    int main()
    {
    return 0;
    }

    might do it

    C++ is a high level language so its not possible.

    Smallest is 24.0KB with VC++

    void main(){} or int main(){}

    doesn't matter which.

    GOT IT!!!!

    I made a program in C++ that was 955 bytes long.

    All it does is cause a segmentation fault, but it compiles and executes!

    >Smallest is 24.0KB with VC++

    This'd do it on MSVC++ -

    Code:
    #define main mainCRTStartup
    
    int main()
    {
    	return 0;
    }
    With the linker options -

    /NODEFAULTLIB /SUBSYSTEM:CONSOLE /OPT:REF /OPT:ICF /MACHINE:IX86

    Comes in at exactly 1 KB. You may be able to get it lower than that by tinkering with the options a little more. It's not really a valid C++ program but I'd guess most compilers have the option of turning off the default runtime.

    Removing the /NODEFAULTLIB in MSVC and compiling with the standard main produces a 3.5KB exe.

    Yes, but you'd have problems unless you want to code some of the start up runtime yourself.
