# C 程序：創建，初始化和訪問指針變量 > 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，我們將編寫一個 C 程序來創建，初始化和訪問指針變量。要學習指針的基礎知識，請參閱我的教程： [C 指針](https://beginnersbook.com/2014/01/c-pointers/)。 ## 示例：用于創建，訪問和初始化指針的程序 在下面的程序中，我們聲明了一個字符變量`ch`和字符指針`pCh`，之后我們用 `char ch`的地址值初始化了指針變量`pCh`。 該示例還說明了如何使用指針變量`pCh`訪問`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; } ``` **輸出：**  #### 相關 C 示例 1.
