由于 Fedora 22 yum 已被弃用，因此其他答案中给出的命令实际上会启动 'Dandified yum' 即dnf。所以在最近的发行版中安装 g++ 的新命令是
su -c "dnf install gcc-c++"
As of Nov 2015 this installs the 5.1.1 version.
Also note that in Fedora 23 when I gave the command g++ -v, Fedora automatically asked me if I want to install gcc-c++ package. I think thats nice.(After the install it also ran the command g++ -vfor me)

Just make a sample 'Hello World' Program and try to compile it using "g++ sam.cpp" in terminal, and it will ask you if you wish to download the g++ package. Press y to install.
只需制作一个示例“Hello World”程序并尝试在终端中使用“g++ sam.cpp”编译它，它会询问您是否要下载 g++ 包。按y安装。
