Operations encountered under Linux (continuous update ...) ）

1. The job lets write an input and output redirect, pipe connection. That's not what I'm talking about here. But I wanted to write a program to demonstrate these features: But I found out that my virtual machine was not loaded with the GNU g++ Command, and then it was amazing to find that the Linux command line could be directly networked to download the installation:

Command: sudo apt-get install build-essential

And then I installed Codeblocks, found that Linux under the Codeblocks has the ability to automatically detect the compilation environment, directly detect the existence of the GNU!!
