=false just way too time consuming? Why not rely on some boolean assignment operators to do the trick? To make something true, use
|=1. To make something false, use
How and why does this work? Let's take a look at each one seperately. In the true example, we have
|=1. What this basically means is take the value on the left of operator and perform a boolean OR (the pipe | ) on it with the number 1. When ORing, if both values are 0 then the result is 0. If either are 1 then the result is 1. By ORing our variable with 1, we guarantee that the result will always be true.
myvar=20; myvar+=20; // myvar = 40.
Okay, on to our second example:
&=0. This time we perform a boolean AND (the ampersand &) with the number 0. When ANDing, both values have to be 1 in order for the result to be 1. Otherwise, the result is 0. Therefore, we AND it with 0 to ensure that the result will always be false.
Just like that, you've saved 2 to 3 bytes per assignment! (cue parade...)
Ha ha ha! Nice!
why not just say =1and =0 ???
tim: but what's the fun in that? :)
