Advantages of pointer in c?
pointer in C have following advantages- 1.Pointer is a very useful concept for creating the important C data structures i.e. linked list, stack, queues and trees, which are very powerful in certain situations. 2.Pointers are very useful when we have to reflect more than one variable change in the calling function after call takes place i.e. though we can not return more than one value from a called function but we can always pass references (pointer variables) to the variables in calling function as parameters to the function.So all the manipulation using these pointer variables will be reflected in called funtion. 3.Pointer provides a lower level view of memory, it adds to our understanding of the things going on in your computer memory.
Difference between pointer to constant and constant pointer?
1. pointer to a constant means you can not change what the pointer points to 2. constant pointer means you can not change the pointer.
What is triple pointer?
Example: int x; -- integer int *px= &x; -- pointer to integer int **ppx= &px; -- pointer to pointer to integer int ***pppx= &ppx; -- pointer to pointer to pointer to integer

A pointer only holds an address information (location) in the memory. if a pointer holds points another pointer then it is a pointer to an other pointer. Pointer holds an address in the memory so in that address there is an other location information that shows another location.
What is the difference between pointer variable and simple variable What are the advantages of pointer variable?
normal variable stores a value of the given datatype where as the pointer variable stores the address of a variable. for example int n=10; int *p; p=&n; here p is a pointer variable and n is a normal variable.p stores the address of n where as n stores an integer value. *p prints the value of n,p prints the address of n.
What is pointer of pointer?

Define pointer to pointer in c?
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;
Why is double pointer used?
Double pointer is a pointer to a pointer. So you can work with the double pointer as you work with a single one.Or you might mean 'pointer to double', eg:void clear_double (double *dp){*dp = 0;}
C program pointers to pointers examples?
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;
