WebAddress Arithmetic In C, we have something like: char name[10]; This reserves ten bytes of memory and the first one is called name[0]. In assembly language we can do it a number of ways. The first thing to ask, is the data going to be initialized or not. Web2. You can do arithmetic with pointers. Only be aware that the "unit" is not 1 but the size of the pointed object. So if p is a pointer to integer the difference in addresses between p+1 and p could be 4 bytes or more. If you want to do arithmetic with addresses you should use pointers to char or convert them to such pointers. 3d photo iphone xr WebMay 29, 2024 · Two integer pointers say ptr1(address:1000) and ptr2(address:1004) are subtracted. The difference between address is 4 bytes. Since the size of int is 4 bytes, therefore the increment between ptr1 and ptr2 is given by (4/4) = 1.
