Vectors

[zandy]

Can somebody please help me with my vector and sorting functions. the trim and program are working but i need to output my file in "report.txt" with sorted accounts. THEN … use std::sort to sort the std::vector on balance and output to the console (std::cout) the accounts in this order to see who our largest account holders are. Any help will be highly appreciated.

For this assignment, create an account class with the following members:
class account {
private:
std::string account_code;
std::string first_name;
std::string last_name;
double balance;
public:
. . .
};
This class should have a constructor that initializes ALL members in the initialization list with data
passed in as arguments to the constructor as well as accessors for all members.
2) Write an application that populates a std::vector<account>. The application will use a std::ifstream
opened on the file, “account.dat”, which will be supplied to you. If the file cannot be opened, throw an
exception.
3) The application will then read account information from the file in the following format
account_code: 10 characters
first_name: 15 characters
last_name: 25 characters
balance: 8 digits, decimal place, 2 digits

For each set of data read, the application should use that data to construct an account object and push_back that object onto the vector. Each set of data is separated by a newline, which must be
skipped between data sets. Trim spaces from the right of the first name and last name fields upon input using the trim_right function provided.
4) Use std::sort to sort the std::vector on account number.
5) The application will then create a std::ofstream object and output the vector of accounts to a file,
"report.txt". Use any format you wish, but make sure to include all members on the output. At the
bottom of the report, include the sum of all account balances.
6) THEN … use std::sort to sort the std::vector on balance and output to the console (std::cout) the
accounts in this order to see who our largest account holders are.
