— Isn't the keyword constexpr clear enough to you?

— It's clear as a term, but not it's usages and restrictions

— Like, with C++20 we will be able to do constexpr funcs virtual and have try blocks inside

— There are similar differences in 11/14

— 

There's few restrictions. An important one is that the code can't invoke undefined behaviour, which is pretty sensible

— Hey guys , is there a way to buggy a directory list crawler in c++?

— What?

— I coded a a function to find all files , directories , and sub directories with its files , but at the moment to change it to D: second hard drive it skips some folders

— This is what I am talking about

— What IDE are you working on?

— Visual studio 2019

— Include windows headers, put a

system("pause");
at the start of main, and run it in the console, then go to vs, press ctrl + alt + p and select your program, now press any key in the console and you got a debugger attached
