Hello,
I'd like to know whether g++ can detect a member variable which is not
initialized (on purpose) by the constructor.
Easier with a simple example (the class is supposed to be a fixed point
variable):
class A
{
private:
int my_value;
A (int init) { my_value = init; }
public:
A () {}
A (const A& init) { my_value = init.my_value; }
A& operator = (int scalar) { my_value = scalar << 8; }
...
};
int main (void)
{
int p, q;
A x, y;
p = q;
y = x;
}
g++ complains about q beeing used but not initialized, is there a way for it
to complain about x too ?
I tried the options -O -Wall -Wextra.
(yes I could put 0 in the constructor, but code size is critical in the
embedded environment I use, and I'm curious too :-)
I also tried "A () const {}" but it is refused.
I know from comp.lang.c++ that this is not a c++standard request to do so,
but there are always some interesting stuff in gcc that I don't know :-)
Thanks for any information,
david
