Code Input and Output

Fail

h = counter; assert(isequal(h(), 1)) assert(isequal(h(), 2)) assert(isequal(h(), 3)) assert(isequal(h(), 4)) assert(isequal(h(), 5))

h = 1

Out of memory. The likely cause is an infinite recursion within the program. Error in counter (line 10) h = h + counter()

Pass

code = fileread('counter.m'); assert(isempty(strfind(code, 'persistent')));
