MATLAB: How can i write a matlab code to a multple choice question having multiple answers?? say i have to pick out A,B,C,E but excluding D. so far i have this below…

multiple answers

n=[A,B,C,E];
for n=input('Enter your answers:');
switch (n);
       case 'D'; case 'd'; 
            if n=='D'||n=='d'
            disp('wrong answer. Try again please');
            fprintf('Your scored mark is zero(0)\n');
            break;
            end
          if n=='A'||n=='a'&& n=='B'||n=='b'&& n=='C'||n=='c'&& n=='E'||n=='e';
            disp('correct answers,congratulations!');
            break;
          end
     end
end

Best Answer

answer = 'n'
while(answer ~= 'd')
    in = input('Get input: ','s');
    switch lower(in)
        case 'a'
            disp('Right')
            answer = 'a';
        case 'b'        
            disp('Right')
             answer = 'b';
        case 'c'
            disp('Right')
             answer = 'c';
        case 'd'
            disp('Wrong')
             answer = 'd';
        case 'e'
            disp('Right')
             answer = 'e';
        otherwise
            disp('Invalid choice')
             answer = 'na';
    end
end
You can put a function in the correct cases instead of the disp('Right')answer ='a' so it runs the same function if you wanted to as well
