G'day bartender1382,

"What I don't know how to do ... turn off a specific bit whether it is set or not."

Update: This wasn't a good solution (see reply below). The following would have been better:

#!/usr/bin/env perl use strict; use warnings; my $var1 = 0b00010100; my $var2 = 0b00000110; my $fmt = "%08b\n"; print "Initial:\n"; printf $fmt, $var1; printf $fmt, $var2; for my $bit (0, 1, 4) { print "Bit $bit off:\n"; $var1 &= ~(1 << $bit); printf $fmt, $var1; $var2 &= ~(1 << $bit); printf $fmt, $var2; }

I've stricken the original code; it's in the spoiler. The output is unchanged.


Initial: 00010100 00000110 Bit 0 off: 00010100 00000110 Bit 1 off: 00010100 00000100 Bit 4 off: 00000100 00000100

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
