i need help with this program in c++

the skeleton of the program is below:

1. Read the contents ef a datafilel one record at a time; 2. Process the data that was read frem the datafile one record at a time: 3. Be able to use the fstream library 4. Be able to use records (class with only data); S. Be able to use an ifstream ebject This assignment is an extension of Assignment#1 . You will implement a program 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 (doubleL 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 until the end of the datafile has been read. Following are the descriptions of the functionality of each function: to process customer call records. Each customer 1The void function "h purr, will have two parameters: an input file stream called in", and a customer call record called "call records" The functiorn will read the cell number, relays, and call length, in minutes, into the a call record from the data file. 2. The function "Precess" will calculate the net cost of a call (net cost), the tax on a call (call sax) 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 recoed Please consider the following: The ter rate on a call (call-tox) s simply based on the number of relay stations (relays) used to make the call (-relays50 then call tax-12%) The met cost ef a call is calculated by the following fomula: met cst-rels/50 x 0.40 x call length) b. c. The ax on a call is equal to net cost x call ax/100 d. The total cost of a call (rounded to the nearest hundredth) is calculated by the follow ing formala total cost met cost+ call x. All tax and cost calculations should be rounded to the nearest hundredths 3. The function "Outur" will print every field of a call record. 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 filelinput filename is call data.xr You may implement assignment ASAP and ask questions to make sure you understand what you must do. Remember to follow all style nules and to include all necessary documentation (oonsistent, indentation, proper variable names, pre post condition, program header, function headers, and so forth.) more functions if you find it necessary. Please start the Finally, your input data file (call data txt) should be in the same directory as your program source file (call Satscpph c. The tax on call is equal to net cost xcall tax / 10 d. The total cost of a call (rownded to the nearest hundredth) is calculated by the following formula: sotal cos-net cst+ call fax. All tax and cost calculations should be rounded to the nearest hundredths 3. The function "Output" will print every field of a call record. The fields should be printed in the following order: 1) cell phone number, 2) mumber of relay stations, 3) length of the call in minutes, 4) net cost, 5) tax rate, 6) call tax, 7) total cost of call.
