const char*和 char const*以及 char*const

char * const cp; ( * 读成 pointer to )  
cp is a const pointer to char  
 
const char * p;  
p is a pointer to const char;  
 
char const * p;  
同上因为 C++里面没有 const*的运算符，所以 const 只能属于前面的类型。  

 

const int n=5;    //same as below 
int const m=10; 

const int *p;    //same as below  const (int) * p 
int const *q;    // (int) const *p 

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
