conditions in WHILE loop
Hi,
in while loop like this
class A* a;
while (a && a->something1==something2) {body}
when a=NULL what is correct:
1) i get error because i cant get "a->something"
2) loop always check 1st condition and if it is true then check 2nd 3rd... so it will work propraly
thx

Option 2) is the correct one.
'a' will be checked first. If it's not 0, other conditions are checked.
So, it is good to use it.
