Following usual C convention for declarations, declaration follows use, and the * in a pointer is written on the pointer, indicating dereferencing.For example, in the declaration int *ptr, the dereferenced form *ptr is an int, while the reference form ptr is a pointer to an int.Thus const modifies the name to its right.
