I'm also on Hugh's side here: Never ever do uninitialized somethings.  If 
you want "implicitely initialized", that's fine with me, but then initialize 
to zero (for values and pointers).  Programs simply behave better if you 
make sure everything is deterministic.  If zero isn't the right value to 
initialize, you'll quickly figure out, and explicitely initialize; but if 
it's uninitialized, changes are high that it is 95% zero (especially on the 
first run in the clean system where you enter the definition on the command 
line to try it), and your program crashes unexpectedly in the 5% where it's 
"some leftover" instead.
