Write a C# code that contains a two dimensional integer array which has the size 3x4; • A random number (between 25 and 75) will be assigned to each element of the array. Elements will be shown in matrix format at Console window. • The transpose of the array will be written to the "myFile.txt" file. An example after running the program The content of myFile.txt | myFile - Notepad File Edit Format View Help Console window C.

Build Brothers company in C A civil engineering company called Build Brothers has approached you to write a program to help some of their employees with getting their job quicker specially when it comes to calculating different equations in their construction projects. Currently, they use the following PDF to perform all their calculations: http://www.madison-lake.k12.oh.us/userfiles/680/Classes/16192/IED-Review%20Engineering%20Formula%20Sheet.pdf They are willing to develop a small software to calculate all the functions and calculations in the above cheat sheet. They have made this decision to reduce inherent human errors during calculation and improve efficiency. They think that these can be achieved by an “advanced calculator” that allows a user to choose an equation, provide the inputs, and calculate the outputs. Before the company invests on the final product, the have agreed on developing a proof-of-concept first. The idea is that your solution will ‘prove’ that a better…

Caesars Cypher in C programming language How do you program an encryption and decryption for a Caesars Cypher that covers all the possible ASCII characters? In this there should be a shift over K = 5 but the example below is K = 3. This should result in actual character and not the control ASCII represenations. For example: >>> $ encrypt(I have a key)N%mf{j%f%pj~>>> $ encrypt(see me at 3)xjj%rj%fy%8>>> $ decrpyt(|jfw%ns%gqzj)wear in blue Assume that the text parsing method has been succesful and it's the encryption/decryption of the char array that needs to be factored. Formula Encryption -> C = E(k, P) = (P + k) (mod 26) Decryption -> P = D(k, C) = (C - k) (mod 26) Where k = 5
