/*3.A foodcourt provides option of prepaid vouchers. The customers can buy food from the foodcourt using those vouchers. 
The foodcourt maintains customer name, voucher id and voucher balance. Whenever a product is bought from the shops in foodcourt, 
the appropriate amount will be deducted from the voucher. Write a program in C++ to define a class FOODCOURT with data members 
voucher id and voucher balance. Create a class CUSTOMER with data member customer name. Define get member function in both classes 
to assign values to data members. Create another class VOUCHER which inherits FOODCOURT and CUSTOMER. Define a member function in 
class VOUCHER to update the voucher balance whenever a product is bought by customer. Create objects of class VOUCHER and perform the task.*/
