Is there any way to overload the array subscript operator in C++ other than in a class? I would like to call a user-defined function when reading/writing in the array.
For example:
int* array = new int[10];
array[0] = 5;
When writing in array[0], I would like to call my own function. I know it can be done inside a class by overloading the operator[] (for example, a SafeArray class).
Thanks.
What you want is a wrapper class, something like:
template<typename T>
struct SubscriptWrapper {
SubscriptWrapper(T* array) : array_(array) {};
T& operator[](size_t index) {
// your magic goes in here
};
T* array_;
}
