Re: [Dev-C++] ":" Operator

[Graham D. <g.d...@nt...>]

It's not an operator, it starts the member intialiser list. This can be 
used to intialise both the base class and member variables. e.g.

class bar
{
public:
    bar(int i) : barmember(i) {}
private:
    int barmember;
};

class foo : public bar
{
public:
    foo(int i) : bar(i), foomember(10) {}
private:
    int foomember;
};
