/* The following program is a futile (and worthless) attempt to create a class that works like the 'var' keyword in JavaScript and other languages. Currently, the 'var' type can only be 'assigned' data of different 'primitive' types. The future additions that are being worked on: 0) Retrieve the value using a member function (map against type). 1) Provide basic operators for use on 'var' variables. (like +=,-=,*=,/=,%=) 2) Allow storage of complex types like STL containers, etc., and provide a template support instead of the current approach. */ #include #include #include using namespace std; union space { char _char; int _int; bool _bool; float _float; double _dbl; long _long; long long _llong; }; class var { space u; string tn,_str; public: var(int a ) {u._int = a; tn = typeid(int).name(); } var(char a ) {u._char = a; tn = typeid(char).name(); } var(float a) {u._float = a; tn = typeid(float).name(); } var(double a) {u._dbl = a; tn = typeid(double).name(); } var(long a) {u._long = a; tn = typeid(long).name(); } var(long long a){u._llong = a; tn = typeid(long long).name();} var(bool a) {u._bool = a; tn = typeid(bool).name(); } var(string a) {_str = a; tn = typeid(string).name(); } var& operator=(int a ) {u._int = a; tn = typeid(int).name(); return *this; } var& operator=(char a ) {u._char = a; tn = typeid(char).name(); return *this; } var& operator=(float a) {u._float = a; tn = typeid(float).name(); return *this; } var& operator=(double a) {u._dbl = a; tn = typeid(double).name(); return *this; } var& operator=(long a) {u._long = a; tn = typeid(long).name(); return *this; } var& operator=(long long a){u._llong = a; tn = typeid(long long).name();return *this;} var& operator=(string a) {_str = a; tn = typeid(string).name(); return *this; } var& operator=(bool a) {u._bool = a; tn = typeid(bool).name(); return *this; } var& operator=(const var& v) { if(&v==this) return *this; else { u = v.u; tn = v.tn; _str = v._str; return *this; } } friend ostream& operator<<(ostream& o,var v) { //o<<"Currently Storing - "<"<"<
