File Encryption and Decryption
Write a
map<char, char> codes =
{ {‘A’, ‘%’}{‘a’, ‘9’}, {‘B’, ‘@’}, {‘b’ , ‘#'}, etc...};
Using this example, the letter ‘A’ would be assigned the symbol %, the letter ‘a’ would be assigned the number 9, the letter ‘B’ would be assigned the symbol @, and so forth. The program should open a specified text file, read its contents, then use the map to write an encrypted version of the file’s contents to a second file. Each character in the second file should contain the code for the corresponding character in the first file. Write a second program that opens an encrypted file and displays its decrypted contents on the screen.

- Assignment 5C: Level Map Creator. There are a variety of ways that game developers store their level layouts. One simple method is to associate level elements with certain symbols, and then storing them in a 2D grid inside a text file. We will use our knowledge of 2D arrays to create a very simple Level Map Creator tool. The program should prompt the user to enter a width and height for the level. Then it should initialize a 2D array and fill every element with the *" symbol. Afterwards, the user should be given the following options via a menu: 1. Clear Level 2. Add Platform Prompt the user to enter a starting point and length for the Re-initialize the 2D array and fill every element with the "** symbol. horizontal platform. Replace those elements in the 2D array with the "=" symbol. If the length is longer than the number of columns |(or out of bounds), notify the user that this is not possible. Prompt the user to enter a column and row index.

A poker hand can be stored as an array of five struct cards. A flush is a hand that contains five cards, all of the same suit. Write a function that returns 1, if the poker hand passed to it has five cards of the same suit, and 0 otherwise. int isFlush(struct card hand[]); int isFlush(struct card hand[]) {arrow_forwardproducts := [5] string {"bread", "milk", "eggs", "butter", "sugar"} price := [5] float64{1.29, 3.75, 3.33, 2.97, 5.28} use a "counting loop" to print the products with their prices example: bread: $1.29 milk: $3.75 eggs: $3.33 butter: $2.97 sugar: $5.28arrow_forward
