C++ 翻转字符串里面的单词 代码

以下是 C 语言翻转字符串里面的单词的代码：

#include <stdio.h>
#include <string.h>

void reverse(char *start, char *end) {
    char temp;
    while (start < end) {
        temp = *start;
        *start++ = *end;
        *end-- = temp;
    }
}

void reverseWords(char *s) {
    char *wordStart = NULL;
    char *temp = s;

    while (*temp) {
        if (wordStart == NULL && *temp != ' ') {
            wordStart = temp;
        }
        if (wordStart && (*(temp + 1) == ' ' || *(temp + 1) == '\')) {
            reverse(wordStart, temp);
            wordStart = NULL;
        }
        temp++;
    }

    reverse(s, temp - 1);
}

int main() {
    char str[] = "hello world";
    printf("Original string: %s\n", str);
    reverseWords(str);
    printf("Reversed string: %s\n", str);
    return ;
}

以上代码可以翻转字符串里面的单词，例如将 "hello world" 翻转为 "world hello"。
