Lab Assignment #1

Lab Assignment #2

Due Tuesday, July 15 at the beginning of class

The assignment is problem #13 on page 131 (The Maripot Carpet Store) of the Lambert, Nance, and Naps book. This assignment focuses on implementing functions using value parameters and reference parameters. It also provides an opportunity to practice with formatting output. I have added some additional requirements and restrictions:

You must use the program template on the back of this handout. There are 4 required functions that you have to implement. Partial declarations are given for each so you have a starting place. You may implement additional ones if you like, but these 4 must be defined.
Detailed comments need to be added to each of the four functions, just above their definitions, as well as comments within the body of each function.
All four customers need to be calculated and a grand total for all of them will be displayed at the end of the program.
Before you begin to implement the code, you should fill in the missing parameter information for all of the functions. This may be the most difficult part for some. DO IT EARLY and submit it to me, either via email or on paper Thursday.
In addition to the C++ code you will hand in, also hand in a structure chart that represents your program. This doesn't have to be drawn with a computer; hand drawn will be fine, but make sure its legible.

This is the template you must use:


#include <iostream.h>
#include <iomanip.h>

// function declarations
float doCustomer(int customer);
void getData(int customer /* more here */ );
void calculateCosts( /* parameters go here */ );
void printResults(int customer /* more here */ );

void main(void)
{
	float charge1  /* more here */;
	float grandTotal;
	charge1 = doCustomer(1);

	// do other 3 customers here
	// calculate grand total

	cout << "Total for all customers: " << grandTotal << endl;

}

float doCustomer(int customer)
{
	float charge;
	// more data declarations, you'll need at least 9 more

	getData(customer /* more here */ );
	calculateCosts(/* more here */);
	printResults(customer /* more here */);

	return charge;
}

void getData(int customer /* more parameters here */)
{
	cout << "Accepting data for customer " << customer << endl;
	// get input here
}

void calculateCosts(/* more parameters here */)
{  
	// calculate costs here
}

void printResults(int customer /* more paramters here */)
{
	cout << "Data for customer " << customer << endl;
	// print results here
}
