In this section, we will use the vector array and pv pointer as defined below: int vector[5] = {1, 2, 3, 4, 5}; int *pv = vector; The code generated by vector [i] is different from the code generated by vector+i. WebPersonally, I think of pointers as (sometimes) pretending to be arrays rather than visa versa. In many other languages, pointers don't have array-like behaviour - if you want to access an array through a pointer you either use a pointer-to-array type or you do pointer arithmetic (counting in bytes, not elements).
