So when you add 3 to an int *, you advance by three int s. …
NettetThese are called arithmetic operators. If we talk about this topic or if we talk about pointer arithmetic, with this topic we understand that on the pointer, some operation is going to be performed and how will that operation be, it will be of arithmetic type like addition, subtraction or this kind of operation, those we are going to perform. NettetArithmetic (from Ancient Greek ἀριθμός (arithmós) 'number', and τική [] (tikḗ [tékhnē]) 'art, craft') is an elementary part of mathematics that consists of the study of the properties of the traditional operations on …
NettetAs we discussed in the section Pointer Arithmetic, adding an integer to a pointer will increment the address it holds by the product of the integer and the data type’s size. The same is true if we add an integer to the name of an array. The following two statements are equivalent: *(pv + i) *(vector + i) NettetExample: On distributing 26 strawberries among 6 children, each child gets 4 strawberries, and 2 strawberries are left.
