[RESOLVED] if(x ==y) && (a == b)

dcjones

Hi all,

I have been asked a question by a fellow coder concerning if statements.

The question was, what is the difference between the code below and which one is the correct way to write the code;

if(x == 'Y' && w == 'X') {
print "yes";
}

if(x == 'Y') && (w == 'X') {
print "yes";
}

The second one is incorrect because you've got an if() statement followed by a logical AND followed by a boolean expression.

Actually all are invalid because you aren't using $ to properly denote your variables.

They aren't 'invalid' in the sense that they cause parse errors; it's quite possible to define constants in place of variables. Still, I presumed the question referred to the difference in grouping of the expressions, thus I focused my reply on that issue.
