The assignment targets plain C language, not C++. Therefore, you do not 
have standard C++ library available.

By the way, the assignment does not require any functions from standard 
library (libc). The only exception is putchar for simple_printf and 
malloc/free for the frequencies.

Have you looked at the provided tests? They document the API too if the 
text is not clear enough.

Hope this helps.
