Question

I have some questions about vector ;

• How can I append one vector in another end in time efficient way ?

• How can I sort one vector over using STL feature if type of it is NODE ? ( for NODE, look below )

  ex

  struct NODE {
  
             char name;
  
             .... // other things
  
  };

• std::vector::insert() can be used to insert from anything which uses the iterator protocol
• std::sort() sorts in ascending order and takes an optional comparison function (or anything with operator() on it) which takes elements a and b and should return true if a < b.
