Editing a file containing C++ code: The file containing C++ code is called your “source code” or just code. The code is a sequence of statements in the C++ language, each having a specific action/meaning associated with it.

Compiling: This is a very complex process that we will grossly simplify here as two steps. First, the compiler (we will use a compiler called GNU, but there are many different compilers marketed) will check your program’s syntax (have you used the language correctly?), issuing compile errors accordingly. If all is correct, it will produce an “executable file” that contains the binary translation of your source code which will run on the computer and do the tasks you programmed.

Testing: Just because you have written and successfully compiled a C++ program doesn’t mean that you have a correctly running solution to your problem. You must test the program to see that it indeed correctly solves the problem you set out to solve
