Write a program in C++ that can perform encryption and decryption using an arbitrary substitution cipher. In this case, the encrpyion array is a random shuffling of the letters in the alphabet. Your program should generate a random encryption array, its corresponding decryption array, and use these to encode and decode the message

Write a program in C that create a 3-by-5 array. All elements in the array are random integer numbers between 1 and 100. Then, put all elements of the two-dimensional array into a one-dimensional array. Finally, calculate the mean value and the median value of 1-D array. Print out the 2-D array, original 1-D array, sorted 1-D array, and the mean value and the median value of 1-D array.

Write a C++ program using classes and recursion functions to covert a number in a given base (the user enters the base - from 2 to 9) to a decimal number. The algorithm states that each successive digit in the number is multiplied by the base raised to the power corresponding to its position in the number. The low-order digit is in position 0. We sum together all of these products to get the decimal value. For example, in binary- base 2, if we have the binary number 111001, we convert it to decimal as follows: 1x25 + 1x2* + 1x2³ + 0x2²+ 0x2² + 1x2º = 57 For a base 5 number, 14230: 1x5 + 4x53 + 2x52 + 3x5+ Ox5° = 1190 Validate your input. You should check for invalid digits and provide an informative error message to the user. This program requires you to use a recursive function for the conversion to decimal. Failure to do that will result in no points awarded.

Write a program that reads movie data from a CSV (comma separated values) file and output the data in a formatted table. The program first reads the name of the CSV file from the user. The program then reads the CSV file and outputs the contents according to the following requirements: • Each row contains the title, rating, and all showtimes of a unique movie. • A space is placed before and after each vertical separator (I) in each row. • Column 1 displays the movie titles and is left justified with a minimum of 44 characters. . If the movie title has more than 44 characters, output the first 44 characters only. • Column 2 displays the movie ratings and is right justified with a minimum of 5 characters. • Column 3 displays all the showtimes of the same movie, separated by a space. Each row of the CSV file contains the showtime, title, and rating of a movie. Assume data of the same movie are grouped in consecutive rows. Ex: If the input of the program is: movies.csv and the contents of…
