Question

I need to get this two last parts of my project done by tonight. If you see something wrong with the current code feel free to fix it. Thank you!

Project 3 Description

In this project, use project 1 and 2 as a starting point and complete the following tasks.

Create a C++ project for a daycare. In this project, create a class called child which is defined as follows:

private members:

• string First name
• string Last name
• integer Child id number
• integer Number of weeks attended
• string Teacher first name
• string Teacher last name
• integer Classroom number
• double Balance (amount due)
• static constant double rate and set the rate to 200.75

public members:

• argument constructor to assign values to data members of objects.
• default constructor to assign default values to data members of objects.
• a void method to calculate the balance
• a void method to print data of a child object
• set methods for all the data members (except the rate data member)
• get methods for all the data members.
• create a static method called filePrint to save the data of an object to a text file. make sure to pass the object as an argument.  

in the main function:

create multiple objects (at least 3) and test the methods.

---------------------

Project 4 Description

In this project, use project 3 as a starting point and complete the following tasks.

update project 3 to include exception handling.

when the user is asked to enter the payment inside the balance method, if the user entered a negative value or a value that is grater than the current balance, you should throw an exception using the payment variable. when the exception is catches, print the amount of unaccepted payment with a message of nonacceptance.
