因为一直听说不适合直推。
但出于好奇 直接接在iphone4上
音量开到3/4的位置
好像声音也挺响。
难道我买到了假货？

As suggested by some big cow I file the 8863 (american education oppurtunity
) form with 1040 and I have around 1000 usd credits (for one quarter I paid
the tuition around 10k myself...) and I was charged a 900 usd tax by irs
and from the tax table, with my current income, I should pay 800 so the tax
return is 1000+ 900 - 800 = 1100
so I was only charged 900 but I can get a 1100 ??? is this too good ??
I need your help to figure this out I am not joking

Here's a common scenario: source file first.cpp define a static data member
of a class and provided an initializer for it. Source file second.cpp #
includes first.h and attempts to examine the value of the static data member
. When you execute that statement, the program crashes.The reason is the
compiler doesn't guarantee that C::i is initialized before it is referenced
in the second.cpp. Here is example:
//----first.h
class C
{
public:
static const int i;
};
//----first.cpp
#include "first.h"
const int C::i=5;
//----second.cpp
#include "first.h"
int MIN=C::i; // may crash here
Questions:
1. Do we have this problem in C too or only in C++? I have never noticed
this problem in C.
2. This seems a pretty serous problem. How to avoid it? E.g., if we use
singleton, how to make sure that the instance is initialized before use it?

Since C does not have class, static variable in C has different meanings
than in C++. So static variable in C means either 1) internal linkage (file
scope) 2) local static variable retains the value between function calls.

Thanks.
I tried the following code.
File1.c
int x = 1;
File2.c
#include
extern int x;
int y = x + 1;
int main() {
printf("x: %d y: %d\n", x, y);
}
If compile with gcc, it gives an error "initializer element is not constant"
. But it compile with g++. I guess in C it's not allow to initialize a
global variable from another variable. So no dependency problem in C.

C requires static initialization to be constant, i.e. known at compile time.
When the C compiler compiles File2.c, it doesn't know what x is, thus can
not initialize y.
Different from C, C++ allows static to be lazy initialized the first time it
's used at runtime. So if you put the static in a function, it gets
initialized the first time the function is called. By doing this, it
guarantees the static is always initialized before use.
