在我的笔记本电脑上检查 C++ 版本

Question

I am currently in a CS class where we use C++, and I run Linux on my laptop. So the problem is that I think I don't have the most up to date version of C++. I've read online for several commands to get the version and this is my result. Also my Linux version is 16.04, and I am compiling in my terminal

tom@TBT-XPS-13-9360:~/Documents/Subjects/CS/OOP$ g++ --version
g++ (Ubuntu 5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609

I don' know what part of this is my actual version of C++. If my version is not the most up to date, can someone please give me DETAILED instructions on how to do it. Still getting my Linux legs.

Answer 1

C++ version (Or usually called c++ standard) is different than compiler version.

g++ is your compiler, and your current version is g++ (Ubuntu 5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609

You can use different command to compile your program using different C++ version.

g++ -std=c++11 yourFile .....
g++ -std=c++14 yourFile .....

As mentioned in the comments, this version of compiler may not support c++17 features yet

Answer 2

在终端中使用此命令（仅适用于 linux）

cpp --version

Answer 3

要获得 C++ 版本，请使用

c++ --version
