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!

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

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
