    #include <stdio.h>
    #include <conio.h>


    int main ( void )
    {
    textcolor(BLUE);

    cprintf( "This is a test\n" );

    int main(void)
    is correct c and equivalent to
    int main()
    in c++

    i.e. in c++ there is no difference between
    int main() and int main(void)
    Free the weed!! Class B to class C is not good enough!!

    Your linker errors are probably down to cprintf() or textcolor(). Read the faq for text colouring details on a windows box. dev-c uses mingw as its compiler. This is a windows compiler.

    hmm, i never knew that, but i guess it would make sense.....rather than use either or would it be better to use

    Code:
    int main(int argc, char* argv[])
    {
    }
    ?

    //also, sometimes when i let VC 6.0 create my cpp file for me and it uses that with stdafx header sometimes it'll compile error that it cant open that header file, but then i make another one the same way and it works....

    Its best to keep things simple....

    in c you want

    int main(void)
    or if you are using command line args...
    int main( int argc,char* argv[])
    or its functional equivalent...
    int main( int argc,char**argv)

    in c++

    int main()
    or if using commandline args same as for c.

    You've been here how long, and you don't read the FAQ on main() usage?
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
