array indexing vs pointer arithmetic

Nov 9th, 2008

 Help with Code Tags 
 C++ Syntax (Toggle Plain Text) 
int x[5];
x[4] = 10;
*(x + 4) = 10;
int x[5];
x[4] = 10;
*(x + 4) = 10;

Array indexing has a cleaner syntax but (as I've read) pointer arithmetic is faster. My question is, is it worth to use pointer arithmetic? Is there a noticeable difference?
