所以我有这个名为User的类。在里面我创建了一个名为flight的结构,我想在这个类中创建一个函数来返回一个带有航班值的结构。那可能吗?像下面这样的东西。我知道它不起作用但有办法吗?
Class User
{
string name, surname...;
struct flights
{
int miles;
double cost;
}
struct add_miles(reads from another class);
}
struct User::add_miles()
{
return flights;
}
答案 0 :(得分:1)
我不确定我清楚地理解你的要求,但看看我的尝试:
#include<iostream>
class User
{
//string name, surname...;
public:
struct flights
{
int miles;
double cost;
}myflights;
struct flights add_miles()
{
return myflights;
}
};
int main()
{
User me;
me.myflights.miles=100;
std::cout<<me.add_miles().miles;
}

您必须让add_miles
返回flights
结构,而不仅仅是struct
。
示例代码:
#include <iostream>
using namespace std;
class User
{
private:
string name,
surname;
public:
struct flights {
int miles;
double cost;
};
flights add_miles() {
return flights();
}
};
int main(int argc, char **argv) {
User u;
User::flights f = u.add_miles();
cout << f.miles << endl;
return 0;
}
