如何捕获此结构向量？ C ++

Question

So I've made a class, one of it's function returns a struct vector, like so:

vector<highscore::players> highscore::returnL(){
    load();
    return list;
}

So list is basically,

struct players {
            string name;
            int score;
    };
    vectors<players> list;

In my source cpp, I tried to capture this vector, so I made another struct and struct vector. Source.cpp:

struct players1 {
        string name;
        int score;
};
vector<players1> highscorelist;

Then I tried to

highscore high; //class' name is highscore
highscorelist = high.returnL();

But I get the error message:

No operator "=" matches these operands
" operand types are std::vector<players1, std::allocator<players1>> = std::vector<highscore::players, std::allocator<highscore::players>> "

Is it not possible to do it this way? I honestly don't know what to search for so this might have been answered before, apologize if that's the case.

Answer 1

You could use reinterpret_cast , but that's not a good solution. Why don't you use highscore::player ?

std::vector<highscore::player> highscoreList;
highscoreList = high.returnL(); // ok

highscore::player and player1 are different types, even though they have the same variables and probably even the same memory layout. You cannot just interchange types like that. Also, if you change one of those types, you have to change the other, which is just a maintenance nightmare if it were possible.

If you can, you could also use auto :

auto highscoreList = high.returnL();
