从楼上的表中可看出
（）里的东西最先结合
[ ]的优先级高于*的优先级
若类型为char,char *p[10]可以理解为有一个数组，数组的10个元素都指向char类型的数据
若类型为char,char (*p)[10]先结合*p,表示指向十个一维数组的指针
例如 char a[3][10]; char (*p)[10]=a; 可用来访问数组的每个元素。
p[2][1]表示第三行第一列的元素。

//C++ Operators
// Operators specify an evaluation to be performed on one of the following:
// One operand (unary operator)
// Two operands (binary operator)
// Three operands (ternary operator)
// The C++ language includes all C operators and adds several new operators.
// Table 1.1 lists the operators available in Microsoft C++.
// Operators follow a strict precedence which defines the evaluation order of
//expressions containing these operators. Operators associate with either the
//expression on their left or the expression on their right; this is called
//“associativity.” Operators in the same group have equal precedence and are
//evaluated left to right in an expression unless explicitly forced by a pair of
//parentheses, ( ).
// Table 1.1 shows the precedence and associativity of C++ operators
// (from highest to lowest precedence).
//
//Table 1.1 C++ Operator Precedence and Associativity
// The highest precedence level is at the top of the table.

int *p[10]
p首先是个数组，因为它先和[10]结合
其次，这个数组里面存的内容是int*,也就是数组有10个元素，每个元素都是一个指针，
int (*P)[10]
p先和*结合，意味着p是一个指针，他指向int [10]，即p是一个指向一个数组的指针

比如int *p[10]，也可以这么写 int* p[10]，p是一个数组，数组元素p[i]的类型是int*，就是指向int的指针。
比如a[3][10]，它包括a[0][10],a[1][10],a[2][10],a[0],a[1],a[2]可以表示成a[i]==*(a+i)，所以(*P)[10]，p可以等于a+i，p是指向大小为10的数组，p的增一减一是以一行为单位的（比如3行10列）。

看看预算符: * []的优先级和结合性。
*p[10]
*(p[10]);

*p[]和p[][]差不多意思吧

你可以把(*P)[10]看成P[0][10]
而*p[10]只能是*(p[10])

完全不一样...
