    Problem With undefined reference to `WinMain@16' in Code::Blocks Version 10.5 2011

    okay so im trying to test out my code with the virtual keywords and i dont seem to know what is happening here with this error

    Code:
    #include <iostream>
    using namespace std;
    
    
    int main()
    {
        
        {
               cout << "hello my name is dominic test";
        }
        int myass;
    
        myass = 1 + 1 =;
    
        int dooshbag 2 + 2 =;
        
        virtual bool myass *dooshbag;
    
        system ("pause");
        return 0;
    }
    ERROR
    c:\program files\codeblocks\mingw\bin\..\lib\gcc\mingw32\4.4. 1\..\..\..\libmingw32.a(main.o):main.c|| undefined reference to `WinMain@16'|


    iv looked at forums on this and i have made my file a c++ file tbh i think its a linker issue with dlls from windows 7 but thats just a guess at it

    or a code error that im not seeing which would be very typical :P

    i know my code is not cleaner *cba*

    i also tried doing the hashinclude <iostream.h>

    maybe im using the virtual keyword wrong and the meaning of it is wrong? doubt it tho

    I would expect several compile errors from that, e.g.,
    Code:
    MODE:strict errors C++ C++0x_extensions
    
    "ComeauTest.c", line 13: error: expected an expression
          myass = 1 + 1 =;
                         ^
    
    "ComeauTest.c", line 13: error: expression must be a modifiable lvalue
          myass = 1 + 1 =;
                  ^
    
    "ComeauTest.c", line 15: error: expected a ";" (perhaps on the previous statement)
          int dooshbag 2 + 2 =;
                       ^
    
    "ComeauTest.c", line 17: error: invalid specifier outside a class declaration
          virtual bool myass *dooshbag;
          ^
    
    "ComeauTest.c", line 17: error: "myass" has already been declared in the current
              scope
          virtual bool myass *dooshbag;
                       ^
    
    "ComeauTest.c", line 17: error: expected a ";" (perhaps on the previous statement)
          virtual bool myass *dooshbag;
                             ^
    
    "ComeauTest.c", line 11: warning: variable "myass" was set but never used
          int myass;
              ^
    
    "ComeauTest.c", line 15: warning: variable "dooshbag" was declared but never
              referenced
          int dooshbag 2 + 2 =;
              ^
    
    "ComeauTest.c", line 17: warning: variable "myass" was declared but never referenced
          virtual bool myass *dooshbag;
                       ^

    Compiler issue.com ant it lol god sake nothing works the first time can you help me then where would be my next step from this point onwards and how do you know what the next plan of action is anyways so i can learn from it

    ofc i could read your errors but i wouldnt get the meaning of it all

    You should:
    • Write in proper sentences.
    • Learn C++ from say, a beginner's book.
    • Decide on the requirements of the program that you set out to write.

    I am absolutely certain that you have no clue as to the valid uses of the virtual keyword.

    all i need is my problem fixed? so i can learn from your wording on how to fix it i learn by doing and telling not from reading books infact i hate reading from most books because its mostly very general and bias towards coders and not really friendly at all and doesn't explain the meaning of everything in pure english so one person who isnt a computer geek can go in and understand so he can become a coder geek im sorry if this ........es you off its not intenshonall

    It is impossible to fix your problem when you have not told us what your program is supposed to do, considering that it is unclear from the code what your program is supposed to do.

    Thank you for saying that

    im just looking at virtual keywords and seeing how they work atm!

    but then i got that fail of an error and felt like Foisting my computer box into my ceiling

    So your idea was to just try and code something with the virtual keyword and see if it works, and if it didn't, you post the code on a forum hoping someone will come up with an example that works? Sorry, but you're headed for disaster.

    Where did you come across the virtual keyword? What do you think it is for?

    i didnt think they would be this big problem tbh i dont understand this problem provoking that c++ brings its like unbearable but anyways

    the meaning of virtual is to give dynamic access and i read somewhere that it may even create virtual tables tht store arrays but i was looking at the dynamic access meaning first to see if it was true or not

    then i got that error

    You read that somewhere? And you are the same person who wrote:

    I am going to point you to this tutorial on polymorphism, though I am not sure if there is a point because your hapzard acquisition of fundamental C++ knowledge means that you might not even understand what is a class.

    a class is a like a storage point for specific variables that can be called to run multitude of c++ statements then say a int mostly but can be used for other things id imagine but its more major then say a interger which is less minor then a char which is a small version of interger which is used to speed up applications,etc if used correctly.

    i ant stupid i just learn differently

    also im looking to do OpenGl programming and SDL And! OpenAL i just want to get the hang of wxwidgets first but i need to fully grasp the meaning of some c++ keywords and symbols before i move forward in my tutorials of wxwidgets

    Virtual members
    A member of a class that can be redefined in its derived classes is known as a virtual member. In order to declare a member of a class as virtual, we must precede its declaration with the keyword virtual:


    so this is how i interpretate this

    so basically a variable of a class and what virtual does is allows it to be dynamic class so its a access point which is what i said lol but you were telling me that it gives dynamic access but only to classes is what your trying to tell me? or?

    It sounds like you are confusing classes with objects, and then "specific variables that can be called to run multitude of c++ statements then say a int mostly" does not make sense.

    I am not saying that you are stupid, but "just learn differently"? Everyone with any decent proficiency in programming learned it by doing. But they did not learn it only by doing: they had books, notes and tutorials that they read, and perhaps teachers that they listened and consulted. Pretending that you are different and hence must learn by writing test programs out of thin air to discover the syntax and semantics of a programming language is just setting yourself up for failure.

    Oh, and please do not try to use this forum as some anonymous bunch of teachers for you to consult.

    That would be wise.

    No, in this context the virtual keyword declares the member function as virtual, i.e., you can override it in a child class. You have to understand this in the context of inheritance and polymorphism.

    Obviously you do not listen and try to push the blame upon those who try to help you. Well, it's your loss. Good luck with your failing.
    I will also recommend that you learn how to split sentences instead of writing one long unreadable block of text. There is a reason we have sentences, you know.
