#include <iostream> using namespace std; class Check { private: int i; public: Check(): i(0) { } void operator ++() { ++i; } void Display() { cout << "i=" << i << endl; } }; int main() { Check obj; // Displays the value of data member i for object obj obj.Display(); // Invokes operator function void operator ++( ) ++obj; // Displays the value of data member i for object obj obj.Display(); return 0; }
