where size(a variable) specifies the number of elements in an array.Allocate block of memory: new operator is also used to allocate a block(an array) of memory of type data-type.HereвЂ™s an example for the initialization of both data types :Д¬ust* var1 = new cust // Works fine, doesn't require constructorД¬ust* var1 = new cust() // Works fine, doesn't require constructorД¬ust* var = new cust(25) // Notice error if you comment this line For custom data types a constructor is required (with the data-type as input) for initializing the value. Initialize memory: We can also initialize the memory for built-in data types using new operator.Data-type could be any built-in data type including array or any user defined data types including structure and class. Here, pointer-variable is the pointer of type data-type.Syntax to use new operator: To allocate memory of any data type, the syntax is:.If sufficient memory is available, new operator initializes the memory and returns the address of the newly allocated and initialized memory to the pointer variable.

The new operator denotes a request for memory allocation on the Free Store. This article is all about new and delete operators. C++ supports these functions and also has two operators new and delete that perform the task of allocating and freeing the memory in a better and easier way. How is memory allocated/deallocated in C++?Д¬ uses malloc() and calloc() function to allocate memory dynamically at run time and uses free() function to free dynamically allocated memory.

If programmer doesnвЂ™t deallocate memory, it causes memory leak (memory is not deallocated until program terminates). For dynamically allocated memory like вЂњint *p = new intвЂќ, it is programmers responsibility to deallocate memory when no longer needed. How is it different from memory allocated to normal variables?ДЇor normal variables like вЂњint aвЂќ, вЂњchar strвЂќ, etc, memory is automatically allocated and deallocated. Examples of such cases are Linked List, Tree, etc. There are many cases where this flexibility helps. We are free to allocate and deallocate memory whenever we need and whenever we donвЂ™t need anymore.

The most important use is flexibility provided to programmers.

One use of dynamically allocated memory is to allocate memory of variable size which is not possible with compiler allocated memory except variable length arrays.

Dynamically allocated memory is allocated on Heap and non-static and local variables get memory allocated on Stack (Refer Memory Layout C Programs for details).
