Lab 2 Assignment

[Dave077]

Hello Alice Community,

After working on Lab2 and modifying the world to work properly I will share with you my ideas. I first built an If / Else loop, but noticed it only executed 1 time. Then changed to a While Loop, while the answer to Run again? was Yes, to keep looping program, and it worked. I decided to run statements before the While Loop to have the world start playing and then go into the loop.

I look forward to your comments.

Warm Regards,

David

Hi David,
Starting statements before the while loop is one way to go. After re-evaluating my submission for this project, I chose to run all of my statements within my while loop. In fact, to have better error control, I used a while loop within a while loop as follows:

Think of the variables count1 and count2 as on/off switches, 1=on, 2=off. Except these variables kill or start the appropriate while loop.

count1 = 1;
count2 = 2;
spins = 1;
playAgain = default string;

// Start of main loop

while count1 == 1
spins = ask user for a number;

if spins <= 10

character spins around
// Kill main loop
count1 == 2
// Start loop 2
count2 == 1

else if spins > 10

character says "Number is too high"

// Start of loop 2

while count2 == 1
playAgain = "Would you like to play again?";

if playAgain == yes, Yes, or YES

// Restart main loop
count1 == 1
// Kill loop 2
count2 == 2

else if playAgain == no, No, or NO

character says "goodbye!"
// Kill both loops
count == 2
count == 2

else

character says "I don't understand that answer. Please try again."

// End of loop 2

// End of main loop

This way I was able to control the program in case the user input a number higher than 10 and something other than yes, Yes, YES, or no, No, NO. There are other error controls I could implement such as if the user inputs something other than a number or a negative number ... but this will do for now.

Of course this isn't the only way to do this, but I felt my code was cleaner and easier to work with than trying to nest a whole bunch of if/else statements in one while loop.
