int array[SIZE];
public:
Example()
{
register int k;
for (k = 0; k < SIZE; k++)
{
array[k] = k;
}
}
int &operator[](int k)
{
if (k > SIZE)
{
cout << " Index out of bounds" << endl;
return array[0];
}
return array[k];
}
};
int main()
{
Example Object;
cout << Object[10];
cout << Object[20];
return 0;
}
