1. (you implemented this in the previous program) the default

constructor to initialize the state of your class. The default constructor

will read the data from the file callstats_data.txt into the dynamic array

call_DB. If call_DB becomes full, the function should call the function

double_size to double the size (capacity) of call_DB. Remember, count

and call_DB are private members of your class and do not need to be

passed to an member function of your class.

2. (you implemented this in the previous program) is_empty is a Boolean

public member function of the class. It has no formal parameter because

count is a member of the state of the class (private member) and does not

need to be passed to it because the state of the class if known to all

member functions of the class. If count == 0 then true is returned;

otherwise false is returned.

3. (you implemented this in the previous program) is_full is a Boolean

public member function of the class. It has no formal parameters because

count and size are members of the state of the class (private members)

and do not need to be passed to it because the state of the class if known

to all member functions of the class. If count == size then true is return;

otherwise false. The size is the capacity which is the total number of cells

allocated to call_DB.

4. (you implemented this in the previous program) search is an integer

public member function that has only one formal parameter, the key. key

is the cell phone number for the record you are search for. The array of

records, call_DB and count are members of the state of the class and do

not need to be passed to a member function of the class; The function will

return the location of key in call_DB if it is there; otherwise -1 is

returned.

5. (you implemented this in the previous program) add is a void public

member function that inserts the information for a call record into

call_DB. Duplicates cell numbers are ok; add will prompt the user for the

firstname, lastname, cell number, relays and call length. You may call

process record to re-process when you add a new record. add has no

formal parameters.

6. overload operator - as a member function of call_class with

chaining. This function will have the same functionality as the

remove function. Recall the following about the function remove:

remove is a void public member function thaqt deletes all records with

the cell number stored in key. If duplicate records exist with the same cell

number they must all be deleted. remove has only one formal

parameter, the key. Note, because we are overloading with chaining

we must return the current object *this.

7. (you implemented this in the previous program) double_size is a void

public member function that doubles the capacity of call_DB.

double_size has no formal parameters because size, count and call_DB

are all members of the state of the class, call_class. First, size is multipled

by two; second, memory is allocated using call_record *temp=new

call_record[size]; third the records in call_DB are copied into temp with

the statement temp[i]=call_DB[i] using a for loop. Forth, the old

memory for call_DB is de-allocated using delete [ ] call_DB; Finally,

call_DB is set to point to the new memory pointed to by temp using

call_DB = temp.

8. (you implemented this in the previous program) process

is a void public member function the has no formal parameter because

call_DB and count are members of the state of the class.. The function

process will calculate the net cost of a call (net_cost), the tax on a call (call_tax) and the total cost of the call (total_cost) using the number of relay stations (relays) and the length in minutes of the call (call_length) for all call records stored in call_DB. Please consider the following:

The tax rate on a call (call_tax) is simply based on the number of relay stations (relays) used to make the call (0<= relays <=5 then call_tax = 1%; 6<= relays <=11 then call_tax = 3%; 12<= relays<=20 then call_tax = 5%; 21<= relays <=50 then call_tax = 8%; relays >50 then call_tax =12%) .

The net cost of a call is calculated by the following

formula: net_cost = ( relays / 50 x 0.40 x call_length).

The tax on a call is equal to net_cost x call_tax / 100.

The total cost of a call (rounded to the nearest hundredth) is

calculated by the following formula: total_cost = net_cost + call_tax . All tax and cost calculations should be rounded to the nearest hundredths.

9.

10.the destructor to de-allocate all memory allocated to call_DB. This function has no formal parameters because call_DB is a member of the state of the class. It will be called automatically by the compiler.

Use the driver call_stats7.cpp to help you implement this program. Output Format for the overload operator<<:

Consider the following sample output table when designing and implementing "operator<<". See section Format of Output below.

(The output is in the following order: firstname, lastname, cell phone number, relays, minutes, net cost, tax rate, call tax, total call cost)

overload operator << as a friend function of call_class with

chaining. This function will have the same functionality as the

print function ( it will print call_DB to the screen). Recall the

following about the function print: print is a void public member

function that has no formal parameters because count and call_DB are

members of the state of the class. The function will print every field of

every call_record in call_DB to the screen.

Input Stream:

In the assignment you will declare one ifstream to bind your input to the file "callstats_data.txt" Whenever a program performs file i/o you must include the "fstream" library.

Format of the input data file(input filename is "callstats_data.txt"): Do not include column titles

(The order of the columns are as follows: firstname, lastname, cell phone number, relays, minutes)
