The first comment is really the basis of the issue.
sprintf will let you store off the results into a variable for later use, while
printf will simply wrap the results and send them to
STDOUT (or the CGI page).
For example:
# Using printf
printf( "%100s\n", 'This will just print to STDOUT; will not return ot
+herwise.' );
# Using sprintf
my $var = sprintf( "%100s\n", 'This will be stored off to $var, where
+I will use it later' );
print_var( $var );
sub print_var {
my ( $data ) = @_;
print $data;
}
This specific example will really, effectively, do the same thing. Although it can sometimes be nice to use the formatted result of
sprintf in other areas of a given application.
Hope this helps, and good luck!
