Q: What does follow code mean?

g++ -c file1.cpp file2.cpp file3.cpp

That line refers to compilation process using command line on a Unix based system.
Let's break it down

g++ is the target comiler by which you are going to compile three files which are parts of the same project (in the same directory).

-c is a compiler flag (command line option) which compiles all three source files into three object files as file1.o, file2.o, and file3.o.

Then you would link them by
g++ file1.o file2.o file3.o

and run it by
./a.out
