I have never seen this sort of thing and its hard to imagine C++ would include such a feature. Just for curiousity's sake, could you provide a link to where you found this example? And AncientDragon is right, you need to call strtok() multiple times.

Does the text overflow the width of the paragraph? Let me know if there is any CSS that would affect the <td> or the <p>.

Have you tried setting the width of <td> to an actual value? <p> tags should word wrap automatically if the width is specified.

In here:

<td width=""><p><?php echo nl2br($message); ?></p></td>

Apart from it you can initiate a char array and then get the input through simple scanf() function.

Scanf can look simple, but it actually does a lot of work under the hood which obviously will slow down your code. Also, it can cause lots of problems if you don't know exactly how it is matching input. It seems like a good idea at first but it is generally regarded as bad coding practice in most cases.

fgets to get the string, strtok to tokenize it. To do this multiple times, just put your code inside the body of a loop.

That's a sensitive thing to do

But the correct thing to do, as "\n" is a pointer, not a char. Comparison between a char and a pointer to a char cannot be expected to work properly (who knows what "properly" even means here?)

Learn database functions for whatever db server your client uses (MySQL, whatever). A tutorial on SQL statements and the php manual will help you with this.

EDIT: Sorry, Aia beat me to it.

Put this:

if (!$user_check) {
die('Invalid query: ' . mysql_error());
}

in between this:

$user_check = mysql_query("SELECT userdb_user_name FROM default_userdb WHERE userdb_user_name='$reciever'");

and this:

$user_check = mysql_num_rows($user_check);

and tell us what is displayed.

Can you explain that? I understand what Ancient Dragon did, but what about the "lock" concept?

mysql_fetch_array returns an array, just a the name implies, so this statement:

$new_Number_value = $query_results_Number++;

is trying to increment an array?
You want some thing like this:

$new_Number_value = $query_results_Number["Number"]++;

Do not use goto: in C applications. It is very bad coding practice (see spaghetti code). Instead, use control structures like conditional statements, loops, etc.

Then instead of setting the input variable to "18-2-21" (obviously not what csurfer intended), use fgets to get a line of user input. Also you could use sscanf() as long as you make sure to check its return value!

You can use a tm structure for the date of birth, convert it with mktime(), and subtract that from time(). Then convert your answer back into a tm struct.

Where exactly are you calling session_start()? And that error just means you have some sort of output (check for spaces, newlines before your <?php tags) before you have called session_start(). If you have to do this, consider output buffering.

A bubble sort but with the comparison flipped.

Good point. With both under your belt, not only will it strengthen your overall programming knowledge, the flexibility it would give you would be more impressive on a resume.

What is the problem with using || ? It is a completely valid part of the C language. There might be some obscure way of doing the same comparison without it, but it would be useless to even try it.

You're right, that's different from:

char sudoku[] = { '0', '0', '1', '0', '0', '0', '0', '0', '9',
                  '6', '0', '8', '7', '9', '4', '0', '2', '0',
                  '0', '0', '9', '1', '0', '5', '0', '0', '0',
                  '0', '0', '0', '6', '7', '0', '0', '0', '2',
                  '0', '8', '0', '0', '0', '0', '0', '6', '0',
                  '0', '9', '0', '4', '3', '0', '0', '5', '0',
                  '0', '0', '4', '0', '0', '0', '0', '1', '0',
                  '9', '3', '0', '0', '1', '0', '8', '4', '0',
                  '0', '0', '2', '0', '4', '3', '0', '0', '0' };

C will convert actual numbers into the ascii character at that index.
To get the char from a number:

char seven = 7 + '0';

Obviously that code is unecessary, but when working with variables it becomes useful.

Point taken, sorry.

If you have to use array notation, also consider using a static variable instead of a parameter:

void enter(int *p_arr)
{
  static int insert = 0;
  printf("\nplease enter the number:");
  scanf("%d", &insert);
  p_arr[i++]=insert;
}

There's a good reason why you're not supposed to feed the bears. If you give them something for free, they'll expect that all the time and won't figure out how to feed themselves. It would seem that people can be the same way...

You could use the WinAPI file functions (http://msdn2.microsoft.com/en-us/library/aa364232(VS.85).aspx) which allow you to set sharing permissions (as well as other flags and such for the sort of thing you described).

He didn't mean you should change it to 0, he meant thats what your code equated to. He meant you should either set or prompt for a product number. The first product in the display is still zero because you started your loops at 1, therefore skipping the 0th element of the array (the one that actually had a value). This is also why there are only 6 days in the week and 4 products.
