pointer
A variable is a memory address that holds a value. A constant is simply a variable that does not change value.
A pointer is a variable just like any other, so of course it can be assigned a value. However, being a pointer, the value must be a memory address. If you want to assign a value to that memory address rather than the pointer, you must dereference the pointer.
An object is the actual storage space in memory in which some collection of data resides.A reference variable is a variable which refers to the memory location of an object.Look at the pseudocode below:Object obj = new Object();Here obj is the reference variable, and the data to which it refers is the object.
A pointer variable contains the address to some memory location. "Dereferencing" the pointer means getting the value stored at that memory location.
if a variable is of value type memory is allocated on stack memory.. if it is of reference type,memory is allocated on heap memory..
Pointer.
A variable is a named memory address in which a value may be stored and mutated.
A variable is a memory address that holds a value. A constant is simply a variable that does not change value.
A pointer is a variable that stores a memory address and that allows indirect access to the object or value stored at that address.
a pointer is a variable that contains memory location of another variable.the value u assign to the pointers are memory address of other variable.
A pointer is a variable used specifically to store a memory address. We say the variable "points to" the memory address because we can dereference the pointer to access the value stored at that address. The pointer's type determines how that dereferenced value will be interpreted. Being a variable, we can change the stored address and thus change which value we point at. This makes it possible for the same variable to refer to different objects in memory, which includes other pointer variables.
A variable has two associated value with it rvalue and lvalue. 'lvalue' is its location value, that is memory address.
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.

A variable typically consists of a name, a data type, a value, and a memory location where the value is stored. The name is used to reference the variable in the code, the data type defines the type of data the variable can hold, the value is the actual data stored in the variable, and the memory location is where the value is stored in the computer's memory.
