c++ versus masm

[clamicun]

Last week I "translated" one of my Masm programs into c++.
It is not better or worse but the exe file is much larger.
Probably not very well written.

Think I stay with Masm.

For those interested, here is the source compiled with dev-cpp.
My machine: Windows10 64b

strip off debug-info and size is 918 KB
and without static crt size is 902 KB

[clamicun]

TimoVJL,
This is the first c++ program I ever wrote.
I haven't the slightest idea what you mean.

[TimoVJL]

Check this in Dev-C++:
Project -> Project Options ... -> Compiler -> Linker  -> Strip executable (-s) Yes

Ctrl+H opens Project Options.

and then size is something like 920 KB.

[clamicun]

ok. Thanks

What is the size of your masm version?

[clamicun]

50% smaller

What is more surprising is that the background.bmp alone accounts for 778KB, this is a real miracle

50% smaller

the background.bmp alone accounts for 778KB

Assembly rocks!

Thank you all,
the masm version doesn't use the bmp on the mainwindow.
That's the secret

[daydreamer]

isnt the right word you "discompiled" your masm code?
(like disassembler,but opposite C++ compiler)
modern C++ compiler has an advantage of not including functions/PROC that are never called and assembly has its advantages of make code small,could it be possible to have conditional assembly do the same thing make assembler code even smaller?

[jj2007]

Absolutely, daydreamer! Why don't you test it and post an example?

...not including functions/PROC that are never called...

If you make assembly programing in a modular way, assemblers don't include functions never called. 

[TimoVJL]

uasm supports COMDAT with it's own way.

a smart linker don't include unused code.
