Problem Statement: Calculating customer’s bill using classes
Quote
You are required to write a program for calculating the bill of a customer according to the amount spent on shopping. A customer will be an object of a class. Each object has a name, customer ID and amount spent on shopping, as its data members. You will calculate the total bill by adding tax in the spending and subtracting discount offered according to spending.
Detailed Description:
You are required to create a class named Customer.
It will have name, customer-ID and spending as its private data members.
You have to make two constructors for this class, i.e. default constructor and parameterized constructor.
Default constructor will initialize the name with “No name”, customer-id with “0” and spending with “0”;
Parameterized constructor will take three arguments i.e. name, customer-id and spending.
Create getter and setter functions for each data member of the class.
A friend function will calculate the total bill for each object of class Customer, passed to it as argument.
If total spending is less than 5000, then tax added on total spending is 5% and discount is 1%. If spending is more than 5000 and less than 10,000 then 10% tax and discount is 2% and if spending is more than 10,000 then 15% tax and 3% discount is applicable.
Remember that all this calculation will be done inside friend function.
In the main() function, create three customer type objects by using new operator. Initialize first object with default constructor, second with parameterized and take input from user for third object (use setter functions to set third object’s values taken from the user).
Calculate total bill for all three objects by passing them to friend function and then display the result of calculation as shown in example output.

This is the output
I tried to write two codes. first it was not compiling then i after compiling when i open .exe file it opens then in a blink of an eye it closes. can you please guide me?
Both are giving unknown errors
