In this video we will learn about overloading operator new and operator delete in C++ programming language. Basically overloading new and delete operator gives developer more flexibility for heap allocation.
There are few points to note as follows :
1 There are two different types of overloading.
a. Local Overloading (class/struct)
b. Global Overloading
2. Syntax for Overloading operator new
void* operator new (size_t size);
3. Syntax for Overloading operator delete
void operator delete(void*);
4. Both new and delete operator are static members functions. So they don't have access to this pointer (we don't have to write static keyword it is automatically static).
5. Don't forget to overload for array version of both (new/delete).
6. We can have multiple overloaded new/delete operator functions.
