structure such as comments, variables, input, processing logic, output, functions, and an entry point from where execution begins.

This assignment is language-neutral. That means the focus is not on one specific programming language, but on the common parts found in most programming languages.

Learning Objectives

After completing this assignment, students will be able to:

Prerequisites

Before attempting this assignment, students should have basic knowledge of the following topics:

Assignment Instructions

Read each program carefully and identify its parts. You do not need to write actual code in a specific programming language. You only need to understand what each part of the program represents.

Program Parts Reminder

The following table reminds students about the common parts of a program.

Problem 7: Identify Parts in a Complete Program

/*
This program calculates total and average marks
of a student.
*/

CONSTANT SUBJECT_COUNT = 3

FUNCTION calculateTotal
    SET total = mathMarks + scienceMarks + englishMarks
    RETURN total
END FUNCTION

FUNCTION calculateAverage
    SET average = totalMarks / SUBJECT_COUNT
    RETURN average
END FUNCTION

ENTRY POINT
    INPUT studentName
    INPUT mathMarks
    INPUT scienceMarks
    INPUT englishMarks

    SET totalMarks = CALL calculateTotal
    SET averageMarks = CALL calculateAverage
