Write a C++ program that writes a PGM out to a text file. Make your image 40 columns by 20 rows. Set the maxval to 255. Let each pixel be 4 more than the previous pixel; let each row be 10 more than t
Question 1: What is the difference between link and end-to-end encryption? Question 2: List ways in which secret keys can be distributed to two communicating parties.
Question 1: What are the two general approaches to attacking a cipher? Question 2: Why is the middle portion of 3DES a decryption rather than an encryption?
With the ECB mode, if there is an error in a block of the transmitted cipher text, only the corresporrding plaintext block is affected. However, in the CBC mode, this error propagates.

Print a simple loan payment table for 12 months showing two columns: the month number and the remaining balance at the end of the month after payment. The initial loan will be $1000 and the payment wi
Question 1: Create a package cs2302. The class files Point.java and Line.java must be in the package. Question 2: Create the package cs2302 testing. The test file Tests.java must be in the package.
Create an fstream to a binary file that you can both write to and read from. Write 5 objects of your class to your binary file. Then see if you can read them all back in order and print them to the sc
Write a program in C that lets a user manipulate bits individually in a 4-byte variable. The program should begin with all bits having a value of zero. The program should enter a loop where it prints
Design a circuit with output f and inputs x1, x0, y1, and y0. Let X=x1x0 and Y=y1y0 represent two 2-digit binary numbers. The output f should be 1 if the numbers represented by X and Y by X and Y are
Question 1: Implement both encryption AND decryption of the Viennese cipher with 26 English letters and 1 space character "_" in its tableau. You may use any major programming languages. Question 2: A
Write a program that generates all prime numbers between 2 and 1000, using the Sieve of Eratosthenes method. You can find many articles that describe the method for finding primes in this manner on th
Design an algorithm and accompanying pseudo code that will prompt a user for three numbers, accept that input, and sort it into ascending sequence, and then output the values to the screen.
Question 1: Calculate the memory requirements of the two data structures. Question 2: Hence explain the advantage of one data structure over the other.
A program is maintaining two data structures (a) A linked-list which has an integer field and (b) An array of integers. The same numbers appear in ascending order in both data structures.
Write a recursive definition for integer division. Then write a recursive method for division that accepts two integers and returns their integer quotient.
Draw the hierarchy chart and design the logic for a program that calculates service charges for Hazel’s Housecleaning service. The program contains housekeeping detail loop, and end-of-job modul
One characteristic of programming languages that varies widely from language to language is how parameters are passed. Among ALGOL, Pascal, Ada, C, C++, Java, and C#, no two languages pass parameters
