A magic square with n order is comprised of n^2 numbers(from 1 to n^2).Sums of each row,each column and its diagonal sums are
the same. The constant sum in every row,column,and diagonal is called magic constant, M,where:
M=n(n^2+1)/2
In this project,you are required to design a programme called Magic Square for Odd Order. The programme should prompt user for
any valid odd integer, n, and produce a magic square with size n x n.

Create a 2-dimensional (3 x 3) integer array which contains 9 random numbers ranged from 0 to 100. For each number, determine whether the number is a prime number or not. You should define a method to test whether a number is prime or not. A prime number (n) meets the following requirements:
1.n must be larger than 1..
2.If n is greater than 1, then start dividing by 2, 3, …, n-1 and check the remainder. If none of remainder equals to 0, then n is a prime number. Otherwise, it is not..

Your programme should:
1.Print all elements in 3 rows.
2.Print the total number of prime numbers..
3.Print all location(s) of prime number(s) and their values (if there is any).

Which of the following C# code lines is valid?
byte x = 2.0;
byte x = (2 + 3);
byte x = (byte)(2.0 + 3);
byte x = (byte)(10 - 11);

Write an XOR cipher program using the
C programming language.
the program must accept as input from the user a value between 0 and 255 to be used as the
secret key, the name of the input file and the name of the output file. No line in the input file
should contain more than 4096 characters.
After the user would have provided their secret key, the program should read and perform an
XOR cipher on the contents of the input file and write the result to the output file.
If the input file has already been encrypted and the identical secret key that was used to
perform the initial encryption is provided, then the contents of the output file should be
deciphered into its original plain text.

design and implement a billing management system application that handles financial transactions for a small bank.you should take into consideration defining customers. A withdrawal or deposit method can be performed to this account so we can also view an account statement with the last operation made based om date selected. the bank would also like to keep track of the total number of available customers, the most active customer (the one with height number of transactions), the total funds available and the total expenses (withdrawals)made.

ETECWorld is a medium company, which is involved in creating architectural
designs for building such as bridges, hospitals and education institutes. While
making the architectural designs the architects working in ETECWorld need to
calculate the area of different shapes such as rectangle, circle and squares. Till
now these architects have been calculating areas manually using calculator for
complex calculations. Manual calculation of different shapes is time consuming.
As a result the efficiency of the architects working in ETECWorld has decreased
considerable. How can ETECWorld solve this problem?

NB: Use your C# skills to design a solution to this problem
