making it simple...
According to these guidelines, we can write:
pa = &a[4];
x = *(pa + 3);
y = *pa + 3;
Also, you need to be careful with operator precedence:
*pa++;
(*pa)++;
Following examples are also valid, but better avoid this syntax as it can make the
code really illegible:
(a + 1)[i] = 3;
// same as: *((a + 1) + i) = 3, i.e. a[i + 1] = 3
(i + 2)[a] = 0;
// same as: *((i + 2) + a) = 0, i.e. a[i + 2] = 0
Assignment and Comparison
You can use a simple assignment operator (
another if they are of the same type. If they are of different types, you must use a
typecast operator. Explicit type conversion is not necessary if one of the pointers is
generic (of
Assigning the integer constant 0 to a pointer assigns a null pointer value to it. The
mnemonic
can be used for legibility.
Two pointers pointing into the same array may be compared by using relational
operators

int *pa = &a[4], *pb = &a[2];
if (pa > pb) {
// this will be executed as 4 is greater than 2
}
