  Write a program using class ‘Rectangle’ to compute the area and perimeter of rectangle. The Class rectangle should have the following members:

·        Two data members’ length and width.

·        One member function ‘setData’ to assign values to data members ‘length’ & ‘width’. It should also verify that length and width between 0.0 and 25.0 

·        One member function ‘area’ to compute and print the area of rectangle.

Area =length * width

·        One member function ‘perimeter’ to compute and print the perimeter of rectangle.

Perimeter =2*(length * width)

Write a program using class ‘FindEnergy’ to compute the Potential Energy and kinetic Energy of an object. The class FindEnergy should have following members.

• Four data members mass, height, velocity and gravity (9.8m/s2) take gravity as Constant.

• One member function ‘setInputData’ to assign values to data members.

• One member function ‘potentialEnergy’ to compute. And return the Potential Energy.

HINT: P.E=mgh

• One member function ‘kineticEnergy’ to compute. And return the Kinetic Energy.

HINT: K.E=1/2 mv2

Give an example of a while loop, then provide the equivalent do-while loop and for loop. Then give a different example of a do-while loop, along with the equivalent while loop and for loop. Finally, give an example of a for loop, along with the equivalent while loop and do-while loop. Use your examples to illustrate the advantages and disadvantages of each looping structure, and describe those advantages and disadvantages.

In the character class main method, implement code to demonstrate applying the above classes as follows: (a) Declare a Character reference variable and create one of your custom character objects to store in it (b) Create an Item object for use by the character (c) Simulate the character receiving and using the item by calling character class method.
