char ** p1;                                   //    pointer to pointer to char
const char **p2;                           //    pointer to pointer to const char
char * const * p3;                         //    pointer to const pointer to char
const char * const * p4;                //    pointer to const pointer to const char
char ** const p5;                          //    const pointer to pointer to char
const char ** const p6;                 //    const pointer to pointer to const char
char * const * const p7;                //    const pointer to const pointer to char
const char * const * const p8;       //    const pointer to const pointer to const char

注：p1是指向char类型的指针的指针；
        p2是指向const char类型的指针的指针；
        p3是指向char类型的const指针；
        p4是指向const char类型的const指针；
        p5是指向char类型的指针的const指针；
        p6是指向const char类型的指针的const指针；
        p7是指向char类型const指针的const指针；
        p8是指向const char类型的const指针的const指针。

typedef char * a;       // a is a pointer to a char

typedef a b();            // b is a function that returns a pointer to a char

typedef b *c;            // c is a pointer to a function that returns a pointer to a char

typedef c d();           // d is a function returning a pointer to a function that returns a pointer to a char

typedef d *e;           // e is a pointer to a function returning a pointer to a function that a pointer to a char

e var[10];               // var is an array of 10 pointers to functions returning pointers to  functions returning pointers to chars.
