    Constructor question

    Do the member initializers of a constructor run in the order that they are listed?

    For example, can j reliably initialize to n + 1 in this example?
    Code:
    struct s {
    	int i;
    	int j;
    	s(int n)
    		: i(n), j(i + 1)
    	{}
    };

    No, the construction oddly enough is actually done in the order that the member variables are declared.
    What you posted would work, but this would fail:
    Code:
    struct s {
    	int j;
    	int i;
    	s(int n)
    		: i(n), j(i + 1)
    	{}
    };
