1、指针数组：array of pointers，即用于存储指针的数组，也就是数组元素都是指针；数组指针：a pointer to an array，即指向数组的指针。
int* a[4]     指针数组    
                  表示：数组a中的元素都为int型指针    
                  元素表示：*a[i]   *(a[i])是一样的，因为[]优先级高于*
int (*a)[4]  数组指针    
                  表示：指向数组a的指针
                  元素表示：(*a)[i]  

2、下面通过实例来说明数组指针与指针数组的区别：  
#include <stdio.h> int main() {     int c[4]={1,2,3,4};     int *a[4];   // 指针数组     int (*b)[4]; // 数组指针     int i=0;     int j=0;     b=&c;     // 将数组c中元素赋给数组a     for(i=0;i<4;i++)     {         a[i]=&c[i];     }     // 输出看下结果                                                                                                       printf("%d\n",*a[1]);// 输出2     printf("%d\n",(*b)[1]);// 输出2     printf("%d\n",(*b)[2]);// 输出3     for(i=0;i<4;i++)     {         printf("value at %p = %d\n",(b[0]+i),*(b[0]+i));     }     return 0; }
