# Copy Constructor in C++  |  Learn CPlusPlus

A [copy constructor in C++](https://learncplusplus.org/learn-how-to-use-types-of-destructors-in-c/) is a special constructor that creates a new object as a copy of an existing object. It takes a reference to an object of the same class as an argument. The copy constructor is used to ensure that the copied object is a distinct instance, preserving the original object's data integrity.
