C++ Sentinel/Count Controlled Loop beginning programming

Question

Hello all this is my first post. I'm working on a homework assignment with the following parameters.

Piecework Workers are paid by the piece. Often worker who produce a greater quantity of output are paid at a higher rate.

 1 - 199 pieces completed $0.50 each 200 - 399 $0.55 each (for all pieces) 400 - 599 $0.60 each 600 or more $0.65 each 

Input: For each worker, input the name and number of pieces completed.

 Name Pieces Johnny Begood 265 Sally Great 650 Sam Klutz 177 Pete Precise 400 Fannie Fantastic 399 Morrie Mellow 200 

Output: Print an appropriate title and column headings. There should be one detail line for each worker, which shows the name, number of pieces, and the amount earned. Compute and print totals of the number of pieces and the dollar amount earned.

Processing: For each person, compute the pay earned by multiplying the number of pieces by the appropriate price. Accumulate the total number of pieces and the total dollar amount paid.

Sample Program Output:

 Piecework Weekly Report Name Pieces Pay Johnny Begood 265 145.75 Sally Great 650 422.50 Sam Klutz 177 88.5 Pete Precise 400 240.00 Fannie Fantastic 399 219.45 Morrie Mellow 200 110.00 Totals 2091 1226.20 

You are required to code, compile, link, and run a sentinel-controlled loop program that transforms the input to the output specifications as shown in the above attachment. The input items should be entered into a text file named piecework1.dat and the ouput file stored in piecework1.out . The program filename is piecework1.cpp. Copies of these three files should be e-mailed to me in their original form.

Read the name using a single variable as opposed to two different variables. To accomplish this, you must use the getline(stream, variable) function as discussed in class, except that you will replace the cin with your textfile stream variable name. Do not forget to code the compiler directive #include < string > at the top of your program to acknowledge the utilization of the string variable, name . Your nested if-else statement, accumulators, count-controlled loop, should be properly designed to process the data correctly.

The code below will run, but does not produce any output. I think it needs something around line 57 like a count control to stop the loop.

something like (and this is just an example....which is why it is not in the code.)

count = 1;
while (count <=4)

Can someone review the code and tell me what kind of count I need to introduce, and if there are any other changes that need to be made.

Thanks.

You need statements that direct output to your output file, just as the assignment said to do. The compiler can't read your mind, and it can't read your homework assignment either. It can only read your code.

You also have a problem with your input statements. The pay rates are not in the input file. All that's in the input file are the workers' names and the number of pieces they produced.
