Allocating and releasing memory...

[MattWoberts]

Hi, I have this code which allocates a 2 dimensional array in C++:

        int subElements = 10;
	int ** myArray;
	myArray = (int **) new int*[lNumIntervals]; // Array of array pointers
		for (lTmp=0; lTmp<lNumIntervals; lTmp++)
	{
		myArray[lTmp] = (int *) new int[subElements];
		memset (myArray[lTmp],0,sizeof(int)*subElements);
	}

This works fine, and does the job. But in my code to release the array, I get a bad memory error (DAMAGE: After normal block). This is my code that causes the error:

	for (lTmp=0; lTmp<lNumIntervals; lTmp++)
	{
		delete [] myArray[lTmp];
	}
	delete [] myArray;

Any ideas? I'm a bit rusty on c++ so its stumped me!

Thanks.
Matt.

Darn,

Sorry all. Just as I posted this I found the solution.

In between the creation of the array and its cleanup, I had used memset to wipe it, but had gone beyond the size of the array with memset, hence nasty errors!

Aprppos: no need to cast new pointers implicitly in your case...
