If statements inside while loop

Hi all,

im trying to write a script that has a while loop with conditional statements.

I am trying incoperate my if statements into the while loop so that if a input is above or below 20 and 0 it will display message.

i am not sure where the if statements are meant to be, inside the loop or outside.

here is my code an help would be appreciated.

clear all;
n=input('Which multiplication table? :');
n=input(prompt);
min_integer=0;
max_integer=20;



i=1;
while(i<=12)
    if n < 0
    message = 'Please enter number from 0 to 20.';
elseif n > 20
    message = 'Please enter number from 0 to 20.';
end
    fprintf('%dx%d=%d \n',n,i,n*i);
    i=i+1;
    
end

Thanks

Like this, if necessary.

% set up parameters and use them
max_k = 12;
min_input=0;
max_input=20;

nisbad = true;
while nisbad
    % explain the inputs to the user
    % nobody can guess what the limits are unless you tell them
	disp('Which multiplication table?');
	n=input(sprintf('Please enter number from %d to %d: ',min_input,max_input));
	nisbad = n<min_input || n>max_input;
end

for k = 1:max_k 
	fprintf('%dx%d=%d \n',n,k,n*k);
end

I could say something about this style of bad design taught by introductory assignments, but I've said it enough times to know that it doesn't matter.

im confused by what you mean by your last comment

Don't take that the wrong way. I'm assuming this was homework. I'm just at odds with certain things instructors ask students to do in their homework assignments. I had to do the same things too.
