I don't seem to be able to get classes very well. For example, let's say I put....
Code:class Player { int strength; } Player user;
so now, how do I edit the value of user.strength. When I use
it gives error. Saying that there is a syntax error before the "." Sorry for noob question, but I'm newCode:user.strength = 10;

Class members are private by default. If you wish to manipulate data members from outside class member functions, declare them as public...ie...
Oh, and as a side note, you're missing a ; at the end of your class definition.Code:class Player { public: int strength; };
yeah......that wasn't the actual code though. I do it public and with the ; at the end but it doesn't work :-/
Here's a quick look:
gives error :-/Code:class Player { public: int health; int strength; int agility; void move(); void attackMonster(); void getTreasure(); }; Player user; user.strength = 10;
Is that an actual cut/paste of the code as it appears in the program? Or related pieces shown together for convenience? Just curious since the compiler is giving you a syntax error, very well may be a simple typo (or something left out) somewhere in the few lines before the instance of user.
Generally you should not have public data members in a class; rather, you should use a struct or, in most cases, just make them private. Then you can have your member functions do all of the modifying of data.

In the future, try actually posting the errors you say you're getting.
Compile. Run. Be amazed.Code:class Player { public: int health; int strength; int agility; // void move(); // void attackMonster(); // void getTreasure(); }; int main() { Player user; user.strength = 10; return 0; }
Quzah.
Hope is the first step on the road to disappointment.
