Question 93 Explanation:
→Copy Constructor is a type of constructor which is used to create a copy of an already existing object of a class type.
→Declaration of copy constructor syntax is different from c++ to java.
→In C++, It is usually of the form class-name (Class_name &vn),
→In Java, the syntax is Class_name(class_name vn).
→So w.r.to C++ , option (B) is correct and w.r.to Java option (c ) is correct.
→Declaration of copy constructor syntax is different from c++ to java.
→In C++, It is usually of the form class-name (Class_name &vn),
