non-commutative example of a program

converts from meters to inches This program will convert from meters to inches or convert units from meters to inches by formula number that we input of the meter will be changed to cm that is at times 100 and the switch to inch the alteration was in for 2.54 #include <iostream> #include <stdlib.h> using namespace std; class konversi{ friend ostream& operator<<(ostream&, const konversi&); friend istream& operator>>(istream&, konversi&); public: konversi(); void konversi_inchi(){inchi=((m*100)/2.54);} private: float m; float inchi; }; konversi::konversi(){} istream& operator>>(istream& in, konversi& masukan){ cout<<”masukan berapa meter: “; in>>masukan.m; masukan.konversi_inchi(); return in; } ostream& operator<<(ostream& out, const konversi& keluaran){ out<<”nilai m : “<<” ( “<<keluaran.m<<” *100 cm ) /2,54″<<endl; out<<keluaran.m<<” m : “<<keluaran.inchi<<” inchi “<<endl; return out; } int main(int argc, char *argv[]) { konversi X; cin>>X; cout<<X; system(“PAUSE”); return 0; }
