const int initializer for Vector within a class

[hebrerillo]

Hi There!!

I am trying to initialize a Vector within a class like this

#include <iostream>
#include <string>
#include <cstring>
#include <vector>
using namespace std;
class Cars {
public:
  const static int MY_CONSTANT = 4;
  
private:
  vector<string> cars (MY_CONSTANT);
};

But the compiler gives me this error related with the constant static variable MY_CONSTANT:

‘MY_CONSTANT’ is not a type

What am I doing wrong?

Thank you in advance!!

An in-class member initialiser must be a brace-or-equal-initializer

private:
  // vector<string> cars (MY_CONSTANT);
  std::vector<std::string> cars { MY_CONSTANT };
};

Avoid using namespace std; at namespace scope, particularly in a header file.
Should the vector cars be a static member of Cars?
As far as possible, avoid using two names which differ only in case at namespace or class scope.
