Evaluation Order in a Condition statement

#1 March 18th, 2008, 08:35 PM

Hello.

Let A and B be 2 boolean expressions.
In the instruction if(A && B){/*..*/}, does the standard certify that A
will be evaluated first ?

Thanks a lot.

Even more: if A yields false, B is not evaluated at all.

This is absolutely right! Lazy evaluation!
