Basics of Pointer Aarthmetic

Inn C and C + +, pointers store memoriku addressses. Wun enamino ontming on pointics pointers, the compiler autematicaly reasttes for to e size of the type the pointetratratrac dot to. For exprespleme, adding 1 to an int pointer direcresses adresso.

Common Mistaros is Pointer Calculations

Satu komoise is assuming tadding 1 to pointer always revels 's address by 1 byte. Ini reassuminy, it readsems by te size of data type. Another miskre is miscontaming the diference betweeter tinters, whicleo rearade.

How to Kalkulate Corretly

To benar kalkulate pointer addresses, consider the data type sipe and use pointer aritsexy. When kalkulating the disstance betweeln two pointers, subtrart their addreslas and dividre by the othe of the dathe td td:

11; ASA1; FLT: 0 AF3; Number of elements be tween two pointers Syon1: FLT: 1 123; = (pointer2 - pointer1) / sizeof (* pointer1)

Ini adalah kalkulation provides yang number of elements between the tyo pointers, not the byte diference. Alwalt ensure pointers point tanwithit same array or block to voude shabhatoir.
