Homework 1 - Review cmps2010
The purpose of this homework assignment is to familiarize yourself
with C++ (Functions, Pass By Value, Pass By Reference, Pointers,
Dynamic Memory Allocation, Structures). For this homework assignment,
you will be to create a menu based program for Employee records. The
menu will prompt to either add a new employee, print one employee,
print all employees, or exit.
* 1. Add new employee *
* 2. Print one employee *
* 3. Print all employees *
* 0. Exit *
For the Employee structure definition, the employee will have
a static sized cstring for the employee's first and last name,
an integer for the employee's hours worked, and a float for the
employee's hourly payrate.
This program will use an Employee pointer to store the
array of employees, and an integer to store the current count of employees.
For option 1, each time an employee is added, you will need
to allocate a new temporary array with count + 1 employees,
copy the current array into the temporary (memberwise assignment),
deallocate the current, then set the current to point to the temporary.
You will write a function called 'allocate' to do this, description below.
For option 2, you will prompt the user for which indexed employee to
print. If the user ask for the first employee by entering 1, you will
print the contents of the employee stored in the array at index 0. You
will validate that the entered index is within range of the employee array
(1<=index<=count). If the index is out of range, prompt the user again
for a valid index.
For option 3, you will pass the employee array and the current count to a
function that will traverse the array, print the members of each object,
and calculate the $paycheck.00 (rate*hours) in monetary format.
For option 0, you will then deallocate the
employee array if necessary,
set the employee pointer to NULL, and exit the program.
- Employee* allocate(Employee* &, int&); - This function will pass
the current employee array and the current count by reference.
Allocate a new temporary array with count+1 capacity. If the current
employee array does not point to NULL, copy the current array to the
temporary array, then deallocate the current array, and return the
temporary array back to main (the function call being assinged into main's
employee pointer) ex:
emps = allocate(emps,count);
- void inputEmployee(Employee&); - This function will prompt the user
to enter values and store the inputed data into the object's members.
- void printEmployee(const Employee&); - This function will print the
members of the passed object in nice formatted output.
- void printAllEmployees(const Employee*, int); - This function will
pass the employee array and the current count of employees.
Print all the employees' members and calculate the employee's
paycheck (hours*payrate) in nice formatted output.
Once completed, you will copy your source code into your depository
