How to Initialize an array of user selected size

[Deepak Samuel]

Hi, How do I initilaize an array whose size will be determined by an user input(For example from a edit box ? I tried this but they didnt work... numsamples = m_numsamp; const long arr = numsamples; ULONG x[arr]; ULONG y[arr]; They returned error 2057 and 2466. Thanks! Deepak Samuel.

You need to dynamically allocate your array. This is where pointers comes very handy!

ULONG* arrA = NULL;
int nSize;

// Get size of array from user
..
// allocate array to given size
arrA = new ULONG[nSize];
if(NULL != arrA)
{
   // work with array.
   arrA[0] = 1234;
   cout << _T("yeah baby!") << arrA[0] << endl;

   // don't forget to clean up when finished
   delete [] arrA;
{
