I thought this was a kind of interesting experiment (results included in comments in the file):
Dumb question: In order to run this outside of an IDE, exactly which file(s) would be needed? Just the .exe? or is the incremental linker file also necessary?Code:/* Testing how unnecessary #includes influence the size of the compiled file Compiled in VC++ 2008, here are the file sizes for the executable: 1) completely empty program with no #include: 27KB for .exe; 294KB for linker 2) #include <iostream>: 27KB; 302KB for linker file 3) #include <iostream> and #include <string>: 27KB; 302KB for linker 4) using namespace std; : 27KB; 314KB for linker 5) with both #includes as well as minimal code (no using): 33KB for .exe; 319KB for linker Conclusion here: #include has no influence on the size of the .exe but only on the linker file--and even there the influence is pretty small Only the USE of the libraries increases size of executable.
