A simple question about "print" function Can't Post
Hello !

Can someone explain me please why
print 3==4;
prints nothing ?

I would expect 3==4, which is false, to be converted to 0, so I expect "print" to print "0". Where am I wrong ?

Thanks !

As far as I know perl will not convert the result to zero or true or false. You have to tell it to. Here is one way of doing it.

Code
print 3 == 4 ? 'True' : 'False';

Hi,

Thanks for the reply !

So what I don't understand is what Perl does with 3==4 ?

Why print 3==3; prints 1, and print 3==4; prints nothing ?

Thanks in advance !
