Simultaneous execution of both if and else blocks

Question

In C or C++

if ( x )
    statement1;
else
    statement2;

For what value of x will both statements be executed?

Without devious trickery, no, this is not possible. Consider what the expression means:

if (cond) {
  ifTrue;
} else {
  ifFalse;
}

This says to execute ifTrue if cond is true (a non-zero value/true), and to execute ifFalse if cond is false (zero/false). Since cond can't be simultaneously true and false, you can't execute both ifTrue and ifFalse without a special case, such as goto.
