Hi,

According to your description, if you want to overload [Subscript Operator ?

Here is a demo, I suggest you could refer to :

#include <iostream>  
using namespace std;  
const int SIZE = 9;  
  
class Array {  
private:  
	int arr[SIZE];  
  
public:  
	Array() {  
		register int i;  
		for (i = 0; i < SIZE; i++) {  
			arr[i] = i;  
		}  
	}  
  
	int &operator[](int i) {  
		if (i > SIZE) {  
			cout << "Index out of bounds" << endl;  
			// return first element.  
			return arr[0];  
		}  
  
		return arr[i];  
	}  
};  
  
int main() {  
	Array A;  
  
	cout << "Value of A[3…7] : " << A[3]<<","<< A[4] << "," << A[5] << "," << A[6] << "," << A[7] << endl;  
  
	return 0;  
}
