Guess Games The three programs to look at are at: http://cisweb.bristolcc.edu/~pgrocer/CIS122S13/loopsetcJS/guessgameone5.html http://cisweb.bristolcc.edu/~pgrocer/CIS122S13/loopsetcJS/guessgameonegame5.html http://cisweb.bristolcc.edu/~pgrocer/CIS122S13/loopsetcJS/guessgamemulti5.html
start Generate random Guess R = G Got it R > G Low High End I generate a random number and prompt the user for a guess. Then I compare and process. Note this version allows for only one guess. Works best in Firefox
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>JavaScript guess number game</title></head> <body><h1>GUESSING GAME</h1><script type="text/javascript"> var theRanNum = Math.floor(Math.random()*5)+1; document.write(theRanNum); document.write("<br>"); var myGuess = parseInt(window.prompt("Enter your quess")); if (theRanNum == myGuess) { document.write("You got it"); } else { if (theRanNum > myGuess) { document.write("Your guess is to low"); } else { document.write("Your guess is to high"); } }</script></body> </html> Note that I write theRanDum on the screen for testing purposes.
start Generate random Guess R = G Got it R > G Low High End Now I want to set up a loop to continue until the answer is correct. I have decided to use a do...while so the question will be at the bottom. Insert a decision here To continue if the guess was not correct. Loop back to just before the guess.
start Generate random Guess R = G Got it R > G Low High End R != G If the random number and the guess are not equal I go back and guess again. Note that != means not equal to. The do loop I am using will have the do right before the guess so that is the entry point when I loop back.
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>JavaScript guess number game</title></head> <body><h1>GUESS GAME</h1><script type="text/javascript"> var theRanNum = Math.floor(Math.random()*5)+1; document.write(theRanNum); do { document.write("<br>"); var myGuess = parseInt(window.prompt("Enter your quess")); if (theRanNum == myGuess) { document.write("You got it"); } else { if (theRanNum > myGuess) { document.write("Your guess is to low"); } else { document.write("Your guess is to high"); } } } while (theRanNum != myGuess);</script></body></html> Note that the random number is generate once outside the do loop while the user guess is prompted when you look back for another try. I choose a do loop since I always want to do the loop at least once.
start Generate random Guess R = G Got it R > G Low High End R != G Now I need to give the user the opportunity to play again. I will put the question after I get a match. The entry point will come before I generate the random number so that each new game will have a new random number.
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>JavaScript guess number game</title></head> <body><h1>GUESS GAME</h1><script type="text/javascript"> var theRanNum = Math.floor(Math.random()*5)+1; document.write(theRanNum); do { document.write("<br>"); var myGuess = parseInt(window.prompt("Enter your quess")); if (theRanNum == myGuess) { document.write("You got it"); } else { if (theRanNum > myGuess) { document.write("Your guess is to low"); } else { document.write("Your guess is to high"); } } } while (theRanNum != myGuess);</script></body></html> The do will go in here The prompt to ask the user about playing again and the question about the response will go here.
start Generate random Guess R = G Got it R > G Low High End R != G Prompt the user about playing again. The play again do loop comes in before the random number is generated. Play again Again != N
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>JavaScript guess number game</title></head> <body><script type="text/javascript"> var playAgain = "Y"; do { var theRanNum = Math.floor(Math.random()*5)+1; document.write(theRanNum); do { document.write("<br>"); var myGuess = parseInt(window.prompt("Enter your quess")); if (theRanNum == myGuess) { document.write("You got it"); } else { if (theRanNum > myGuess) { document.write("Your guess is to low"); } else { document.write("Your guess is to high"); } } } while (theRanNum != myGuess); playAgain = window.prompt("Do you want to play again, Y or N"); document.write("<br>"); } while (playAgain != "N"); </script> </body> </html>
