Hi, I was given this assignment and wasn't sure how to set up the loop.
"Write a "while" loop that continues generating a random number x until x is less than 0.01. Keep track of how many iterations of the loop occurred. Then, use "fprintf" to print the final iteration count to the command window, along with the last value of x."
Thanks.

Try this - it's a start:
loopCounter = 0;
maxIterations = 10000; % Failsafe. A number of iterations which you think you should never exceed.
x = inf; % Initialize
while x >= 0.01 && loopCounter < maxIterations
% Get new x (code for you to do...)
% Increment loop counter
loopCounter = loopCounter + 1;
end
fprintf('.......to do', ....)
The failsafe is not strictly required but you should always use one. I can't tell you how many times people write in and say they have a hung or infinite loop and it could be avoided if they had just used a failsafe.

Inspite of the vivid discussion, I'm the only one who voted for this useful answer. Because it matchs the question without posting a solution of a homework question, I select it as accepted answer.
