In C++, objects can be input and output using operator overloading. For object input, the stream-extraction 

operator >> is overloaded for the appropriate istream classes and for object output, the stream-extraction 

operator << is overloaded for the appropriate ostream classes. In each case, only the object’s data members 

are input or output in a form meaningful for objects of that particular abstract data type. When object data 

members are output, the object’s type information is lost in a way. However, if the program that is going to 

read this data knows what object type it corresponds to, then the data is simply read into objects of that 

type.
