Question

I have a c++ class, let’s say it’s called c, and I want to use the implicit copy constructor in one of the methods, like this:

c c::do_something() {   c copy = this; //I want implicit copy constructor here!   copy.something_else();    //........//   return copy; } 

However, gcc returns this error:

error: invalid conversion from ‘c* const’ to ‘long unsigned int’

(I have another constructor from long unsigned int present)

… as if the copy constructor didn’t exist. What am I doing wrong?

Answer 1

this is a pointer to an object so it should be

c copy = *this;
