diagonal = true;
for  index = 1:1 
         disp('   straight , sideways , diagonal')
    x = input(' Which way does checker pieces move? ','s');
    if x ~= diagonal
       disp('False, Start Over!')
        return
      elseif x == diagonal
           disp('Correct!')
       break
    end
end
%% It should display correct when put in diagonal???

Hi Kalpha.mc,

In the first line of your code snippet, you are defining a boolean variable 'diagonal' and set it to true.

But in the if/else conditional you are checking if the value of the variable x is diagonal or not.

For comparing strings you can use the strcmp() function.

Below is the working code of what you intended to achieve.

for  index = 1:1 
    disp('straight , sideways , diagonal')
    x = input('Which way does checker pieces move? ','s');
    if strcmp(x,'diagonal')
        disp('Correct!');  
        break
    else
        disp('False, Start Over!');
        return; 
    end
end
