Note that having an underscore prefix on a global symbol is undefined behavior (7.1.3). You can easily fix this by marking _total_allocated as static.

Do you mean implementation-defined?

sizeof(char) is 1 by definition.

All the images are gone.

So now it's impossible to answer?

The name of the function is the same as a function provided by the C library.

The picture provided with the code does not display. The expected input, output, and algorithm are not shown. The answer is in the full test suite, and is shown when an incorrect answer is inputted.

I've just posted an obfuscated C solution. Try to understand it!

It works for me too, now. I guess it was just a random bug. It was using the foo() function when the bug occured. It also seemed to be testing for multiplication.

When I try to submit a result or run sample tests, this Kata gives me the "Missing language" error. I'm using C.
