With that I fully agree, except it's not always possible or
natural. The issue at hand usually turns up with
conditional initialization, like:
void foo ()
{
int t;
if (something)
t = 1;
else if (something_else)
t = 2;
if (t == 1)
bar ();
}
That's a simple example of course, but more complicated
conditionals aren't so easy to grok and spot the bug.
In the case above, I'd much prefer if the compiler tells me
I missed initializing 't' than initializing it to 0 "just
in case".
Thanks,
