The correspondence between indexing and pointer arithmetic is very close. By definition, the value of a variable or expression of type array is the address of element zero of the array. Thus after the assignment pa = &a[0]; pa and a have identical values. Since the name of an array is...
Yeah, [] hints that the argument will be treated as an array, but so does a plural name like requests, so do that instead. Always prefer array indexing over pointer arithmetic If you're working with an array of things, treat them as an array. Pointer arithmetic is confusing and bug-pro...

The compiler keeps the buffer size and uses it to control pointer arithmetic of pointers that are assigned to the buffer later. You can perform operations on circular pointers with the usual C pointer arithmetic with the difference that the pointer will wrap. When you acces the circular buffer ...
Instead of writing array[index], you can write index[array]:int ft_strlen(char *str) { int i = 0; while (i[str]) ++i; return i; }Because this is understood by the compiler as pointer arithmetic:int ft_strlen(char *str) { int i = 0; while (*(str+i)) ++i; return i; }...
So watch out your pointer arithmetic carefully, what worked in 32-bit mode might fail in 64-bit mode. Translate 0 Kudos Copy link Reply barakobama Beginner 04-02-2008 02:04 PM 1,570 Views Thanks for your reply. My question was: How can I access to an address with...
For example, this VCOP Kernel-C statement: Vdst = unpack(Vsrc1, Vsrc2); translates to: bit_unpack::apply(Vdst, Vsrc1, Vsrc2); The element type is specified by the template parameter int. All arithmetic classes have a single method called apply() that implements the translation. In ...
