When you construct an object using new, you have no control over where it gets created in the heap. What if you want the object to be placed at a specific address? You can do this by using placement syntax in C++. The following example explains how.
class sample{private: int i;public: sample( int ii) { i=ii; } ~sample() { } void *operator new(size_t sz, void *q) { return(sample*) q; }};void main(){ void *address; address = (void*) 0xF00F; sample *p= new (address) sample(10);p->~sample();}
