What is a pointer value and address?

[phaneendra_vemuri]

* represents the value in the address and address is ..........address of the variable

[TAM]

pointer value is the value stored in a pointer i.e an address of a variable
Address - itself gives the memory location which contain an value of any type

[gouriproutray]

basic thing is like other variable (....like int a here a is integer type variable which can hold an integer value.. when we define int a.. compiler allocates a memory 2 or 4 bytes and name it as a..when we assign value it places that value in that memory)
pointer is also a variable.the same thing the compiler does for pointer also..but the difference pointer and a normal variable is the pointer holds the address of other variable of its type..when we ask what is the value of a then its the value we have assigned to it..same thing when we ask what is the value of pointer then its the value we have assigned to it, but here the value is the address of other variable of its type..coming to address like other variable has some memory address..so since pointer is also a variable it also takes some address from memory

pointer is a variable that hold the address of other variable.
it should be declared as
data type *pt_name
eg
int *p;//declare pointer p
p=&a;//address of variable a
v=*p;//v have tha value at address p
