Our common data types in STL program is Char Int String, etc. To use complex data types (class types), you must override the necessary operators. The next example demonstrates this:
#include #include Using Namespace std; // Reserved x == rhs.x && this-> y == rhs.y && this-> z x == rhs .x && this-> y x Sortit (List & mylist) {mylist.sort (); return mylist;} main () {list mylist, sortedlist; cmyclass myclass; myclass.x = 3; myclass.y = 2; Myclass.y .z = 'a'; mylist.push_back (myclass); myclass.x = 2; mylist.push_back (myclass); myclass.z = 'b'; mylist.push_back (Mycla SS); myclass.x = 1; myclass.y = 5; myclass.z = 'c'; mylist.push_back (myclass); list :: item i; for (i = myList.begin (); i ! = mylist.end (); i) {cout << ""; myclass.print (* i);} cout << Endl; sortedList = sortit (mylist); cout << "sorted: << ENDL For (i = sortedlist.begin (); i! = Sortedlist.end (); i) {cout << "; myclass.print (* i);
} Cout << endl; return 0;} output:
3 2 A 2 2 A 2 2 B 1 5 C
Sorted: 1 5 C 2 2 A 2 2 B 3 2 A
