Want this question answered?
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;
A pointer variable contains the address to some memory location. "Dereferencing" the pointer means getting the value stored at that memory location.
a variable should in a programming because as the definition implies it is a named location in the memory where all the data is to be stored
Variable stored in the memory block inside the RAM. whenever we declare a variable it would take space in main memory and consume it's size from RAM.
It depends entirely on what platform you are using. In an embedded environment, for instance global/static variables go into different RAM memory segments depending on whether or not they are initialised. constants are often left in ROM automatic variables are normally placed of the stack of the currently running task but not always.

a variable is a named storage location in a computers memory for holding a peice of information i have computer seince as my major ;)

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.

A variable is a named memory address in which a value may be stored and mutated.

An instance variable is part of an object. Therefore, it gets stored together with the object, on the heap. The heap is the part of memory which is used to store objects.An instance variable is part of an object. Therefore, it gets stored together with the object, on the heap.

When you declare a variable and it's data type in a function, it is stored in the specific space for memory allocated by the variable type identifier known as the "stack."
