"字符串"类型无法解析Eclipse C++

Question

我想这样做:

#include <string>

class Medicine{

    string name;


};

但它根本不起作用.我尝试右键单击项目 - >索引 - >搜索未解决的包含,它说:未解决包含在项目中(0匹配).它也不能用于std :: string.我该怎么办？

您应该完全符合string它所属的命名空间(std):

#include <string>

class Medicine {
    std::string name;
//  ^^^^^
};

或使用using声明:

#include <string>

using std::string; // <== This will allow you to use "string" as an
                   //     unqualified name (resolving to "std::string")

class Medicine {
    string name;
//  ^^^^^^
//  No need to fully qualify the name thanks to the using declaration
};
