Question

Write a program for hotel booking system using C++

Program Requirement

1. You can write any program based on the title assigned.

2. The program must fulfill ALL the requirements below. The requirements listed below are the MINIMUM requirement. Your program may extend beyond the requirements if needed.

a) Create at least one (1) base class.

b) Create at least two (2) derived classes that inherit from the base class created in 2(a).

c) Create at least one (1) object for each class and one (1) array of objects for one of the class.

d) Create at least one (1) default constructor for every classes.

f) Apply dynamic memory allocation using keyword new and delete for any object or array of objects.

g) Create at least one (1) virtual function.

h) Write sufficient comments to explain your program.

(Note : Only a reasonable level of user input checking is needed. Assume that a user will input text and numbers in good faith. He/she will not purposely enter text into a number field and will not key in non-alphanumeric characters for all text fields.)
