 */

class foo {      // define class named foo
  public:
    foo();       // constructor
    void bar();  // function
};

foo::foo()
{
  // Implement the constructor from outside the class
}

void foo::bar()
{
  // Implement bar from outside the class
}

void bar()
{
  // Implement different bar which is not within the same scope
