Difference Between *(Pointer + Index) and Pointer[]

Question

int* myPointer = new int[100];  // ...  int firstValue = *(myPointer + 0); int secondValue = myPointer[1]; 

Is there any functional difference between *(myPointer + index) and myPointer[index]? Which is considered better practice?

Answer 1

Functionally, they are identical.

Semantically, the pointer dereference says "Here's a thing, but I really care about the thing X spaces over", while the array access says "Here's a bunch of things, I care about the Xth one."

In most cases, I would prefer the array form.
