Analysis of Stone and Paper Game - Assignment Example

Analysis of Stone and Paper Game This program enables the user to play the stone/paper/scissors game against the computer. When this game is playedbetween two people, the players simultaneously choose one object (stone, paper, or scissors). After a count of three, the players make either a fist for a stone, a flat hand for paper, or a ’V’ with two fingers to represent scissors. There is then a matrix for deciding who wins that round: -------- Player 1’s choices-------- Player1‘s choices Player 2‘s choices Stone Paper Scissors Stone Same choice; no one wins Paper (player 1) wins because paper surrounds stone. Stone (player 2) wins because stone smashes scissors. Paper Paper (player 2) wins because paper surrounds stone. Same choice; no one wins Scissors (player 1) wins because scissors cuts paper. Scissors Stone (player 1) wins because stone smashes scissors. Scissors (player 2) wins because scissors cuts paper. Same choice; no one wins Main algorithm for the program: while loop = ‘y’ do prompt the user for how many rounds they want to play initialize the variables sb1 and sb2 to 0 (counts number of wins) for the number of rounds chosen, prompt the user for their choice of paper/scissors/stone = ch use the rand function to get a random number between 0-2 (for the computer’s choice of paper/scissors/stone; store in randomNo) call function chk1 to find who wins print the results of how many games were won (sb1 and sb2) prompt user to play again (store in “loop” variable; if loop not equal to ‘y‘ or ‘Y‘ then while loop is finished) end while loop Algorithm for the function chk1: if user chose paper (variable ch=1) then if the computer chose paper (variable randomNo = 0) then print statement that no one wins (since both made the same choice) if the computer chose scissors (randomNo=1) then print statement that computer wins since scissors cuts paper change count of computer wins (increment variable “sb2”) end if if the computer chose stone (variable randomNo=2) then print statement that the user wins since paper surrounds stone change count of user wins (increment variable “sb1”) end if end if (ch=1) if user chose scissors (variable ch=2) then if the computer chose paper (variable randomNo = 0) then print statement that the user wins since scissors cuts paper change count of user wins (increment variable “sb1”) end if if the computer chose scissors (randomNo=1) then print statement that no one wins (since both made the same choice) if the computer chose stone (variable randomNo=2) then print statement that the computer wins since stone smashes scissors change count of computer wins (increment variable “sb2”) end if end if (ch=2) if user chose stone (variable ch=3) then if the computer chose paper (variable randomNo = 0) then print statement that the computer wins since paper surrounds stone change count of computer wins (increment variable “sb2”) end if if the computer chose scissors (randomNo=1) then print statement that the user wins since stone smashes scissors change count of user wins (increment variable “sb1”) end if if the computer chose stone (variable randomNo=2) then print statement that no one wins (since both made the same choice) end if (ch=3) end function chk1 Flowcharts are as follows: The data storage requirements are as follows: a variable must hold the user’s choice of paper/scissors/stone; another variable must hold the computer’s choice of paper/scissors/stone. If these three choices are represented as integers, then the variables can be integers called “ch” and “randomNo”. Another integer can hold the number of times the user wants to play, this integer is called “roundsnomber”. Integers “sb1” and “sb2” can hold the number of times the user or computer wins. The program detects if the player wants to continue play by reading a character from the keyboard, this is a type char variable called “loop”. The function “chk1” handles the analysis of who wins, by using the logic of the matrix above. Function “chk1” goes over every possible case of combinations of choices that the user and computer may make. This way the main program is mainly free to handle input and output, and make the random choices of the computer. Code for the program (first version) is as follows: #include #include #include #include int randomNo; int ch, sb1, sb2; void chk1(void); void main (void) { char loop=y; int roundsnomber; randomize(); printf("Welcome to the scissors, paper, stone game \n\n\n"); do { printf("How many rounds would you like to play for?"); scanf("%i", &roundsnomber); printf("\n\nGame started....\n\n\n"); sb1=0;sb2=0; for (int i = 1; i Read More
