Hi,

Does replacing printf by print make any difference in the program?
Especially at places where there is no format string passed or just $_
is passed?

Regards,
Pradeep

It probably doesn't have a noticeable difference unless you compare the
running of it many, MANY times. But using printf() needlessly is silly,
and in some cases, dangerous. If you have a % sign in your string, printf
will expect an argument to go with it.

Just for the record, another formal difference is that printf does
not add $\, which might not be a problem anyway.

I second the remark of japhy, be specific, use print when you mean
print.
