This article mainly introduces the use cases of pointers in C language, which is very detailed and has certain reference value. Friends who are interested must finish reading it.

First, use the pointer to reverse the string void _ reversal (char* left, char* right) {while (left)

< right) { char tmp = *left; *left = *right; *right = tmp; left++; right--; }} 通过上述代码不难看出，left与right分别代表一个字符数组的首端和尾端，通过中间变量 tmp进行首尾交换，left++中的left是char*类型，同时也可以看成为一维数组left[ i++]，因此，移动的原理就是通过++移向下一个元素位置所在的地址right同理可得是移向上一个元素位置所在的地址。
