C语言_题_逆序字符串

#include<string.h>
#include<assert.h>void func(char *left,char *right)
{assert(left);   //避免传空指针assert(right);while (left < right){char tmp = *right;*right = *left;*left = tmp;left++;right--;}
}int main()
{char arr[101] = { 0 };gets(arr);int len = strlen(arr);int left = 0;int right = len-1;//逆序整个字符串func(arr,arr+len-1);//逆序每个单词char* start = arr;char* end = start;while (*start){while (*end != ' ' && *end != '\0'){end++;}func(start, end - 1);if(*end != '\0')end++;start = end;}//outputprintf("%s\n", arr);return 0;
}
