structExample {inta;intb;intc; }; If we create a new Example array Example* test =newExample[3]; Then test will be a pointer to the first element in the array. Lets assume thatsizeof(int) == 4andarr == 0x1000 *arr (or *(arr+0)) will get us the first array element at locat...
Otherwise, the result is a pointer to the object or function designated by its operand. §6.5.6, paragraph 8: When an expression that has integer type is added to or subtracted from a pointer, the result has the type of the pointer operand. If the pointer operand points to an element o...

can’t be negative, using an unsigned type allows arrays of greater length due to the extra bit (something that was important in the 16-bit days), and range-checking the subscript requires one conditional check instead of two (since no check was needed to ensure the index was less than ...
Mind though, when the operator function is declared as a member function, it has the first parameter bound to implicit this pointer. Thus, we can have one less parameter than the operands for operator overloads declared as member functions. #include <iostream> #include <string> #include <...
In the above example, note that the implementations ofint& IntList::operator[](int)andconst int& IntList::operator[](int) constare identical. The only difference is the return type of the function. In cases where the implementation is trivial (e.g. a single line), it’s fine (and pr...
The only error that is coming up is: "expression must have pointer-to-object type"/"subscript requires array or pointer type". The arrays I did for the previous project looked the exact same and they were fine. The instructions call for functions to return the array values. Any help would...
