1. Implement a singleton class
class {MySingleton
public:
static MySingleton* const p_single;
private:
MySingleton(void){cout << "private constructor." << endl;} // private constructor
MySingleton(const MySingleton&){} //private copy-constructor
MySingleton & operator = (const MySingleton &) {} // assignment preventives
};
MySingleton* const MySingleton::p_single = new MySingleton(); // private constructor will be called once
int main () {
return 0;
}
the output will be: ( order matters)
private constructor.
