C-Programming: What happens if I increment an Arraypointer while passing it as an argument

Question

Will this work? I expect

foo(myArraypointer + 10);

be the same as

foo( &(myArraypointer[10]));

will this be treated as same for most compilers? Is this considered good or bad practice and why? What could go wrong?

Answer 1

For any pointer or array a and index i, the expression a[i] is equal to *(a + i). That means that &a[i] is equal to &*(a + i), where the last can be shortened to a + i.
