If I have an array which its size is based on the user input, from some material, I need to use malloc function to allocate memory for that array what is known dynamic array. Don't forget to free it.hat's fine, however, I like to try things out even I know the program will crash.I have written some test program on my Mac using C language like this:int width = 0;//get user input, and assign the input value to width, for example, 3char * array_var[width];and width is an int, its value will be assigned by the user input. The point is, this program work as expected, for example, in command line, I input 3, then array_var length is 3, its size is 3 * sizeof(char *).

i've got certain functions now declared as static and their being used as pointers. So, moving on I then added a variable which so happened to be used in both static and non static functions. Here's some testbed code, the variable in question is 'window':

I have a char*[] array:

im trying to receive a string from user, then divide it into groups of strings with 3 elements only. meaning if input is:
12345 it should give 123 and 45
123456 it should give 123 and 456
1234567 it should give 123 and 456 and 7
anyway what happens based on my code is that it works fine with first two (when it has groups of 3 elements and 2 element, and also when it has groups of all 3 elements) but for the last case (when makes groups of 3 elements and 1 group of 1 element) it shouws as "123 456 7 D"!! meaning it adds one extra character to the last element out of no where!

I am trying to learn how to include common elements on every page. At first I made the mistake of calling it ssi but I do not think that is correct in php5. I downloaded phpb3 to look at and they are not doing it that way. they do it like this.

Problem is I can not find any articles that explain it. I even looked at the php manual and did not find it. Could someone explain this or point me in the right direction.
For Perl I need to understand a few things. It's unlikely that anyone will be able to give me direct answers but if they could point outI'm trying to hack down an existing script http://eoylpac.org/source/eoy.pl. What I need to be able to do (in a nut shell):1. Open a database2. Read the values for each uniq id and execute a subroutine for each of those values. (The subroutine already exists in the above file 'do_pdf').

View 3 Replies View RelatedI'm writing a PHP program. I've encountered a problem; in the following code I try to pass $_POST['delete'] which is an array as the value of a hidden input to some form, but it doesn't do so.there's something wrong with converting PHP array into HTML array. I'm sure that $_POST['delete'] is not null and is a real array.
echo '<input type="hidden" name="delete[]" value="'.$_POST['delete'].'" />';
Is there some way to access HTML elements via javascript through some internal ID?

I'm trying to make a combo box which should have elements dynamically taken from a database. I've an Exam Table,and it has columns Sno,Ename,Month,year. i need the combobox to list to the elements that are present in Ename.
i read some things in the web and tried that out in the netbeans. it said to rightclick the combobox and set bind ->elements and bind->selecteditem. But i'm not sure how to set the binding expressions inorder to get the required list in the combobox.

For example say we have:

I am running Ubuntu 10.04LTS (64bit) and the drives are formatted as EXT3. I have a Raid5 that had 4 x 1TB drives. It is mounted as my /home. I added a 5th Drive and used the Disk Utility to Expand the array. In the Disk Utility it shows as 4.0TB RAID5 Array, however when I open a console and type df -h it still only shows at 2.8TB (Which is the size of the 3TB array I had previously.) What do I have to do to have the 4TB array show up properly? I'm obviously missing something, but I'm not sure what it is.
