Create a factory function and constructor, Computer Engineering

Assignment Help:

1) This project will use an account class that has the members:

string account_code;

string first_name;

string last_name;

double balance;

Provide a constructor that initializes ALL members in its initialization list with data passed in as arguments to the constructor.  You will also need accessor functions to get the account code and balance and to set the balance.

In addition, include two pure virtual functions that look like the following:

virtual void monthly_update() = 0;

virtual char type() = 0;

2) Design and implement the following derived classes that will inherit from account and implement the monthly_update function in the following manner:

If the type is an 'X', skip the account record.  In other words, the account should not be processed by the rest of the program and should not appear in the result.

If the type is anything else, throw an invalid_account_type exception (that you will have to write), but DO NOT stop processing the rest of the accounts.  Instead, log the account to a file named "account.log". Trim spaces from the right of the first_name and last_name members.

4) Write a manager class that has a vector member and a main function.  In the main function, open an ifstream on the file, "account2.dat", which will be supplied to you.  If the file does not exist, throw a file_not_found exception (that you will have to write) and terminate the program after logging this to the "account.log" file.

5) For each account in the input file, invoke the factory function/class written in part

3)  Each object returned from the factory function will then be inserted into the vector.

If the account is to be ignored, or if the factory function throws an invalid_account_type exception, no account should be inserted into the vector (let alone even created).  At the end of the stream, proceed with part 6.

6) Iterate through the vector and invoke the monthly_update function for each account in the vector.

7) Using an ofstream, output each account to a new file named "update.dat" in the SAME format as "account2.dat".

8) Output the accounts in a "human readable format" to a file, "report.txt".  The output format is of your choice, but please include all the members of each account per line (including the type).

9) Write a main function that instantiates your manager class from part 4, invokes its main and takes care of any exceptions that could possibly "leak" out.
