Use vim gcc/g++ to compile CPP (c + +) files under Mac and run

First confirm GCC and g++ versions, whether they are consistent

Command: gcc-v;g++-V

And then vim

Write C + + files, such as: #include <iostream> ...

Remember when you last save, Exit+:sav+cppname.cpp.

The ". cpp" suffix guarantees that the compiler recognizes the C + + file, so that when you compile, if you are GCC, you know that you automatically know which class libraries (C + +) to call, and note that there is no suffix or error written ". C", the class library is not found at compile time

Then: Wq

Command: LS, there is a XXX.cpp C + + source file under the current directory

g++ Xxxx.exe-o XXX.cpp

Then LS, you will see the current directory XXXX.exe

Compiled files, directly using:./xxxx.exe run on it.

Finally, CTRL + C, exit
