[英]Print struct member
#include <iostream>
using namespace std;
struct Person {
string first_name;
string last_name;
};
int main() {
Person a;
a.first_name = "foo";
a.last_name = "bar";
cout << a.first_name << " " << a.last_name;
return 0;
}
Gives error: 给出错误:
binary '<<' : no operator found which takes a right-hand operand of
type 'std::string' (or there is no acceptable conversion)
Why is it happening? 为什么会这样呢?
As others have mentioned in the comments, you need to include string
: 正如其他人在评论中提到的那样,您需要包含
string
:
#include <iostream>
#include <string>
using namespace std;
struct Person {
string first_name;
string last_name;
};
int main() {
Person a;
a.first_name = "foo";
a.last_name = "bar";
cout << a.first_name << " " << a.last_name;
return 0;
}
