USE C++: Encryption and Decryption are two cryptographic techniques. Encryption is used to transform text to meaningless characters, and decryption is used to transform meaningless characters into meaningful text. The algorithm that does the encryption is called a cipher. A simple encryption algorithm is Caesar cipher, which works as follows: replace each clear text letter with a letter chosen to be n places later in the alphabet. The number of places, n, is called the cipher key. For example, if the cipher key is 3, the clear text“HELLO THERE” becomes “KHOOR WKHUH”.Here, we restrict ourselves to encrypting/decrypting digits (0...9), lowercase, and uppercase alphabetic characters. As you know from the ASCII table, the set of these characters correspond to the integers 48to 122.Hint: The following formula can be used to encrypt a character C using the Caesar cipher algorithm: E = (C –‘0’ + k) % 75+ ‘0’ [where k is the cipher key]You need to figure out the formula for decrypting text on your own.NOTE: Use cipher key = 7.Write a C++ program for encrypting and decrypting a given string. Since this program performs two different functionalities (encryption and decryption), prompt the user to select the type of cryptographic technique as shown below: Welcome to Cryptographic Techniques ProgramPlease enter your selection:1. Encrypt2. DecryptWhen the user selects 1 or 2, s/he will be asked to specify an input and output message. Here is an example: Assume that the user enters the following message: HOW ARE YOU DOING? If the user selects to encrypt the message (i.e. option 1), the program will encrypt the original message and outputs an encrypted text. If the user selects to decrypt a message (i.e. option 2), the program will decrypt the encrypted text and outputs the decrypted text on the screen. The program should give the user the option of whether to continue with encrypting/decrypting messages (i.e. entering the letter ‘C’) or exit the program (i.e. entering the letter‘E’).

a. F = WXYZ(WXYZ’ + WX’YZ + W’XYZ + WXY’Z)

Provide the optimal Solution to the problems below using java code and include Time Complexity Analysis!

1. Peaks and Valleys

In an Array of integers, a “peak” is an element which is greater than or equal to the adjacent integers and a “valley” is an element which is less than or equal to the adjacent integers. For example, the array {5, 8, 6, 2, 3, 4, 6}, {8, 6} are peaks and {5, 2} are valleys. Give an array of integers, sort the array into an alternating sequence of peaks and valleys.

EXAMPLE

INPUT:

                                {5, 3, 1, 2, 3}

                OUTPUT:

{5, 1, 3, 2, 3}

2. Build Order

You are given a list of projects and a list of dependencies (Which is a list of pairs of projects, where the second project is dependent on the first project). All of a project’s dependencies must be built before the project is. Find a build order that will allow the projects to be built. If there is no valid build order, return an error.

EXAMPLE

                INPUT:

                                Projects: a, b, c, d, e, f

                                Dependencies: (a, d), (f ,b), (b, d), (f, a), (d, c)

                OUTPUT:

f, e, a, b, d, c

(I need java code with explanation of algorithms and time complexity)

Assume that you are given a task to design a system for a vehicular network (or any cloud computing system). Briefly discuss security requirements for such a system. Outline a security architecture that could achieve the specified security goals in the scenario. You must include in your discussion of the security limitations of your approach. Note that this is intended to be an open-ended problem and your alternative security architecture may or may not exist as a specific product or system, so you are expected to think creatively about this solution. It is likely that you will need to undertake some research to assist in answering this part of the problem.

3) Consider the following IA32 assembly language code fragment. Assume that a, b and c are integer variables declared in the data segment.

                        movl    a, %eax
                        movl    b, %ebx
                        cmpl    %ebx, %eax
                        jge     L1
                        movl    %eax, %ecx
                        jmp     L2 
                L1:     movl    %ebx, %ecx
                L2:     movl    %ecx, c 

Write the C code which is equivalent to the above assembly language code. You don't need to include the variable declarations, a function or anything like that, just show the 1 to 4 lines of code in C that express what the above assembly code is doing:

An independent testing team is beneficial for test quality and comprehensiveness. Why?

C++ On linux

Write a C++ program using the IPC. Declare two variables a=5 and b=6 in writer process. Now their product (a*b) will be communicated to the reader process along with your name. The reader process will now calculate the square root of the number and display it along with your name.

2) Draw a line between each of the IA32 assembler routines on the left and its equivalent C function on the right. (If there is no matching C function, do not draw a line.):

}

int fun4(int a, int b)
{
   if (a < b)
      return a;
   else

A:     .long 10, 20, 30, 40, 50
       .text
main: <code>

OBJECT ORIENTED PROGRAMMING

Design two grid based games or two block based games in c++

In some cases, the bulk of the project lies in producing a nice user interface, probably using the FLTK graphical library, while the algorithmic content is quite simple. In other cases, the bulk of the work is in devising and implementing the algorithms. Some projects are more difficult than others, but a good policy is to choose one which allows extensibility if you have more time, or a suitable half-way stopping point if it proves to be difficult.

1. Grid based games, ranging from the simple such as Noughts and Crosses through more complex games such as Minesweeper and Battleships. See Levy Computer Gamesmanship pp. 30-39
2. Block based games, such as Snake or Tetris.
3. You can design hangman, pong , tic tac toe

Tool: Dev++, Visual Studio or any of your choice.
