C++ 允许用户声明结构对象的最佳方式？

Question

#include <iostream>
#include <string>

using namespace std;

struct player
{
  string name;
  int money = 100;
  int wins = 0;
};

int main()
{
  string user;
  cin >> user;
  player user;
  user.name = user;
}

What is the proper syntax for this in C++? I'm trying to declare the object name as the one given by the user. How would you do this? Would a class be easier to do this? Any tips/advice is much appreciated!

Answer 1

variables names are meaningless at runtime in compiled langages like c++. If you want to refer to a player using his or her provided username at runtime you need a datastructure that will remember the name as as string, like a hashtable or a map (I would recommend a map, those are easier to use) http://www.cplusplus.com/reference/map/map/

Answer 2

best is classes because of security as by default , classes are private in nature but struct are public in nature

#include <iostream>
#include <string>

using namespace std;

class player
{
  public:
  string name;
  int money;
  int wins;

  public(string name){
  this->name = name;
  this->money = 100;
  this->wins = 0;
}

};

int main()
{
string user;
cin >> user;
player *user = new player(user);

}
