Setting up CPP In Mac

Well after seeing countless videos, let me summarize it for you !!!

There are two types of compiler variant available for MAC.

1. Provided by xcode-developer support called clang
2. Another one is provided by GCC/GNU , can be downloaded by command brew install gcc

To check which version you are using

1. Run g++ , if it shows clang then , you are using xcode variant
2. if it shows some a string like g++-13 in the compilation then you are using the GCC/GNU one

If you want to use both of them, you can easily choose between them :-

1. g++-14 <filename> : for GNU/GCC
2. g++ <filename> : for the clang

If you want to work with bits/stdc++.h , you must use GNU/GCC based compiler.

1. If you’re using vscode do check, at which compiler locations your g++ settings points.

I just add an alias in my .zshrc file

alias g++="g++-14"
alias gcc="gcc-14"

But if you do want to execute your code using clang++ then you can use following command ?

clang++ -std=c++17 mul_table.cpp

Why was all this necessary ?

• Because of the fact that clang doesn’t support #include<bits/stdc++.h>
• Which was annoying for me…
• Hope this helps !!
