Part III: Problem Solving Questions [40 Marks]

Note: Provide a copy of the code and screen shot for the output in the solutions’

1. Write a program to create two multidimensional arrays of same size. Accept value from user and store them in first array. Now copy all the elements of first array into second array and print second array
[15 Marks]

2. Write a C# application that asks the user to input the required data to implement the four methods below:
(Use Method Overloading to write the methods)
a. Method Area that take as input an int value ‘side’, calculates the area of a square, and displays it.
b. Method Area that take as input an int value ‘L’ and an int value ‘B’, calculates the area of a rectangle, and displays it.
c. Method Area that takes as input a double value ‘R’, calculates the area of a circle, and displays it.
d. Method Area that take as input a double value ‘B’, and a double value ‘H’, calculates the area of a triangle, and displays it.
