Answers

1.	The pointer must be of the same data type as the variable it is pointing to.
2.	The pointer moves over four bytes.
3.	It points to the address in memory of some variable.
4.	With arrays
5.	Move the pointer over a certain number of bytes.
6.	The address of operator
7.	It is a pointer to a pointer.
8.	So you can pass that function as an argument to other functions
9.	A variable that points to an address in memory, rather than a value
10.	Because pointers contain addresses, multiplication and division do not make sense. If a pointer supported multiplication, the multiplication operation might cause it to point to some memory location that does not exist on your computer.
