How to stop my character from going outside the div?

around this issue I think all you need to do is check the bounds in your keydown handler:
$(document).keydown(function(e) {

var position = $('#charlie').position(),
    width = $('#charlie').width(),
    max = $('.container').width(),
    step = 20;

switch(e.keyCode) {

    case 39: // right
    if ( position.left + width + step < max ) {
        $('#charlie').css('left', position.left + step + 'px').removeClass('flip');

    case 37: // left
    if ( position.left - step > 0 ) {
        $('#charlie').css('left', position.left - step + 'px').addClass('flip');

Get regex to stop at a certain character, but include that character in match

Tag : php , By : Juan Pablo

it fixes the issue Right now, this regex matches something and stops at a slash ( / ), but I need it to stop at the slash and include the slash. Or in other words stop at whatever character is after the slash. But, I don't know what that charcter is. , You can do it in 2 ways :

Is there a way to stop a RegEx before a character value and start another one after that character?

wish of those help I'll first suggest two alternate approaches, then answer your question as it stands.
Perhaps beter without regular expressions
// Multiplication of unparenthesized integers
Pattern p = Pattern.compile("(\\d+)\\s*\\*\\s*(\\d+)");
Matcher m = p.matcher(s);
while (m.find()) {
  int a = Integer.parseInt(m.group(1));
  int b = Integer.parseInt(m.group(2));
  s = s.substring(0, m.start(1)) + (a*b) + s.substring(m.end(2));

Using scanf for character input, but the do-while loop wont stop at the null character

this one helps. There aren't any nul-terminated strings here, but only string arrays.
So, when pressing enter, a[i-1] is \n not \0 (scanf with %c as parameter doesn't nul-terminate the strings, and ENTER is just a non-nul character with code 10 AKA \n)
#include <stdio.h>
      char a[50];
      int i;

      printf("Give max 50 characters\n");


            scanf("%c", &a[i]);
      while((i<sizeof(a)) && (a[i-1]!='\n'));  // \n not \0
      int j;
      for(j=0; j<i; j++)  // stop at i
            printf("%c", a[j]);  // output is flushed when \n is printed

PHP Remove Everything After Character and Stop Before Character

Tag : php , By : Patastroph

this will help Should be able to use PHP's strstr in-built function in combination with str_replace to get the result you're after
$string = '/my-picture-gallery-1000x2000.jpg';
echo str_replace(strrchr($string, '-'), '', $string) . strstr($string, '.');
$string = '/my-picture-gallery-1000x2000.jpg';

$dimensions = strrchr($string, '-');
$extension = strrchr($string, '.');

$image = str_replace($dimensions, '', $string) . $extension;
