Each project in solution can be executable or library

visual studio new add new cpp file : [ctrl + shift + A]

source file → executable binaries / libraries

operators are just fuctions

every cpp file compiles individually into obj files → stich together with linkers into one exe

just compile this cpp file : [f7] Only Compilation happens, no Linking

Compilers : convert all the code into constant data & instructions

in C++ unlike java, there is no such thing as a file.

file is just a way to feed compiler with source code. Your responsible for telling kind of file type and how should compiler treat that

this does not produce .obj file
