Heavy Load () operator and heavy load forced type conversion

// After studying the half-host model, I finally figured out that // writing this test code can demonstrate the effect of class CConvert {public: CConvert () {m_nValue = 10;} // reload () operator int operator (); // overload int forced type conversion operator int (); protected: private: int m_nValue ;}; int CConvert: operator ()() {return m_nValue;} CConvert: operator int () {return m_nValue;} void SetValue (int nValue) {int nTest = nValue;} int main () {CConvert convert; setValue (convert); // call the forced type conversion overload character SetValue (convert (); // call the parentheses operator return 0 after the overload ;}
