I need some help with a mathlab project

Hi, I am making a mathlab project and I can't find any information about hoy can I code the next thing

x=0;

I want to create a loop doing every time x=x+1 ,until I write in the command window

• 'A' : instead of x=x+1 , do x=x+2;
• 'B': instead of x=x+1,do x=x+3
• 'E ' : exit the loop

It is like a loop with 3 states , the state A adding 2 to the counter, the state B adding 3 to the counter, the state C adding 1 to the counter and finally the state E exiting the loop.

I want the loop constantly working, and at the same time while the loop is working I want to be able to write the state in the command window. If I write nothing the loop is still working.

thanks

Use a while loop. Switch-case is more concise.

x = 0; 
while true
    fprintf('x is currently %d \n',x)
    uresp = input('blah blah blah type something: ','s');
    switch lower(uresp)  % does case-sensitivity matter?
        case 'a'
            % do a different thing
        case 'b'
            % do a different thing
        case 'e' 
            break;
        otherwise
            % do the normal thing
    end
end
