allocate memory for an array

[youssef]

Hi,
I would like to create a Array and allocate memory dynamicly.
How can I do ?



BYTE *pArray;
pArray = new BYTE[6];
pArray+0;
*pArray = 1;
pArray+1;
*pArray = 2;
m_edit2 = *pArray;
pArray+1;
m_edit3 = *pArray;
delete [] pArray;

You have many choices:
BYTE *pArray;
pArray = new BYTE[6];
*pArray = 1;
pArray += 1;
*pArray = 2;
m_edit2 = *pArray;
pArray += 1;
*pArray = x;
m_edit3 = *pArray;
delete [] pArray;
////////////or/////////////////////
BYTE *pArray;
pArray = new BYTE[6];
*pArray = 1;
*(pArray + 1) = 2;
m_edit2 = *(pArray + 1);
*(pArray + 2) = x;
m_edit3 = *(pArray + 2);
delete [] pArray;
////////////or/////////////////////
BYTE *pArray;
pArray = new BYTE[6];
pArray[0] = 1;
pArray[1] = 2;
m_edit2 = pArray[1];
pArray[2] = x;
m_edit3 = pArray[2];
delete [] pArray; John Fill

see the first choice will generate a memory leak. After changing the pointer you should restore it:
pArray += 1;
//..do something
pArray -= 1;
delete[] pArray; John Fill
