Initialization Allocating Memory In C++

Whenever we want a variable to dynamic memory allocated so we have to use new keyword for that time or if we want to new keyword through  allocated memory to destroy so we have to use delete keyword. Like that we can do memory initialization or deletion.

Syntax:

data type *variable name=NULL;

variable name=new data type;

*variable name=value;

Example:

int *a=NULL;

a=new int;

*a=20;

Program:

#include<iostream.h>

#include<conio.h>

void main()

{

int *a=NULL;

a=new int;

*a=20;

cout<<”example of initialization allocated memory”;

cout<<a;

delete a;

getch();

}

Output:
