Prime Number List Use the isPrime function that you wrote in Programming Challenge 22 in a program that stores a list of all the prime numbers from 1 through 100 in a file. 24. Rock, Paper, Scissors Game Write a program that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows. 1. When the program begins, a random number in the range of 1 through 3 is gener- ated. If the number is 1, then the computer has chosen rock. If the number is 2, then the computer has chosen paper. If the number is 3, then the computer has chosen scissors. (Don't display the computer's choice yet.) 2. The user enters his or her choice of "rock", "paper", or "scissors" at the keyboard. (You can use a menu if you prefer.) 3. The computer's choice is displayed. 4. A winner is selected according to the following rules: If one player chooses rock and the other player chooses scissors, then rock wins. (The rock smashes the scissors.) wins. (Scissors cuts paper.) (Paper wraps rock.) If one player chooses scissors and the other player chooses paper, then scissors If one player chooses paper and the other player chooses rock, then paper wins. e If both players make the same choice, the game must be played again to deter- mine the winner. Be sure to divide the program into functions that perform each major task. 6:38 PM 11/25/2015 Search the web and Windows
