Raising a number n to a power p is the same as multiplying n by itself p times. Write a function called power() that takes a double value for n and an int value for p, and returns the result as a double value. Use a default argument of 2 for p, so that if this argument is omitted, the number n will be squared. Write a main() function that gets values from the user to test this function.

To creat this C++ programme create a structure containing patient information like patient id, name of patient, disease description, doctor name and flag to know whether patient has an appointment (Stucture array of 5)

You have to

1. Add a new patient

2. Display patients that have appointment

3. Display all patients in the hospital of a particular doctor

4. Display all the patients that have appointment with a specific doctor

5. Display the total number of patients in the hospital

6. Book a appointment

(If we book an appointment, the total number of appointments increased by 1)

Consider the following structure used to keep record of a module: struct Module { string moduleName; string moduleCode; string lecturer; int nrStudents; } Turn the Module struct into a class. The class should have member variables for all the values in the corresponding struct. Make all the member variables private. Include public member functions for each of the following: a default constructor that sets the string member variables to blank strings, and the int member variable to 0 overloaded constructor that sets the member variables to specified values;  member functions to set each of the member variables to a value given as an argument to the function member functions to retrieve the data from each of the member variables Test the class in a program that instantiates an object of class Module. The program should then input values for the object and use the mutators to assign values to the member variables. Use the accessors to obtain the values
