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,
