一个数据导入的有趣问题

Visual Studio Code for C++ development on MacOS

I've tried lot's of c++ IDEs on MacOS X, but none of them is as powerful as VS Studio on Windows. It's always hard for me to choose an IDE before I want to write some code, as it's called the Selection phobia. Generally we have the following choose:

• Vim/Emacs (I'm familiar with VIM but it's still not an easy way, for me)
• CodeBlocks (not good maintained on MacOS)
• CodeLite (it's a good choose!)
• XCode (I just don't like it, Heavy and ugly, can't get used to it)
• QT Creator (it's useful especially when developing Qt projects)
• Eclipse CDT
• NetBeans
• CLion (maybe the best c++ IDE on MaxOS, unfortunately does not have a free version)
• Textmate

Recently I tried Visual Studio Code, it's really a good choose for those who want to write some c++ code in a lightweight IDE.
