1. Present the difference between subprogram and function,

1. Present the difference between subprogram and function, regarding the transfer of data between modules.



2. Write a program that asks the user to enter the value of Celsius degree and display the equivalent Fahrenheit degree.

Make two implementations:

2.1 Design and use a subprogram that converts the Celsius degree to Fahrenheit.

2.2 Design and use a function that converts the Celsius degree to Fahrenheit

Please transfer data between modules using arguments and parameters

The program work repetitively until the user enter space character




3. Write a program, using functions, that calculates the area and perimeter of a rectangle whose dimensions (Length and width) are provided by a user. Be sure to include in the submission;
*the problem analysis,
*design and documentation, and
*sample test data.

3.1 Provide your analysis for the following problem statement: You need to write a program that calculates the area and perimeter of a rectangle whose dimensions (Length and width) are provided by a user.

Your analysis should be clearly written and demonstrate your thought process and steps used to analyze the problem. Be sure to include what is the required output? What is the necessary input and how you will obtain the required output from the given input? Also, include your variable names and definitions. Be sure to describe any necessary formulas and sample calculations.

3.2 Provide your program design for the problem you analyzed for calculating and displaying the area and perimeter of a rectangle. Always work for modular design where possible. Be sure to use separate functions for calculating the area and perimeter of the rectangle. Other subprograms for Input and Output should be included as needed. Be sure to describe the fundamental tasks (i.e., things your program must do) needed to solve the problem so you can use a modular design. Provide pseudocode of your overall design that includes the Main module and the order of the module calls, and a Hierarchy chart for the program. Finally, display the flow charts (using Raptor, or your favorite graphics editor) for each module.

Include header and step comments in the pseudocode

3.3 Prepare at least 3 sets of input data (Test data) along with expected output for testing your program. Your test data can be presented in the form of a table as was shown in Assignment
