You cannot get the source code to an EXE because the source code is not saved with the EXE. When it is compiled, the variable and function names get changed so they cannot be reverted. If you want to figure out how it works, then learn the EXE format.

I haven't actually downloaded the files, but if they're simple programs, you could actually write the code yourself.. If they're more advanced (or you're just too lazy to do that) then that won't work (see LB's explanation)...

You can decompile a C++ program but writing from scratch is usually simpler
