    default constructor

    Code:
    class base{
       private:
            int x;
       public:
           base(){
             x=4;   
         }
    };
    is it correct to do this? set x=4 in a default constructor? want'ed to set the initial value of a variable in class that gets created by a default constructor.

    Your question is, is it correct to properly initialize an object? Well... yes?

    The only thing that isn't quite right is that you should initialize members like this:

    Code:
    base::base()
      : x( 4 )
    {
    }
    Instead of what you have there (i.e., use the initializer list)
    Code:
    //try
    //{
    	if (a) do { f( b); } while(1);
    	else   do { f(!b); } while(1);
    //}
