Create a deep copy of an array C++

Question

I am try to solve some problems in my program and it would appear that there is either a problem with my copy constructor or with my destructor. I am getting a memory exception.

Answer 1

You can't just memcpy random objects, you need to actually copy them with their copy operators.

string most likely holds a pointer to heap-allocated storage. If you copy it bitwise, calling the destructor on the original string invalidates the "copied" string's data.

Use something like std::copy to do this properly.

#include 
...
std::copy(a.readArray, a.readArray+arraysize, readArray);
