I am trying to create a game where a user guesses a number between 1 and 100 using a while loop. But I am getting stuck in an infinite loop. Please help?

Here is what I have:

y=randi(1,100)

prompt= 'guess a value between 1 and 100'

x=input(prompt)

while x<y

disp('guess higher')

(strfind(question,checkExit))

end

while x>y

disp('guess lower')

end

while x==y

disp('you win')

end

So, the computer correctly generates a random value, but when I guess it, it gets stuck in an infite loop of guess lower guess lower guess lower etc. How do I stop this? Thanks!

u can use IF loop to get ur answer......

but in here i think u have to use "BREAK" to stop infinite loop

Let 's try

y=randi(100);

while (1)
    prompt= '\nguess a value between 1 and 100: ';
    x=input(prompt);
    
    if (x<y)
        disp('guess higher');
    elseif (x>y)
       disp('guess lower');
    else
       disp('you win');
       break;
    end
end

This did not work

[Muhammad Waheed AZAM]

you write (1) after the while ? why

[Image Analyst]

1 is always true so that guarantees that you'll get an infinite loop. It will keep asking until the user guesses the exact integer, and then will "break" out of the loop when they do.

@Image Analyst

this code always give 82 number is correct can you help me to improve please

x=randi(100);

y=input(number);

while (1)

number='guess the number between 1 and 100=';

if (y>x)

disp('your guess is higer');

elseif (y<x)

disp('your guess is lower');

else

disp('your guess is correct');

break;

end

end

It should not. See my newly posted answer.

Try this:

trueNumber = randi(100);
userPrompt = 'Guess the number between 1 and 100 : ';
maxGuesses = 7;
numGuesses = 0;
usersGuess = input(userPrompt);
while numGuesses < maxGuesses
    if (usersGuess > trueNumber)
        fprintf('  Your guess of %d is too high.\n', usersGuess);
    elseif (usersGuess < trueNumber)
        fprintf('  Your guess of %d is too low.\n', usersGuess);
    elseif usersGuess < 0
        break; % Quit if they enter a negative number or try more than 6 times.
    else
        fprintf('  Your guess is %d is correct.\n', usersGuess);
        break;
    end
    numGuesses = numGuesses + 1;
    % Let them try again
    userPrompt = sprintf('Attempt #%d.  Guess the number between 1 and 100 : ', numGuesses);
    usersGuess = input(userPrompt);
end

Here you have made some mistakes

1) Gerenating vector instead of single random number

y=randi(1,100);     % Which generates the 1x100 vector not a single random number

Here use single interger random value as

y = randi(100);     % correct way to get a random value between 1, 100(100 is max limit value)

2) While loops

What is the need to use while loop, you can go with if else condition

If necessory, put break keyword in each while loop.

3) comparing single user input value x to y vector in while loop condition checking
