You have to implement a typeof unary operation that shall yield the type of its argument as a string.

It should work for the following types :

int
float
double
void*
char*
int*
const int*
void (*) (void)
struct timespec // defined in <time.h>
div_t           // defined in <stdlib.h>

If the argument is of any other type, the result should be "unknown type".

Note : Pay attention to the way your code is run in the sample tests.
