LAB 3.5 Reading and Writing to a File

Bring in billfile.cpp from the Lab 5 folder. The code is as follows:

// This program will read in the quantity of a particular item and its price.

// It will then print out the total price.

// The input will come from a data file and the output will go to

// an output file.

// PLACE YOUR NAME HERE

#include #include usingnamespacestd;

int main()

{
ifstream dataIn;	//	defines an input stream for a data file
ofstream dataOut;	//	defines an output stream for an output file
int quantity;	//	contains the amount of items purchased
float itemPrice;	//	contains the price of each item
float totalBill;	//	contains the total bill, i.e. the price of all	items

dataIn.open("transaction.dat"); // Thisopens the file. dataOut.open("bill.out");

// Fill in the appropriate code in the blank below

<< setprecision(2) << fixed << showpoint; // formatted output

// Fill in the input statement that brings in the

// quantity and price of the item

// Fill in the assignment statement that determines the total bill.

// Fill in the output statement that prints the total bill, with a label,

// to an output file

return 0;

}

Exercise 1: Notice that this is an altered version of Lab 3.1. This program gets the information from a fileand places the output to a file. You must

create the data file. Your instructor will tell you how to create the data file and where to put it. Create a data file called transaction.dat that has the following information:

22

10.98

Exercise 2: Fill in the blank and the statements that will read the data from the file and print thefollowing to bill.out:

The total bill is $241.56
