They can also be passed as pointers, if you want to use them. Thought I believe it's considered better to use references over pointers when possible.
void foo(MyClass* obj)
// class passed by reference
MyClass myclass; // create an instance of the class
foo(&myclass); // pass it to another function
MyClass* myclass = new MyClass;//create a pointer to the class and allocate an object at its location
foo(myclass);//call the function
delete myclass;//deallocate the object
Can u plz explain the internals of passing object reference to a function as parameter....that at the compiler level what will happen if i pass object as value and what will happen if i pass objet as reference to a function as parameter
Many of your questions can be answered, as Ancient Dragon suggests, by reading a book. Another appraoch that I find very useful (especially for C++ hidden behavior) is to write a small sample program to test things out. If you write a small class with a copy constructor, assignment operator, constructor, destructor and other methods you might want to evaluate each with a std::cerr print statement in them you will see where each is invoked.
