Simply put, a pointer is a memory address. It "points" to data at that address. The Data Type of the pointer tells the program how to interpret the data at the address. For example, a character pointer will read the data at the address as a byte and interpret it as a character (like an ASCII character, for instance). A string pointer is just like a character pointer, except that it starts reading characters at the address and keeps going until it encounters a null (a data value of zero). The "string" of characters is interpreted as text. The available data types include just about anything you can imagine. Intrinsic types, structures, functions... in later versions of C, pointers can point to objects.

From where can you get C programming practice questions?
If you want to test/build your skills with pointer math and control flow, check out "The C Puzzle Book" by Alan R. Feuer.
How do you scan values in pointers of C programming?
You do not. A pointer is an opaque value that you do not care what its internal bit value is. You only care that it points to a region of memory that you can do something with. You can scan that region of memory, but not the pointer itself.

What is a ponters in c-programming?
with the help of pointers we able to store the memory location of any variable. In c the pointer variable is use to store the memory location of any variable. The pointer variable is define as a simple variable but in pointer variable use a special "*" character at the left most side of name of pointer variable. If any variable name have * it means it is a pointer variable it hold the memory location of variable.

If d is a pointer variable, then *d is the value stored in the memory address pointed to by d.
What is null point in C programming?
I'm going to go out on a limp here, and guess you mean "Null Pointer." Well, it's a pointer to nothing. For most systems, it's 0, but rather use NULL instead.
