Chapter 11.1, Problem 11STE

Given the following definitions:

  const int x = 17;

  class A

  {

  public:

  A( );

  A(int x);

  int f( ) const;

  int g(const A& x);

  private:

  int i;

  };

Each of the three const keywords is a promise to the compiler that the compiler will enforce. What is the promise in each case?
