Homework 5 - Multidimensional Arrays

Due: Monday, November 16, 2009 at 5:00pm

Name your solution hw5.cpp. Unlike the prior assignments, there is only one program for this assignment. Email the source file to me to submit your assignment.

This program features a simple employee paycheck calculator. Multidimensional and parallel arrays will be used to store the employee names, their pay rate and how many hours they worked each day of the week. You will have the following arrays:

An array of C-style strings to store the employee names. Each "row" is a single employee's name.
A 1D double array to store the pay rate for each employee. Each element corresponds to a single employee's pay rate.
A 2D double array to store the hours each employee worked each day of the week. Each row is 7 elements long (one element for each day of the week) and contains the hours worked by one employee.

The arrays will all be partially filled arrays for the number of "rows", but the multidimensional array will have a fixed number of "columns".

Use the following menu for the program:

  Welcome to the Employee Paycheck Calculator
  ===========================================
  1.  Add employee record(s) to the database
  2.  Print all employee records
  3.  Print the paycheck for one employee
  4.  Print paychecks for all employees

  0.  Exit
  ===========================================
  Enter selection:

Like Homework 3, your switch() statement in main() will call functions to do each task instead of doing the tasks in main(). The arrays must all be declared in main's scope and be passed to the functions. You may use a global variable or define for the maximum number of rows for the arrays. All other variables must be local to their functions.

You will have at least the following functions (you may add more functions if you want to):

add_employee - This is a void function. Its argument list will have all three arrays and a by-reference size variable. Its purpose is to APPEND employees to the arrays. It will prompt the user for how many employees they wish to add and verify that the arrays can hold that number. Do NOT overwrite size while doing this. Instead, read into a temporary integer that will be added to size to append the employees to the arrays. After reading in the number of employees, prompt the user for the employee's name and read it with getline(). Then prompt for the pay rate (dollars/hour). Then prompt for the hours worked for each day of the week.

display_employees - This is a void function. Its argument list will have all three arrays and a by-value size variable. Its purpose is to print out a record for each employee similar to the following:

Index  Name               Rate         M  Tu W  Th F  Sa Su
0      John Smith         10.50        8  8  8  8  8  0  0
1      Jane Doe           10.50        0  8  8  8  8  8  0
2      John Doe            8.90        0  8  8  8  8  8  0

print_paycheck - This is a void function. Its argument list will have all three arrays and the index number of the employee whose paycheck needs printing. Its purpose is to print a SINGLE paycheck similar to the following:
```
Employee: John Doe    Rate: 8.90   Weekly Pay:  356
```
print_all_paychecks - This is a void function. Its argument list will have all three arrays and a by-value size variable. Its purpose is to print the paychecks of ALL employess. It will loop through the arrays and call print_paycheck() for each employee in the arrays.
