Compiling source files

C++ compiler goes through each source code file in the program and does 2 things:

1. makes sure the files follow C++ rules.
2. translates c++ code into machine language intstructions which are stored in object file (something.o).

linking object files and libraries

combines all the object files to produce the output file (executable file).

1. reads all the object files to make sure they are valid
2. resolves all cross-file dependencies.
3. linkes libraries

building

full process of converting source code to executable file. executable produced as a result is called a build
