CST 180 - Function Lab 5

PART 5A:  Class Demo: Rewrite Average Speed Program
Change documentation to reference this lab activity.
Add a function to calculate the speed:

• Function Name:  mph( )
• Arguments:  Pass doubles for miles and hours
• Return Value:  The average speed (also a double)
• Prototype:  double mph(double, double);

TEST DATA SETS:
 

Miles Driven	Driving Time	MPH
282.6	4.5	62.8
1741.0	32.0
31.8	.6

Submit:

• No submission required. Used for class demonstration.

PART B:  Rewrite Lab 4 (Pay Calculation Program)

Add these functions:

• Function Name:  display( )
• Arguments:  None
• Return Value:  None
• Prototype:  void display(void);
• Action:  Display name and lab number
• Function Name:  code_not_valid( )
• Arguments:  pay code (a char)
• Return Value:  true, if bad code; false, if good code
• Prototype:  bool code_not_valid(char);
• Action:  Use do/while loop in main to enter pay code
• Test T/F value returned by function to see if another iteration is necessary
• Function Name:  get_grossPay( )
• Arguments: payRate and hoursWorked (pass by value)
• Return Value:  grossPay (assign to gPay variable in main())
• Prototype:  double get_grossPay(double, double);
• Action:  Determine gross pay amount..

 

• These are the inputs and the expected outputs.
• Your program determines Pay Rate and Pay Amount based on user inputs and internal processing.

 

Submit:

• A single turn-in document with source code and screenshot of program execution.
