[求助]C++变量的声明与定义题

TC++PL 5.9

1. (*1) Write declarations for the following: a pointer to a character, an array of 10 integers, a reference to an array of 10 integers, a pointer to an array of character strings, a pointer to a pointer to a character, a constant integer, a pointer to a constant integer, and a constant pointer to an integer. Initialize each one.

3. (*1) Use type def to define the types unsigned char , const unsigned char , pointer to integer, pointer to pointer to char , pointer to arrays of char , array of 7 pointers to int , pointer to an array of 7 pointers to int , and array of 8 arrays of 7 pointers to int .

其中，红色部分不会做！
哪位帮帮忙！谢谢！
1.
a reference to an array of 10 integers（一个到包含10个整数的数组的引用）
a pointer to an array of character strings（一个到字符串的数组的指针）

3.
pointer to arrays of char
pointer to an array of 7 pointers to int
array of 8 arrays of 7 pointers to int

I'am trying...

a reference to an array of 10 integers（一个到包含10个整数的数组的引用）
a pointer to an array of character strings（一个到字符串的数组的指针）

1. int (&arr)[10];
   
2. string (*parr)[];

复制代码

pointer to arrays of char
pointer to an array of 7 pointers to int
array of 8 arrays of 7 pointers to int

1. typedef char (*parr)[];
   
2. typedef int *(*parr)[7];
   
3. typedef int *arr[8][7];

复制代码

man cdecl

十分感谢kernelxu！

1.
//a pointer to a character
char* pc;

//an array of 10 integers
int array[10];

//a reference to an array of 10 integers
int (&r)[10] = array;

//a pointer to an array of character strings
char* (*p)[]; // 如何赋值呢？
//char* tmp[] = {
//        "a pointer", "to", "an array",
//        "of", "character strings"
//};
//p = tmp;


//a pointer to a pointer to a character
char** ppc;

//a constant integer
const int i = 0;

//a pointer to a constant integer
const int* pi = &i;

//a constant pointer to an integer
int *const pci = array;


3.
//unsigned char
typedef unsigned char UCHAR;

//const unsigned char
typedef const unsigned char CUCHAR;

//pointer to integer
typedef int* PI;

//pointer to pointer to char
typedef char** PPC;

//pointer to arrays of char
typedef char (*PCARR)[];

//array of 7 pointers to int
typedef int* PI7[7];

//pointer to an array of 7 pointers to int
typedef int* (*PPI7)[7];

//array of 8 arrays of 7 pointers to int
typedef int* PI87[8][7];
