It takes in the new item to be passed in as a parameter. This allows us to push new items to the last index of a vector. Here's an example: Webb14 maj 2003 · Unlike Python, where __init__ is just a specially-named method, In C++ constructors cannot be handled like ordinary member functions. In particular, we can't take their address: &World::World is an error. The library provides a different interface for specifying constructors. Given:
