Raising a number n to a power p is the same as multiplying

Question

Program :-1

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 double value. Use a default argument of 2for p, so that if this argument is omitted the number will be squared. Write a main () function That gets values from the user to test this function.

A point on the two dimensional plane can be represented by two numbers: an X coordinate and a Y coordinate. Foe example (4,5) represents a point to the right of the origin along with the X axis and 5 units up the Y-axis. The sum of two points can be defined as a new point whose X coordinate is the sum of the X coordinates of the points and whose Y coordinate is the sum of their Y coordinates.

Write a program that uses a structure called point to model a point. Define three points and have the user input values to two of them. Than set the third point equal to the sum of the other two and display the value of the new point. Interaction with the program might look like this:

Enter coordinates for p1: 3  4
Enter coordinates for p2: 5  7
Coordinates of p1+p2 are:8,11

Program :- 3

Create the equivalent of a four function calculator. The program should request the user to enter a number an operator and another number. It should then carry out the specified arithmetical operation: adding, subtracting, multiplying or dividing the two numbers (it should use a switch statement to select the operation). Finally it should display the result.

When it finishes the calculation, the program should ask if the user wants to do another calculation. The response can be 'Y' or 'N'. some sample interaction with the program might look like this.

Enter first number, operator, and second number.10/3
Answer=3.333333
Do another (Y/N)? Y

Enter first number, operator, and second number 12+100
Answer=112
Do another (Y/N)? N

A phone number such as [phone] can be thought of as having three  parts: the area code (212), the exchange (767) and the number (8900). Write a program that uses a structure to store these three parts of a phone number separately. Call the structure phone. Create two structure variables of type phone. Initialize one and have the user input a number for the other one. Then display both numbers. The interchange might look like this:
Enter your area code, exchange and number; 415 555 1212

My number is [phone]
Your number is [phone]

Program :- 5

Create two classes DM and DB which store the value of distances. DM stores distances in meters and centimeters and DB in feet and inches. Write a program that can read values for the class objects and add one object of DM with another object of DB.

Use a friend function to carry out the additional operation. The object that stores the result may be a DM object or DB object depending on the units in which the results are required. The display should be in the format of feet and inches or meters and centimeters depending on the object on display.

Create a class Rational which represents a numerical value by two double values-NUMERATOR & DENOMINATOR .Include the following Public member Functions:

• Constructor With no Arguments
• Constructor with two arguments
• Void reduce() tha reduces the rational nuber by eliminating the hightest commom factor between the numeratorand denominator
• Overload +operator to add two rational number.
• Overload >>operator to enable input through cin.
• Overload << operator to enable output through cout

Write a main()  to test all thje functions in the class.

Program :-7

Consider the following class definition 

Class father
{
  Protected: 
     int age;
  public:
     father (int x) {age=x;}

        virtual void iam ()
      {
         Cout<<"I AM THE FATHER, my age is:"};

Derive the two classes son and daughter from the above class and for each, define iam() to write our similar but appropriate messages. you should also define suitable constructors for these classes.

Now write a main() that creates objects of the three and then calls iam() for them. Declare pointer and in each case call iam() through the pointer to demonstrate polymorphism in action.
