Strangely it appears that i do not receive all emails from the list.


isdigit() checks if a chatacter is a digit.

conversion constructor sounds like a regular value constructor. Example:


class A
{
 int x;

 public:
 a(int r):x(r) {}
};


// ...


A a=7; // a temporary object in place of 7 is created
       // using the constructor


A conversion operator defines the behaviour of an object when used
together with the mentioned type.


Example:


class A
{
 string x;

 public:
 a(string r):x(r) {}
 operator string() { return x; }
};

// ...

A a("Nice!");

string s=a; // A::operator string() is called
