1. `int x = 2;`：这是一个变量声明语句，它声明了一个整数类型的变量 `x` 并将其初始化为 2。2. `2 * x`：这是一个表达式，其中 `x` 的值是 2，所以表达式的值是 2 * 2 = 4。3. `x += 2`：这是一个复合赋值操作符，相当于 `x = x + 2`，这里的 `x` 值为之前的 ...
And when it looked like China would have to settle for another draw, Omar outmuscles the defender to the ball in the final minute and fires it home to give the Mexicans a 2-1 victory, and the tournament title. China finish bottom with two draws and one loss....

其实这个是运算符优先级的问题，*= 其实就是先 * 再 = ，赋值运算符优先级很低，先进行它右边的运算 参考资料：http://baike.baidu.com/view/262524.htm
即Slot1 INTA#->Slot2 INT B#->Slot3 INTC#->Slot4 INTD#。这种交错叫做Swizzling,也就是上上图中的黄框部分。Swizzling交错之后的INTx,再经过Straight映射,即红框部分的直接映射方法变成PIRQx。 外部PCIe设备 PCIe的设备有一个PCI设备没有的问题,每个PCIe链路下只有一个EP(End Point)设备,这个设备的中断请求...
