Why do we have to pass the previous class by reference?
Did not understand a concept of COPY CONSTRUCTOR
hello @priyamthakuria27
A copy constructor is called when an object is passed by value. Copy constructor itself is a function. So if we pass an argument by value in a copy constructor, a call to copy constructor would be made to call copy constructor which becomes a non-terminating chain of calls. Therefore compiler doesn’t allow parameters to be passed by value.
