What problem does the copy-constructor solve in C++?

Pointer arithmetic errors
Object slicing issues
Incorrect initialization during object copying
Memory leaks during dynamic allocation

The correct answer is: Incorrect initialization during object copying

The copy-constructor in C++ solves the issue of incorrect initialization during object copying. It ensures that the copied object is properly initialized with the same values as the original object. This is particularly helpful when dealing with complex objects that contain pointers or dynamic memory allocations. Option A, pointer arithmetic errors, is not related to the purpose of the copy-constructor. Option B, object slicing issues, refers to a problem in polymorphism where a derived class object loses its specialized attributes when copied into a base class object. Option D, memory leaks during dynamic allocation, can be addressed by using smart pointers in C++, but is not directly solved by the copy-constructor.
