Clearing a 2D array

Hi Guys,

I have a simple problem with, what seems to me, should be a simple solution but it's just not working.

I have a 2D array declared as

Code:

*array[20]

This array is then dynmaically filled with 4 or 5 strings I then want to clear this array once I have finished with it.

I have tried runnig it through a loop such as

Code:

for (i=0;i<totalnumberofstrings;i++)
{
array[i] = '\0'
}

I've also tried array[i] = 0, array[i] = NULL.

Everything I have tried it's not effecting the values of the array and they won't clear.

I assume it's not working because it is actually a 2D array, I'm just stuggling how to clear it.

Thank you very much for any help!!

*array[20] is not a 2D array but an array of pointers to char(s); can you post more of the relevant code.

That is correct. My array is full of strings. Sorry for my bad description. An example of my array is

array[0] - hello
array[1] - world

how do I then go about clearing 'array' so they no longer hold those words.
Thank you

Depends on what you mean by "clearing". It is a 1D pointer array, so you could set the pointers to an empty string, perhaps, or NULL?

That would be fine. I just need array[0] and array[1] to no longer equal the string they were. It just needs to be cleared so it won't be read. Just stores random data or anything.

In that case set each element of array[] to NULL; looking back at your first post you were doing that but were probably going out of bounds depending on the value of totalnumberofstrings.

I seem to pass totalnumberofstrings+1 and now it all works magically! wow. That means it works!! YAY!!! all these hours! and now it works!! That's why we all program, isn't it!!

Thank you for the general talking inspriation!!!

Many Thanks

So perhaps all but the last one wasn't getting cleared until you passed it totalnumberofstrings+1.
