STL Function n Little bit of Strings

STL - SET

Intialization

SET

set<int> myset;

SET Iterator

set<int>::iterator it;

Insertion in SET

myset.insert(value);

Deletion in SET

myset.erase(value);
|
it=myset.find(value)
 myset.erase(it,myset.end()); //to remove all element >=value 

Traversing in SET

for(it=myset.begin();it!=myset.end();it++)
 cout<<(*it);

Lower_bound in SET

it=myset.lower_bound(value);
//return an index >=value.

Upper_bound in SET

it=myset.upper_bound(value);
//return an index >value.
//Note if there is no answer >=value then it return the iterator to my.end();

String Operation

string h;
h.find(“-”); //return the index where the charater is found.
h.erase(pos,number_of_character_to_be_erased);
h.erase(pos);//erase the character in that index
