Hi,

(AFAIK) whenever any object is dynamically created it is stored in heap. For eg:

class A
{
A();
};

void fun(A * a)
{
a = new A();
}

Here the object a will be allocated in heap.

In C, you can make use of malloc(), calloc(), realloc() functions to
dynamically allocate memory so that they gets stored on heap.
In C++ you can use new to dynamically allocate memory so that they gets stored on heap.

In C++ you can use new to dynamically allocate memory so that they gets stored on heap.

Be more firm about this:

In C++ you must use new to dynamically allocate memory so that they get stored on heap.


malloc() and free() do not call constructors or destructors so you can't use them in C++.
