The old Morgage Calculator problems sequential file wont read in

[hollywoood69]

I am having a problem writing from a outside file. here is the assignment.

Write the program as an object-oriented C++ program that allows the user to select which way they want to calculate a mortgage: by input of the amount of the mortgage, the term of the mortgage, and the interest rate of the mortgage payment or by input of the amount of a mortgage and then select from a menu of mortgage loans: 7 year at 5.35%, 15 year at 5.5%, and 30 year at 5.75% (use an array for the mortgage information and read the interest rates to fill the array from a sequential file). In either case, display the mortgage payment amount. Then, list the loan balance and interest paid for each payment over the term of the loan. On longer term loans, the
list will scroll off the screen. Do not allow the list to scroll off the screen, but rather display a partial list and then allow the user to continue the list. Allow the user to loop back and enter a new amount and make a new selection, or quit. Insert comments in the program to document the program.

I am not sure if i am doing it right, of if i am just way off. Can someone help me?

Here is my main file:

Here is my other file that is part of the assignment:

void MortgagePayment::enterPrincipal() //This is the function for the user input of loan amount  
{
	cout << "\t\tEnter the total amount of the loan:$ "; //User input
	cin >> this->principal;
}

And here is the header file:

//Jeremy Johnson
//PRG 411
//Instructor: Charles Ford


class MortgagePayment { 
public: 
	void openingHead(); //Introduction to the program
	void enterPrincipal(); //This is where the principle is entered
	double principal; //principle
	double interest; //Interest
	int term; //Term
};

Here is the cr15.txt

7 5.35
15 5.5
30 5.75

Thank you everyone!! Any help from your guys would be great.
