强制类型转换的优先级是多少？

maxxfire

上表从上到下，优先级由高到低。。
另外还有两个NOTE：
Note 1:
    Parentheses are also used to group expressions to force a different order of evaluation; such parenthetical expressions can be nested and are evaluated from inner to outer
Note 2:
    Postfix increment/decrement have high precedence, but the actual increment or decrement of the operand is delayed (to be accomplished sometime before the statement completes execution). So in the statement  y = x * z++; the current value of z is used to evaluate the expression (i.e., z++ evaluates to z) and z only incremented after all else is done.

强制类型转换可以看作一元操作符, 优先级与这些一元操作符相当:!(逻辑非) .(位取反) -(负号) ++(加1) --(减1) &(变量地址)

(Type*)p->a;

void * pData；//pData是存在的一块儿已知内存

((TYpe*)pData)->a;
这样就可以对任意指针 扣上任意结构体的形式，还能直接赋值

呵呵，看来又成水了
