The purpose of this lab is to help reinforce container class concepts in C++. Specifically, the lab is to implement the sequence class from chapter 3. You should use the author's header file sequencel.h and the author's test program (sequence_exam.cpp) You are provided with a partially implemented file sequence1.cpp. Please implement the following the header file for this class. void advance0 void attach const value_type& entry) void remove currentO Move all files to the cloudland server and compile them using the following command g+ sequence_exam.cpp sequencel.cpp -o sequencel The purpose of this lab is to help reinforce container class concepts in C++.
