Std::getline not needed? HELP

[Barry117]

my code seems to compile and run with no errors or bugs but i’m wondering if there is an underlying reason why Ben said to use it in these instances?

Hi @Barry117, so this is possible because of the Argument-Dependent Lookup a.k.a. ADL
or Koeing Lookup. Basically it works like this, getline() should not work, but with the ADL the function look inside of it owns arguments getline(std::cin, response) and find the std:: there, when this happens, inside the std:: exists the function getline(). So now getline() can use the std:: like this std::getline(). Got it? The link below can explain better then me.

see link Argument-Dependent Lookup

That’s perfect your message was enough for me to understand : ) so basically in this instance as i’m using getline(std::cin, response); the std:: is picked up after the getline function. so the use of std:: in this context is purely cosmetic and makes the code easier to understand for someone who may have stumbled across the line.

I’m glad that I could help you understand.
See ya next time! Byee!
