How do I write a number and Letter in the same line?

values = {'Enter a value that is equal to or greater than 0 but equal to or less than 100:','Enter a 2nd value that is equal to or greater than 0 but equal to or less than 100:'};
values = inputdlg(values)
values = str2double(values)
n = mean(values)
if n >= 91
  grade='A'
elseif n >= 81
  grade='B'
elseif n >= 71
  grade='C'
elseif n >= 61
  grade='D'
else
  grade='F'
end
k = n + grade
disp(k)

I need to write n and grade on the same line, but when this runs, instead of displaying the value of n, it displays a seemingly random symbol or number with the grade letter attached.

example: If I enter 88 & 67 it makes k = 'MC', the values 100 & 20 make k = '<F'.

Please help.

You can use:

fprintf('grade=%f, %s\n',n, grade);

That worked! Thank you so much!
