Need fixing and refining

Create a program that lets the user enroll a college student. Discounts are given for the in percentage. The user will have unpaid balance if he/she chooses to pay the partial instead of the full payment.

A. Login

Upon loading the program, the user must login to the system:

Username: regi
Password: enroll2015
If the user inputs a wrong username or password, ask the user to try again or to exit.

B. Main Menu

There are 3 choices for the main menu (type a number to choose)
1) REGISTRATION
2) PAYMENT
4) EXIT

C. REGISTRATION Function

Input Student’s Name.
There are 4 choices for the REGISTRATION menu (type a number to choose)
1) Register 5 subjects
2) Register 6 subjects
3) Register 7 subjects
4) Back to Main Menu

Display the following:

Student’s Name
Number of registered subjects
Total number of registered units (3 units per subject)
Total Tuition Fee (Php 700.00 per unit)
D. PAYMENT FUNCTION (allow only if registration is complete)

Input discount percentage.
Display the following:

Student’s Name
Number of registered subjects
Total number of registered units (3 units per subject)
Total Tuition Fee (Php 700.00 per unit)
Total discount in Peso.
Tuition Balance (tuition fee less discount)
Input Payment (payment must not be less than 30% of tuition balance)
Display unpaid balance (tuition balance less payment).

I'm done with the A and B part it works but I have a problem with my C part when I choose between the choices it doesn't work it just says "no such choice".

Why does it need fixing? Does it not work? Do you get Errors? If so, post the errors here.

And please edit your post and all of your code between code tags - http://www.cplusplus.com/articles/jEywvCM9/

Yes I get errors and I don't understand why. Please, kindly copy paste the code then you'll see the problem.
