Summary
Programming involves designing a program to calculate the area and perimeter of a rectangle. Students learn how to structure a program and use modules to perform specific tasks.
Program Design Strategy
The program starts with a main module. It declares variables, gets user input for the rectangle's dimensions, and calls other modules to calculate and display the area and perimeter.
Pseudocode for Modules
The pseudocode shows how to write the main module and three other modules. These modules handle input, calculations, and output. Each module has a clear purpose.
Test Data and Results
Test data is provided to check if the program works correctly. The table shows input values, expected outputs, and actual outputs for several test cases.
Key terms
- Module
- A separate part of a program that performs a specific task.
- Pseudocode
- A way to write out the steps in a program without using a specific programming language.
- Variables
- Containers for storing data values that can be used and manipulated within a program.
- Test Data
- Input values used to check if a program produces the correct output.
- Flow Charts
- A diagram that represents a workflow or process.
- Hierarchy Chart
- A diagram that shows the structure of a program and how its parts relate to each other.
Questions this document helps with
