Please help me to check what did I do wrong here, thank you! it's a matlab question

Question 2: consider the following scheme which maps an integer quiz grade to a corresponding letter grade: 9 or 10 is an A 8 is a 'B' 7 is a 'C' 6 is a 'D' Anything below 6 is an 'F' Write a function called letgrade which receives an integer quiz grade and returns a corresponding letter as per the scheme above. Also the function returns the letter X if the quiz grade is not valid. This can be implemented with if else statements.

Explanation / Answer

You have missed the brackets in the conditional statements which may cause an error in the code. Another mistake is that you have missed the semicolon in this statement=> b=('B');

Here is the corrected code,

function b=letgrade(x)

if (x>=9)&&(x<=10)

b=('A');

elseif (x==8)

b=('B');

elseif (x==7)

b=('C');

elseif (x==6)

b=('D');

elseif (x<6)

b=('F');

else

b=('X');

end

end
