Getting string from class object

Question

I made a bitset based string class and it has it's own getstring function. How can I make it so that whenever I call the object, It will call that function then return the result. I want it like the actual string class where you can just do std::cout << strobj; and it will just print the string. Currently whenever I call my bitstring object it requires a method. How do I make it like string's?

Thanks in advance

You should overload `operator<<` – Hatted Rooster Nov 28 '18 at 16:02 — Hatted Rooster, Nov 28 '18 at 16:02
overloading operator const char*() will also work – grapes Nov 28 '18 at 16:10 — grapes, Nov 28 '18 at 16:10
How does one "call" an object? – JaMiT Nov 29 '18 at 04:28 — JaMiT, Nov 29 '18 at 04:28

Its hard to answer this without seeing your code, but it sounds like you want to implement something like this

class Foo(){
  public:
  std::string GetString(){return myString;}
  std::string SetString(std::string str){myString = str;}

  friend std::ostream& operator<<(std::ostream& os, const Foo& foo)
  {
    return os << "My String Is:" << GetString() << "\n";
  }
  private:
  std::string myString;
};

made edits to the post, renamed bar to myString – HappyKeyboard Nov 28 '18 at 16:20
That makes it `foo.GetString()` then, that's the purpose of passing foo as an argument, no? Also I doubt `class Foo() {` will compile? – TrebledJ Nov 28 '18 at 16:25
