Hi dears, please look this...
@
if ( false==false==false )
qDebug()<<"Ding Ding !"; //UNREACHABLE CODE
@i think that it should be ok and print my message because of
FALSE is FALSE and FALSE will be FALSE!!!
compiler work with it's result which it returned. but why?
i know we need the result for if but... let's speak about it... -
Hi,
Off course this compiles (will give Wparentheses warning). The result will be not printing the output! Very simpel, the == operator does a compare of the first two elements (false==false) this will return true. Then do the compare of true==false -> result false, so your code does:
if (false)
{
}
So this does not work and will not print the output -
That's great! So if FFF is false, test FTF, you'll be surprised!
How does a brain works to find such things!
Very amusing.
