Multithreading in c++???
As far as i know, c++ does not provide any language level
support for multithreading. If it is to be implemented
using c++, then it cannot be done without the support of
the underlying operating system which makes things a little
more complicated, unlike java, where a language level
support is provided for the same.
And, difference between multithreading and single-
threading: Multithreading is one form of multitasking where
a single big task is divided into independent, simultaneous
operations which can run together so that subtasks
independent of eachother can be implemented at once to
improve efficiency.

Question In a class, there is a reference or pointer of an object of another class embedded, and the memory is either allocated or assigned to the new object created for this class. In the constructor, parameters are passed to initialize the data members and the embedded object reference to get inialized. What measures or design change should be advised for proper destruction and avioding memory leaks, getting pointers dangling for the embedded object memory allocation? Please suggest.

Answer # 1 use copy constructors 0 Shanthila There is something to be taken care in destructor, in copy constructor, suppose the memory is assigned to the embedded member object pointer with the parameter passed value, but if some other objects of different class also are pointing to this memory, then if some one deletes the object then this class member pointer object will become dangling, or if the object is not deleted properly then there will be memory leak. Please suggest the design change required to handle or avoid this situation
