      of the old array, delete the old array, reassign pa to the new array, and finally return a reference to the element at index. Set nextIndex 1 past index if necessary. The return type of int& is the reference and is obtained by dereferencing the pointer pa, incremented by index. If we returned a pointer, it would have to be dereference it

      If you declare something as an array of a particular type, you can use it as a pointer to that type, and vice versa. • For example, if you declare an array int list[100]; the C++ compiler treats the name list as a shorthand for the expression &list[0]. When you pass an array to a function, only the address of the array is copied into the ...

      1. To calculate the address of element array[i], we calculate (base address of array) + i * 4 for an array of words. Since multiplication is a slow operation, we can shift i’s value left two bit positions. For example: ADR r3, ARRAY # load base address of ARRAY into r3 (ARRAY contains 4-byte items) LDR r2, I # load index I into r2
