i changed it from C/C++: Edit configurations (UI) and it says i have new version but whenever i check i have c++98 even though i changed it to c++20. (i can figure out what version i am using from this code : https://coderslegacy.com/c/check-cpp-compiler-version/. oh ye and reason why i wanted to change this in the first place was because i couldn't use __gcd function. PLS HELP.
