Use CurrentKey 'Enter'

Otherwise, char(10)

MATLAB: Allowing backspace only on the last item entered

string = '';
last_was_bs = false;
while true
  char = GetChar;
  switch (abs(char))
      case {13, 3, 10}
          % ctrl-C, enter, or return
          break;
          case 8
            if ~last_was_bs
              % backspace
              if ~isempty(string)
                  string = string(1:length(string)-1);
              end
            end
            last_was_bs = true;
          otherwise
              string = [string, char ' '];
              last_was_bs = false;
      end

However, I don't think you are going to find this very suitable. The extra space that is inserted after every character increases the length of the string, and would thus be what was trimmed out by the first backspace. In order to be able to actually remove the last character typed, the user needs to be able to type at least two backspaces. Unless, that is, the extra space was not added.

It is poor programming practice to name a variable "char", as that interferes with using the MATLAB char() function.

MATLAB: Equivalent of “Enter”

Add '\n' at the end of fprintf. This gives control to the next line.

   fprintf('The result is %d\n',y) ;
   x=input('Enter x:')
