从你给出的报错信息可知,代码里存在以下几个问题: 1. `vector` 未声明,需要包含 `<vector>` 头文件,并且使用 `std` 命名空间。 2. `vector` 声明时未指定元素类型,应当明确元素类型。 3. `stringstream` 未声明,需要包含 `<sstream>` 头文件,并且使用 `std` 命名空间。 下面是修改后的示例代码: ```cpp // main.h #include <vector> #include <sstream> #include <string> // 假设 reverseWords 函数定义如下 std::string reverseWords(std::string s) { // 声明一个存储字符串的向量 std::vector<std::string> words; // 使用 stringstream 分割字符串 std::stringstream ss(s); std::string word; // 按空格分割字符串并存储到向量中 while (ss >> word) { words.push_back(word); } std::string result; // 反向拼接单词 for (auto it = words.rbegin(); it != words.rend(); ++it) { if (!result.empty()) { result += " "; } result += *it; } return result; } ``` ```cpp // problem2.cpp #include "main.h" #include <iostream> int main() { std::string s = "hello world"; std::string reversed = reverseWords(s); std::cout << reversed << std::endl; return 0; } ``` 代码说明: 1. 在 `main.h` 中包含了 `<vector>`、`<sstream>` 和 `<string>` 头文件,以使用 `std::vector`、`std::stringstream` 和 `std::string`。 2. `reverseWords` 函数将输入的字符串按空格分割成单词,存储在 `std::vector<std::string>` 中,然后反向拼接这些单词并返回结果。 3. `problem2.cpp` 中包含了 `main.h` 头文件,并调用 `reverseWords` 函数进行测试。 [2025-11-12 14:49:29 | AI问答 | 489点数解答]
