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。
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。
/* 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:
