# C 程序：创建，初始化和访问指针变量 > 原文： [https://beginnersbook.com/2019/02/c-program-to-create-initialize-and-access-a-pointer-variable/](https://beginnersbook.com/2019/02/c-program-to-create-initialize-and-access-a-pointer-variable/) 在本教程中，我们将编写一个 C 程序来创建，初始化和访问指针变量。要学习指针的基础知识，请参阅我的教程： [C 指针](https://beginnersbook.com/2014/01/c-pointers/)。 ## 示例：用于创建，访问和初始化指针的程序 在下面的程序中，我们声明了一个字符变量`ch`和字符指针`pCh`，之后我们用 `char ch`的地址值初始化了指针变量`pCh`。 该示例还说明了如何使用指针变量`pCh`访问`ch`的值和地址。 ```c /* Created by Chaitanya for Beginnersbook.com * C program to create, initialize and access a pointer */ #include <stdio.h> int main() { //char variable char ch; //char pointer char *pCh; /* Initializing pointer variable with the * address of variable ch */ pCh = &ch; //Assigning value to the variable ch ch = 'A'; //access value and address of ch using variable ch printf("Value of ch: %c\n",ch); printf("Address of ch: %p\n",&ch); //access value and address of ch using pointer variable pCh printf("Value of ch: %c\n",*pCh); printf("Address of ch: %p",pCh); return 0; } ``` **输出：**  #### 相关 C 示例 1.
