The term "operator new" is used incase when u are
overloading the global "new" operator.We can overload ne
operator just as any other operators i.e +,-,*,=etc.

The term "new operator" is used in case of dynamic
allocation of memory.When a variable is allocated memory
dynamically the new operator is used.
Eg:
int *p=new int;
//here p is pointer to integer.So in order to allocate
memory for it we have used the new operator.
