Pointers

Arrays and Pointers

The name of an array is a pointer to the starting element.

int a[10];
int* p = a; // now p points to a[0];
*a = 12; // same as a[0] = 12;

You can add an integer to offset to the pointer to point to another array location (pointer arithmetic).
```
*(a + 3) means the same as a[3]
```
This relationship is called the array/pointer duality law. For any integer n,
```
*(a + n) means the same as a[n]
```
