You will implement a program called "call_stats4.cpp" to process customer call records. You will read the records in a datafile into an array of call records, then process each call record in the array, and finally print the array of call records to a datafile. Remember, each customer call record contains seven fields, which are as follows: 1) a ten digit cell phone number (string, no dashes), 2) the number of relay stations used in making the call (integer), 3) the length of the call in minutes (integer), 4) the net cost of the call (double), 5) the tax rate (double), 6) the call tax (double) and 7) the total cost of the call (double). Your program will have 3 functions: Input, Process, and Output. Your main program will call each function once. Following are the descriptions of the functionality of each function

1. The void function Input will have two parameters: the call record array called

call_DB, and the count. call_DB, and count should be initialized in your main

program. The global integer constant SIZE should be set to 200. count should be

initialized to 0. The function will read the cell_number, relays, and call_length (in

minutes) into the a call record in call_DB (call_DB[i] is an individual call record)

from the input data file. Remember, count should be passed by reference.

2. The function Process will have two parameters: call_DB and count. 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 a call record. Please consider

the following:

a. 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 tax_rate = 1%;

6<= relays <=11 then tax_rate = 3%; 12<= relays<=20 then tax_rate = 5%;

21<= relays <=50 then tax_rate = 8%; relays >50 then tax_rate =12%) .

b. The net cost of a call is calculated by the following formula: net_cost = (

relays / 50 x 0.40 x call_length).

c. The tax on a call is equal to net_cost x tax_rate (divide by 100 if tax rate

was not converted into a decimal earlier).

d. 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.

hint: call_DB[i].net_cost = (call_DB[i].relays/50.0)*0.40* (call_DB[i].call_length);

3. The function Output will have two parameters: call_DB and count. Note that

call_DB and count will not change inside this function. Output will print every field

of every call record stored in call_DB to the file weekly6_call_info.txt. The fields

should be printed in the following order: 1) cell phone number, 2) number of relay

stations, 3) length of the call in minutes, 4) net cost, 5) tax rate, 6) call tax, 7) total

cost of call. See the sections below called "Input Stream" and "Format of Output"

for more information. See the section Format of the input data file(input

filename is "call_data.txt").

hint: cout<

You may implement more functions if you find it necessary. Please start the assignment

ASAP and ask questions to make sure you understand what you must do. Remember to

follow all style rules and to include all necessary documentation (consistent, indentation,

proper variable names, pre/post condition, program header, function headers, and so

forth.)

Finally, your input data file (call_data.txt) should be in the same directory as your

program source file (call_stats4.cpp).

Input Stream:

In the assignment you will declare one ifstream to bind your input to the file

"call_data.txt" and one ofstream to bind your output to the file weekly6_call_info.txt .

Whenever a program performs file i/o you must include the "fstream" library. Add the

following statements to your program:

For source file, "call_stats4.cpp":

Add "#include " to your # include statements in your source file.

Add "include to your # include statements in your source file.

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

column titles
