    .exe size

    I've just gotten into C++ and am now able to creat basic consol programs.
    However i've come up with the problem that all the programs i make are always very large when complied into .exe (i got a 32 line program that is 1.2 mb)
    I've got this suspicion that it has somthing to do with the with the header files. (correct me if im wrong please)
    I use Dev C++ and the only header file i include is iostream.h

    How can I bring down these huge file sizes in the .exe?

    thx for your time

    That would be my best guess as well. Bloated libraries are a problem (though not as much as they used to be) with the implementation's design. You can't fix it, but you can complain to the vendor. That's always fun.
    My best code is written with the delete key.

    At least in VC++, try compiling in release mode, use smaller .exe options, optimize your code and the compiler settings, and align the file to smaller boundaries (compiler option).

    what version of Dev-C++? I suggest you get the newest version... I'm asking because the newer versions would give you a nasty compilation error for using iostream.h, because it's old and the new standard calls for iostream...

    Yes i have the lates version of Dev-C++

    After playing with the compiling optamising options I belive that that doesn't help or if it does it doesn't do very much.

    how can you include iostream.h with the newest version of Dev-C++?

    unless you defeated the warning, which would be almost entirely useless...

    Add -s in the Linker options in Dev-C++.

    You can find it in Project -> Project Options -> Parameters

    Make sure your not outputting debugging information or using static linking.

    A recent thread on this very subject is here
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Via removing the debug info i managed to shrink my 32 line program from 1.2 mb to 400kb.
    Still absurde but bearably absurde.
    Thanks alot for your help and input guys.

    Try using the command "strip yourexe.exe". It will take out all the debugging information and probably bring the exe down half it's original size.

    Another thing you can do is try to remove any header files that you do not need.
