The range of a pointer variable is the range of addressable memory. For a 32-bit system there are 2^32 addresses ranging from 0x0 to 0xffffffff. Address 0x0 is a reserved address and is used to indicate a pointer refers to no object in particular (points to null).
Depending on the word-alignment requirements of the architecture, certain addresses may be deemed invalid for a given type. For instance, a 4-byte integer is generally faster to access if it is aligned upon a 4-byte boundary.
yea that's why its called the point FINGER
Answergenerally we use simple pointer, void pointer,null pointer, structure pointer. Answerzero or more (unlimited).
In c a pointer is a variable that points to or references a memory location in which data is stored. Each memory cell in the computer has an address that can be used to access that location so a pointer variable points to a memory location we can access and change the contents of this memory location via the pointer. Pointer declaration A pointer is a variable that contains the memory location of another variable. The syntax is as shown below. You start by specifying the type of data stored in the location identified by the pointer. The asterisk tells the compiler that you are creating a pointer variable. Finally you give the name of the variable. type * variable name Example: int *ptr; float *string;
Pointer to Pointer is a double pointer, denoted by (**). Pointer stores the address of the variable and pointer to pointer stores the address of a pointer variable and syntax can be given as int **ptr2ptr;
pointer
pointer is the variable that holds the address of another variable
Pointer is a variable, A variable that stores the address of another variable. Size of a pointer is 2 bytes.
Pointer is a variable that stores the address of another variable. Since pointer is also akind of variable, thus pointer itself will be stored at a different memory location.
Pointer is a variable that stores the address of another variable . So pointer basically stores the address of another variable and size of pointer can be evaluated by using sizeof operator.
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.
pointer variable B holds base address of B
A pointer is used for pointing to a variable. It contains the address of the variable to which it points
A void pointer variable is a pointer variable (of some type) that is assigned the value zero, meaning it points to address zero. Memory address zero is a reserved address, which means the pointer variable references nothing in particular.
Double (**) is used to denote the double pointer. As we know the pointer stores the address of variable, Double pointer stores the address of any pointer variable. Declaration : int **ptr2Ptr;
