Consider the following statements:
int *pFarr, *pVarr;
int farr[3] = {11,22,33};
int varr[3] = {7,8,9};
pFarr = &(farr[0]);
pVarr = varr;
At this stage, both pointers are pointing at the start of each respective array address. For *pFarr, we are presently looking at 11 and for *pVarr…

Incase of pointer arithmetic, are the integers automatically converted to their signed variants? If yes, why?
Suppose I do
pointer + uiVal
where pointer is a pointer to int and uiVal is initialized to -1, then I find that the address in pointers get decremented by 4. Why is the unsigned value…

Is there a way to figure out where in an array a pointer is?
Lets say we have done this:
int nNums[10] = {'11','51','23', ... }; // Some random sequence
int* pInt = nNums[4]; // Some index in the sequence.
...
pInt++; // Assuming we have lost track of the index by this…

Having code:
int** a = new int*[2];
a[0] = new int(1);
a[1] = new int(2);
cout << "a[0] " << a[0] << '\n';
cout << "a[1] " << a[1] << '\n';
cout << "a[2] " << a[2] << '\n';
cout << "a[0] + 1 " << a[0] + 1 << '\n';//WHY THIS…
