How to use the vector::push_back and vector::pop_back Standard Template Library (STL) functions in Visual C++

   <vector>
				

   template<class _TYPE, class _A>
   void vector::push_back(const _TYPE& X);

   template<class _TYPE, class _A>
   void vector::pop_back();

// 
// Functions:
// 
//    vector::push_back - Appends (inserts) an element to the end of a
//                        vector, allocating memory for it if necessary.
// 
//    vector::pop_back -  Erases the last element of the vector.
// 
//    vector::begin - Returns an iterator to start traversal of the vector.
// 
//    vector::end - Returns an iterator for the last element of the vector.
// 
//    vector::iterator - Traverses the vector.
