Making an array of Objects and using overloaded [] in c++

I created this class, say, Apple, and it has an overloaded operator [].
Then in another class, I made an array of apples, Apple stack[10].
Then when I was using stack[2] in an expression, instead of stack[2] being an object, the compiler is acting like it sees stack as stack[0], and then calling the operator [] and its parameter as 2.

Could you suggest a way I could calling stack[2] without being that way?

Providing the code would have been helpful.

However, suppose you have a variable x in the class Apple. You can access it using (stack+2)->x. This would work same as stack[2].x. And in case you want to use your overloaded operator, you may use it similarly. This wont confuse the compiler.

Based on the information given so far, stack[2] refers to an Apple object. You can also do stack[2][5] to call the overloaded operator[] in your Apple class.

You could use a pointer to get array elements:

*(stack+2)[3]; // lookup element 2 and call its [] operator with 3
