Help making a program !

Write a program which helps a pupil to learn 9×9 multiplication table. The program imposes random questions, for instance, “5 * 3 = ”, “2 * 6 = ”, “3 * 8 = ” etc. and the user should enter an answer. If the answer is not correct the program should display an error message and provide a right answer. The program has 5 different levels of difficulties which correspond to a number of seconds the use has to enter an answer. If the user does not manage to answer within the limited time, the program generates an error message.

-This is to make the table :

N = randi(12) 
for i = 0:length(N); 
    fi(i)=9*N(i); 
end
% With out loop
N = 1:10 ;
fi = 9*N ;

-The diffrent messages:

msgbox('Right answer')
errodlg('Right answer is.....',Error')

I have problem to make random Q, make pepole write the answer and get if that rigt or wrong and make the program 5 diffrent level.

Here is start:

• use input to ask the user to enter some number
• use if..else..end statements to check if the answer is correct or not
• msgbox as you mentioned above
• pause(0.5) can be used to wait for the answer (0.5 seconds)

How to exit the input() command after a specific number of seconds? pause() will not be helpful.

i agree. Took me 3 days without success. How to resolve?

darova, there is no good way to timeout on input() function. Some undocumented functions can be used to interrupt input(), but they also throw an error, and I couldn't figure out how to suppress the error message. The only way which makes sense to timeout on user input is to use inputdlg() with a timer as described here: https://www.mathworks.com/matlabcentral/answers/96229-how-can-i-have-a-dialog-box-or-user-prompt-with-a-time-out-period
