so a will increment 2 instances inside if ailment. But given that the situation is not going to turn into real, It will likely not enter Within the if-loop and third increment will not likely happen. So the ultimate price of a would grow to be twelve In such a case.
A not(X or Y) selector could well be wonderful to avoid inflating specificity, but I assume we will really have to persist with combining the opposites, like in this response.
Now suppose, in the same higher than case in point If we use shorter-circuit && operator. then immediately after analyzing ++a==ten to false, It won't go to check the 2nd argument. And As a result the ultimate price of a would-be eleven.
Here's an example of exactly what the bitwise or does: if a=0101 and b=0011, then a
$a=somecommand # Non permanent variable to retail outlet exit status of the final command (given that we won't create to "$?")
And it has an increased purchase of precedence than OR, so parenthesis are needed to demonstrate what element you want regarded as by the OR assertion. See msdn.microsoft.com/en-us/library/ms190276.aspx
