Private and protected member variables

  
#include <iostream>
using namespace std;

class MyClass {
  int a;           // private by default
protected:         // still private relative to MyClass
  int b;
public:
  int c; 

  MyClass(int n, int m) { 
     a = n; 
     b = m; 
  }
  int geta() { 
     return a; 
  }
  int getb() { 
     return b; 
  }
};

int main()
{
  MyClass object(10, 20);

  object.c = 30; // OK, c is public

  cout << object.geta() << ' ';
  cout << object.getb() << ' ' << object.c << '\n';

  return 0;
}
