C++ Class and Preventing Object Copy Jan 10, 2015 4 min read #c++ #coding In some cases, an instance of a C++ class should not be copied at all. There are three ways to prevent such an object copy: keeping the copy constructor and assignment operator private, using a special non-copyable mixin, or deleting those special member functions.

Explain the copy and private constructor with an …

The first constructor is an Instance Constructor of a class with three input parameters and second is a copy constructor with input parameter of a class object. When we assign some input values to class properties using instance constructor then with the use of copy constructor we can create copy of data stored in an object to another new object as shown below code snippet.
