condition precedences in 'if'

[mahmoodn]

Dear all,

First consider this:
bool flag = false;
while (condition) {
   ...
   if ( !flag && ANOTHER_CONDITION ) {
      ....
   }
}
If the "while" loop iterates for 10 times, the both flag and
ANOTHER_CONDITION are checked 10 times.

Now consider this:
bool flag = false;
while (condition) {
   ...
   if ( !flag && ANOTHER_CONDITION ) {
      ....
      flag = true;
   }
}
If the "while" loop iterates for 10 times and in the first iteration "flag =
true;" is executed, then how many times, ANOTHER_CONDITION is checked? 1 or
10?

How does GCC-4.1.3 act to condition precedences?
