This code works! Is it said we could not take address of register variable?
int main() {
register int a;
int *p;
a = 8;
p = &a;
cout << "a=" << *p <} ///:~

请教一这样一类game：
1. game 本身是infinately repeated；
2. player 是 short-sighted 的，譬如 maximize 一个 period 的 payoff ；
3. state of the stage game 是变化的，也就是说 state variable；
类似 Bequest Game，但是 Bequest Game player 是 maximize 两个 periods 的 payo
ff 的
有没有什么paper 用到我说的这个 framework，想参考一下，多谢！

7.1.1
3 A register specifier has the same semantics as an auto specifier
together with a hint to the implementation that the object so declared
will be heavily used. [Note: the hint can be ignored and in most
implementations it will be ignored if the address of the object is
taken. --end note]

Which book?
Thinking in C++ V3 one:
Register variables
...
There are restrictions to the use of register variables. You cannot take or
compute the address of a register variable. A
register variable can be declared only within a block (you cannot have
global or static register variables). You can, however, use a register
variable as a formal argument in a function (i.e., in the argument list).

"you can not take the address of a register variable" means if you do, then
it is no longer a register variable
my quote is from the c++ standard, if any other book is against it, the book
must be not precise or could be even wrong

or

because it is not wrong..."can not" itself is not a precise word, it doesn't
say if you do it, what will happen. for a book, it is ok to say that.

You do answer the question very well. Thanks! We have different opinion to
the words from TIC which is misleading readers.
