what is raii and functors and how do i utilize these in order to become the greatest programmer in the world
im downloading the boost library now, i dont know why i think i will succeed in installing its complicated ass but apparently the secret is to learn a library at a time and to get clever with modern prgrmn tricks like raii and functors (sound like westside story bouncer names)
what are they, and should i just learn qt instead? its just that qt actually feels too easy and i dont understand why any of the coding does anything that it does do which is not the point of learning for the sake of it like i am

The majority of boost is headers only. If you know how to type
#include you can use it.
so whats raii and functor when they not bouncing mafiosos
@moschops its not that eeasy code blocks an boost hate me, i can add headers but not ones like asio which need libs :( i guess its java for it then

RAII is a poor name for when you deallocate resources in the destructor.
Why is this important? Because there's no garbage collector in C++ to free resources if something bad happens, like an exception being thrown.

Functors are objects used as functions, with the help of operator()():
