Function that accepts one input parameter

Assignment Help Basic Computer Science
Reference no: EM13850119

The Assignment:

Using Pseudocode, create your own function that accepts one input parameter and returns a float number. You decide the theme.

You should provide the pseudocode and an example call. Be sure to provide an overview of what your function is doing.

LAB

Overview:

This hands-on lab allows you to follow and experiment with the critical steps of developing a program including the program description, analysis, test plan, design (using pseudocode visualization), and implementation with C code. The example provided uses sequential, repetition, selection statements and two user-defined function.

Program Description:

This program will provide options for a user to calculate the square or cube of a positive Integer input by a user. The program will prompt theuser to enter an Integer and then prompt the user if they want to calculate the square of the cube of the number. Based on the inputs of the user, the program will output the square of the cube of the positive integer. The program will then print the Integer and square or cube of the integer based on the user's original choice. The program will continue to prompt the user for Integers and their calculation choice until the user enters a negative integer. The square and cube calculations should be calculated using a function.

Analysis:

I will use sequential, selection, and repetition programming statements and functions for the cube and square calculations. 
I will define three Integer numbers: IntValue, MenuSelect, Results to store the Integer value input by the user, the Menu selection (1 for Square, 2 for Cube) of the user, and the results of the Square or Cube functions. 
The Square function will take one Integer as input and return one Integer as the output. The calculation within the Square function is: Results =IntValue * IntValue
For example, if 10 was entered as the IntValue. Results = 10*10 = 100 
The Cube function will take one Integer as input and return one Integer as the output. The calculation within the Cube function is: Results =IntValue * IntValue*IntValue
For example, if 10 was entered as the IntValue. Results = 10*10*10 = 1000 

A repetition loop can be used to loop through iterations until a negative is entered:
while(intValue > 0) (
...
End For

Test Plan:

To verify this program is working properly the input values could be used for testing:

Test Case

Input

Expected Output

1

IntValue=10
MenuSelect=1

Square of 10 is 100

2

IntValue=10
MenuSelect=2

Cube of 10 is 1000

3

intValue=-1
MenuSelect=N/A

Program exits

Pseudocode:

// This program will provide options for a user to calculate the square

// or cube of a positive Integer input by a user.
// Start Main program
Main

// Declare variables
Declare intValue, menuSelect,Results as Integer

// Set intValue to positive value to start loop
Set intVal = 1;

// Loop While input is a positive number

While intValue > 0

Print "Enter a positive Integer to calculate the square or cube; OR a negative Integer to exit the program. "
Input intValue

// Only perform menu and function calls is integer is positive 
If intValue > 0 Then
Print "Enter 1 to calculate Square, 2 to Calculate Cube "
Input menuSelect

If menuSelect == 1 Then
// Call the Square Function
Set Results = Square(intValue)
Print intValue,Results
Else If menuSelect == 2 Then
// Call the Cube function
set Results = Cube(intValue)
Print intValue,Results 
Else
Print "Invalid menu item, only 1 or 2 is accepted"
End If
End If

END While

// End of Main program
End Program

// Square Function
Function Square(value) as Integer
Set Square = value*value
End Function

// Cube Function
Function Cube(value) as Integer
Set Cube = value*value*value
End Function

The following is the C Code that will compile in execute in the online compilers.

Setting up the code and the input parameters in ideone.com:

Note the Input values for this run were:
10 
1
10
2
-99
You can change these values to any valid integer values to match your test cases.

Learning Exercises for you to try:

Using the Square and Cube functions are models, how would create a function name Shrink that would take an Integer and return the Integer divided by 2?

What would happen if we removed the following code from our design?

If intValue > 0

(Hint: You can try in the C code, or walk through it in the Pseudocode to see what happens.)

What happens if you entered a 4 for the menuSelect variable?

Try to modify the design and add and use an additional function. Describe your approach. What issues did you face?
