List Operations
list | splice | // it points to 2 | mylist1: 1 2 3 4 |mylist2: 10 20 30 mylist1.splice (it, mylist2); // mylist1: 1 10 20 30 2 3 4 | mylist2 (empty)|"it" still points to 2 mylist2.splice (mylist2.begin(),mylist1, it); // mylist1: 1 10 20 30 3 4 | mylist2: 2 | "it" is now invalid. mylist1.splice ( mylist1.begin(), mylist1, it, mylist1.end()); //"it" points now to 30 | mylist1: 30 3 4 1 10 20 |
remove | mylist.remove (value); | |
remove_if | mylist.remove_if (function); mylist.remove_if(class()); |

unique | bool same_integral_part (double first, double second) { return ( int(first)==int(second) ); } mylist.sort(); // 2.72, 3.14, 12.15, 12.77, 12.77, // 15.3, 72.25, 72.25, 73.0, 73.35 mylist.unique(); // 2.72, 3.14, 12.15, 12.77 // 15.3, 72.25, 73.0, 73.35 mylist.unique (same_integral_part); // 2.72, 3.14, 12.15 // 15.3, 72.25, 73.0 |
