    Devcpp: parse error before ';' token

    I recently got Devcpp 5, for my xp. I have version 4 running on my 95, and this program compiles fine there.
    Allso, where can I get non-antique headers, so it stops telling me I'm using an antique one.
    Code:
    #include <iostream.h>
    
    int main()
    {
      cin >> int q; //Here!!!
    }
    ERRORS:
    Code:

    > where can I get non-antique headers,
    It should already have them

    Try just
    #include <iostream>

    > cin >> int q; //Here!!!
    Try
    int q;
    cin >> q;
    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.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.

    > cin >> int q; //Here!!!

    You have to declare q first:
    int q;
    cin >> q;

    And the new header is called <iostream>. So:
    Code:
    #include <iostream>
    using namespace std;
    
    int main()
    {
      int q;
      cin >> q;
    }
    Or here's how without including the whole namespace:
    Code:
    #include <iostream>
    
    int main()
    {
      int q;
      std::cin >> q;
    }

    I don't see a need to create a new thread for this one so, I'l use this one. I decided to learn oop a few days ago, and for my first project I'm trying to make a duplicate of one of my structured programs. It compiles fine, and it does absolutely nothing. I added a loop - but.. any help?
    Code:
    #include <iostream>
    #include <stdlib.h>
    #include <time.h>
    using namespace std;
    
    class a
    {
          int q;
       public:
          a();
    };
    
    class m
    {
       protected:
          float pq[10], pau[10], pqq[10], pa[10], pd[10], pp[10], ps[10], pm[10]
                , pu[10], pbc[10], puc[10], pu1[10];
          int q, x, xx, xxx, t, w, a1, cccc, c2, cccr, r1, r2, ccc;
       public:
          m(int);
    };

    int main()
    {
       a cc1(); //it does nothing, not eaven displaying the text in it's constructor
       do{}while(1);
    }
    The original program "stra" is at my website. I'd add coments explaining everything, but my problem is in oop itself.
    Note: The game isn't operational if it did work, I just don't wan't to continue while it dosn't work to begin with.

    Arrow This is the modified source

    LMAO
    Ok, I got it. I guess any sugestions are welcome, but - I've sucesfully made the programm look the same as the structured version, except it's oop. Well, here it is:
    Code:
    #include <iostream>
    #include <stdlib.h>
    #include <time.h>
    using namespace std;
    
    class m
    {

                 , q, xxx, t, w, cccc, cccr, r1, r2, r3, ccc; //r1, r2 etc. = random
          int x, c2, xx, a1, g;

    };
    
    m::m (int o)
    {
       q = o; //holds how many players there are
       t = 0;
       ccc = 1;
       for (x=0;x<q;x++)//this sets the variables to the standard starting point

    I decided to take out the class 'a' and put it in the function 'main'. I don't think it's going to my website any time soon, because I need my dad to type the password for ftp

    You seriously need better names for all your variables and classes.
    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.

    Use a program that saves the ftp password, like smartftp or ws_ftp.

    Ya, pa stands for player atack, pbc stands for player buy cost etc. I guess I could take out the p in everything but it seperates the variables with the player info from everything else. The class m stands for main...

    And the reader of your code is supposed to know this how? Telepathy?

    >I guess I could take out the p in everything
    No, that would actually be a step backward. Your variables should be immediately obvious even if it means the names have to be longer than four letters.
    My best code is written with the delete key.

    LOL - stop working on it for a day, then see how much sense you can still make of it.
    Stop working on it for a week, and it will be hopeless.

    Half the variables in your class have no business being there - like all those loop and question/answer variables.

    And all those x[10] are screaming for an array of the class, not an array within the class.

    Instead of
    myclass foo;

    It would be
    myclass foo[10];

    I didn't look at the structured version for like 3 months, I used to be zornthrohacker(I quit posted when I stoped programming - now I'm back!)

    >Half the variables in your class have no business being there - like all those loop and question/answer variables.
    I'll get to that eventually...

    >And all those x[10] are screaming for an array of the class, not an array within the class. ...

    Why use a comment at just the declaration when your code can do it everywhere? If I gave you code and didn't tell you what it did, what would your reaction be if all of my variables looked like these:

    double pq[10], pau[10], pqq[10], pa[10], pd[10], pp[10], ps[10], pm[10], pu[10], pbc[10], puc[10], pu1, i, sd, q, xxx, t, w, cccc, cccr, r1, r2, r3, ccc;
    int x, c2, xx, a1

    I would bet my next paycheck that you would not be happy, and would probably become violent. My reaction has been similar in the past.

    >What do you meen
    An array of objects, not an object of arrays.

    The old version at my website (the one that dosn't work) explains what everythings doing. I'll go back through and add them to the oop version... EDIT: Done!

    Btw, as I modify the program, I'm editing the newer post with the working version(above with an arow).
