**Student answer is**

function result = operation(a,b)

result=a*b+max(a,b);

end

result=a*b+max(a,b);

end

**Is the closing end necessary? Can the student answer be just**

function result = operation(a,b)

result=a*b+max(a,b);

result=a*b+max(a,b);

Besides CodeRunner, I know both kinds of examples, such as

- The closing end is not necessary in Matlab.
- Closing end is necessary when defining functions in Octave command line.
