You can't do this. Since aDavid is now static, it must be initialized outside of any class member or function (i.e., file scope) just like I showed.

Three of these in baseball means the batter is out. Should I be careful?

oops i've said the opposite!!, in cricket, when you say "strike" it doesn't only mean to bowler or a batsmen, if he strikes with a bat , then its a nice "Strike"!, if the bowler takes *YET ANOTHER* wicket, then we say, the bowler *strikes again*, but in general, for a batsman, we say.. "a nice stroke".. so what i mean here..
The problem has been batting here for a while... nobody could take its wicket.. and the ultimate, awesome bolwer named david crow came in.. and took the wicket (the batsman is out) in just two balls... am i clear now?
[ in simple terms -> stikes again : shines again ] Cool | :cool:

david , just a question in baseball!, when you say its a "strike", does it refer to the chuker,bowler,(how do you say??).. or the batter?..

"its a strike for the bowler"
or
"its a strike for the batsman"

?? Confused | :confused:

In baseball, the term "strike" refers to the pitch that was thrown (by the pitcher). If a batter swings and misses, the pitch is automatically a strike. If the batter does not swing, the pitch might still be a strike depending on where the ball fell within the strike zone (the conceptual rectangular area over home plate which defines the boundaries through which a pitch must pass in order to count as a strike when the batter does not swing). Does that help?

ohh.. you strike again (in my terms!!), that makes sense to me. baseball too sounds interesting,.. but everytime i try to watch it i get puzzled,. now i get an idea about it Cool | :cool:

.. but i still can't guess why the batter run all around the ground.. and one guy running here and another running there..anyway.. thanks for the explanation david!!

The batter's ultimate goal is to hit the ball in such a fashion that he can run around the bases and back to home plate, thus scoring a point for his team. That's a very simplistic explanation. A batter may also have a goal of sacrificing his own attempt to score so that a runner on one of the other three bases might advance or score a point. For example, if a runner is on third base, the batter might bunt the ball towards first base knowing that he will get out but hoping that his action will result in the runner on third scoring a point. This is called a Run Batted In (RBI).

The nine players out in the field (i.e., defense) have the task of catching or fielding a batted ball. If a batted ball is caught in the air, the batter is automatically out. If the batted ball hits the ground first, the batter becomes a runner and attempts to run to as many bases as he can without getting out. He is out if he is tagged by the ball, or if the ball beats him to the next base. It gets way more complicated than this, and if you are really interested in the rules, they can be found here. Rules for other leagues (e.g., college, high school, little league) may vary slightly, but overall they are the same.

Uh, no. Why would you think that? It's being defined and declared only once.

That's how static members are initialized because they don't belong to any particular instance of a class. Hence they must be initialized before any other. Note the class name prefix before the variable name.
