Dynamic memory allocation of class objects in C++

Dynamic memory allocation is a process that allows us to do exactly what we’re looking to do above, to allocate memory while our program is running, as opposed to telling the computer exactly how much we’ll need (and for what) ahead of time.

Example-: int *ptr; ptr=(int *)malloc(8); This allocates 8 contiguous bytes of memory space and the address of first byte is stored in the pointer variable ptr . This space can hold 4 integers. Unlike memory allocated for variables and arrays, dynamically allocated memory has no name associated with it.

You can allocate memory at run time within the heap for the variable of a given type using a special operator in C++ which returns the address of the space allocated . This operator is called new operator.
