Consider the following incomplete C++ program:
#include <iostream>
int main()
{
...
}
A) Write a statement that includes the header files fstream, string, and
iomanip in this program.
B) Write statements that declare inFile to be an ifstream variable and
outFile to be an ofstream variable.
C) The program will read data from the file inData.txt and write output
to the file outData.txt. Write statements to open both of these files,
associate inFile with inData.txt, and associate outFile with outData.txt.
D) Suppose that the file inData.txt contains the following data:
Giselle Robinson Accounting
5600 5 30
450 9
75 1.5
The first line contains a person's first name, last name, and the department
the person works in. In the second line, the first number represents the monthly
gross salary, the bonus (as a percent), and the taxes (as a percent). The third
line contains the distance traveled and the traveling time. The fourth line
contains the number of coffee cups sold and the cost of each coffee cup. Write
statements so that after the program executes, the contents of the file outData.txt
are shown as below. If necessary, declare additional variables. Your statements
should be general enough so that if the contents of the input file changes and the
program is run again (without editing and recompilin), it outputs the appropriate results.
Name : Giselle Robinson, Department : Accounting
Monthly Gross Salary: $5600.00, Monthly Bonus: 5.00%, Taxes: 30.00%
Paycheck: $4116.00
Distance Traveled: 450.00 miles, Traveling Time: 9.00 hours
Average Speed: 50.00 miles per hour
Number of Coffee Cups Sold: 75, Cost: $1.50 per cup
Sales Amount = $112.50
E) Write statements that close the input and output files.
F) Write C++ program that tests the statements in parts a through e.
