提问by kaycee
i can't get rid of these errors... i have semicolons everywhere i checked... the code is simple: the error takes me to the definition "string name" in article.h...
我无法摆脱这些错误......我检查的每个地方都有分号......代码很简单：错误将我带到article.h中的定义“字符串名称”......
main.cpp
主程序
#include <iostream>
#include <fstream>
#include <vector>
#include <string>
using namespace std;
#include "article.h"
int main()
{
string si;
char article[128];
vector<Article> articles;
ifstream file;
file.open("input.txt",ifstream::in);
while(!file.eof())
{
file.getline(article,128);
articles.push_back(Article(article));
}
file.close();
while(1);
return(1);
}
article.h:
文章.h：
#ifndef Article_H
#define Article_H
class Article
{
public:
int year;
string name;
Article(char *i_name);
};
#endif

You should add:
你应该添加：
#include <string>
to your "article.h" header file and declare namelike this:
到您的“article.h”头文件并像这样声明名称：
std::string name;
回答by Patrice Bernassola
It seems the stringtype is not defined in the artivle.h file. Try to include iostreamand add using namespace std(or write std::stringinstead of using namespace)
似乎该string类型未在 artivle.h 文件中定义。尝试包含iostream和添加using namespace std（或写入std::string而不是使用命名空间）
回答by Péter T?r?k
You should use the std:: namespace prefix in the header, like
您应该在标头中使用 std:: 命名空间前缀，例如
std::string name;
