#include <iostream> #include <string> using namespace std; class Product//from www . j av a2s. c o m { private: int size; //related to constness mutable string owner; //not relevent to constness public: Product(int sz, string own) : size(sz), owner(own) { } void setSize(int sz) //changes size { size = sz; } void setOwner(string own) const //changes owner { owner = own; } int getSize() const //returns size { return size; } string getOwner() const //returns owner { return owner; } }; int main() { const Product sbar(60, "Window1"); // sbar.setSize(100); //can't do this to const obj sbar.setOwner("Window2"); //this is OK //these are OK too cout << sbar.getSize() << ", " << sbar.getOwner() << endl; return 0; }
