A: Create a new file for Payroll Information
B: Enter Payroll Information
C: List Payroll Information
X: Exit the Payroll Information Module
How to Begin Project:
1. Create project P08
2. Add text file output.txt
3. Add text file P08.txt
4. Add C++ source file P08.cpp
5. Copy-and-paste the source code below, and implement options A through C.
6. If the project is built and executed at this point, there will be several
warning generated by the compiler, but the program should compile as-is.
7. See the textbook for similar examples.
Test Data:
Enter the data listed below using option B.
Your program will be saving the records in P08.txt as it is entered.
1018 9.50 50 10 25 30
1005 5.00 30 35 40 50
1002 8.00 50 50 10 40
General Processing:
See the comments included with the source code provided for hints on what
needs to be coded for each function. See the textbook for similar examples.
Requirements:
Code the createNewFile, enterInfo, and listInfo functions.
Turn in:
P08.cpp, p08.txt, and
sample output (output.txt) from the three options (A, B, and C)
