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?

I know

Answer 1

for what value of x both statements will be executed?

There is no such value: either the value evaluates to true (something != 0), or it evaluates to false) (0). No other possible values exist.

I know we can execute if-else together like this: if(1){ goto ELSE; } else{ ELSE: }

That works but it isn’t depending of the value of the if condition at all.
