Whenever a variable is declared the computer allocates that variable somewhere in the memory. Reduce the length and complexity of a program.Pointers enable us to access a variable that defined outside the function.Pointers deals with this allocation of the memory. Thus it means how the data is stored in memory. If we declare an integer array of size 10 we require 2(size of an integer) * 10 (the array size) bytes which is 10 * 2 =20 bytes. But in the case of arrays we want to calculate the size by size of data item * number of allocated size. For example, a character will be stored in 1 byte of memory where as an integer requires two contiguous bytes, but a floating-point number usually requires four contiguous bytes. The size of data or the number of memory cells required to store a data item depends on the type of the data item we are used. Each byte has an address associated with it, this address is normally a number. The computer’s memory is a sequential collection of storage cells, each cell commonly known as bytes. We know the computer use a memory to store the data items which are stored in memory cells. Pointers are the variables which hold memory address of another variable or in other words Pointers are the variables that store the location of a data item, such as variable or array element. Pointers are one of the powerful tools in C language.

The second operator is indirection Operator *, and it is the complement of &. You should read the & operator as 'the address of' which means &var will be read as 'the address of var'. This operator has the same precedence and right-to-left associativity as the other unary operators. For example, if var is an integer variable, then &var is its address. The & is a unary operator that returns the memory address of its operand. (dot) operator and the -> (arrow) operator are used to reference individual members of classes, structures, and unions. A variable can be any data type including an object, structure or again pointer itself. C++ provides two pointer operators, which are (a) Address of Operator & and (b) Indirection Operator *.Ī pointer is a variable that contains the address of another variable or you can say that a variable that contains the address of another variable is said to 'point to' the other variable.
