project for Data structures. please do it with c++ codes. 1st write cpp file, then test it if its right with the help of test file. also provide compiling steps.

1) sequence1.cpp:

// FILE: sequence1.h // CLASS PROVIDED: sequence (part of the namespace main_savitch_3) // There is no implementation file provided for this class since it is // an exercise from Section 3.2 of "Data Structures and Other Objects Using C++" // // TYPEDEFS and MEMBER CONSTANTS for the sequence class: // typedef ____ value_type // sequence::value_type is the data type of the items in the sequence. It // may be any of the C++ built-in types (int, char, etc.), or a class with a // default constructor, an assignment operator, and a copy constructor. // // typedef ____ size_type // sequence::size_type is the data type of any variable that keeps track of // how many items are in a sequence. // // static const size_type CAPACITY = _____ // sequence::CAPACITY is the maximum number of items that a sequence can hold. // // CONSTRUCTOR for the sequence class: // sequence( ) // Postcondition: The sequence has been initialized as an empty sequence. // // MODIFICATION MEMBER FUNCTIONS for the sequence class: // void start( ) // Postcondition: The first item on the sequence becomes the current item // (but if the sequence is empty, then there is no current item). // // void advance( ) // Precondition: is_item returns true. // Postcondition: If the current item was already the last item in the // sequence, then there is no longer any current item. Otherwise, the new // current item is the item immediately after the original current item. // // void insert(const value_type& entry) // Precondition: size( ) < CAPACITY. // Postcondition: A new copy of entry has been inserted in the sequence // before the current item. If there was no current item, then the new entry // has been inserted at the front of the sequence. In either case, the newly // inserted item is now the current item of the sequence. // // void attach(const value_type& entry) // Precondition: size( ) < CAPACITY. // Postcondition: A new copy of entry has been inserted in the sequence after // the current item. If there was no current item, then the new entry has // been attached to the end of the sequence. In either case, the newly // inserted item is now the current item of the sequence. // // void remove_current( ) // Precondition: is_item returns true. // Postcondition: The current item has been removed from the sequence, and the // item after this (if there is one) is now the new current item. // // CONSTANT MEMBER FUNCTIONS for the sequence class: // size_type size( ) const // Postcondition: The return value is the number of items in the sequence. // // bool is_item( ) const // Postcondition: A true return value indicates that there is a valid // "current" item that may be retrieved by activating the current // member function (listed below). A false return value indicates that // there is no valid current item. // // value_type current( ) const // Precondition: is_item( ) returns true. // Postcondition: The item returned is the current item in the sequence. // // VALUE SEMANTICS for the sequence class: // Assignments and the copy constructor may be used with sequence objects. 

2) sequence1.h:

#ifndef MAIN_SAVITCH_SEQUENCE_H #define MAIN_SAVITCH_SEQUENCE_H #include  // Provides size_t namespace main_savitch_3 { class sequence { public: // TYPEDEFS and MEMBER CONSTANTS typedef double value_type; typedef size_t size_type; //typedef std::size_t size_type; static const size_type CAPACITY = 30; // enum {CAPACITY = 30}; // // CONSTRUCTOR sequence( ); // MODIFICATION MEMBER FUNCTIONS void start( ); void advance( ); void insert(const value_type& entry); void attach(const value_type& entry); void remove_current( ); // CONSTANT MEMBER FUNCTIONS size_type size( ) const; bool is_item( ) const; value_type current( ) const; private: -- Fill in your private member variables here. -- Read Section 3.2 for guidelines. }; } #endif 

3) sequence_test.cpp

// FILE: sequence_test.cxx // An interactive test program for the new sequence class #include  // Provides toupper #include  // Provides cout and cin #include  // Provides EXIT_SUCCESS #include "sequence1.h" // With value_type defined as double using namespace std; using namespace main_savitch_3; // PROTOTYPES for functions used by this test program: void print_menu( ); // Postcondition: A menu of choices for this program has been written to cout. char get_user_command( ); // Postcondition: The user has been prompted to enter a one character command. // The next character has been read (skipping blanks and newline characters), // and this character has been returned. void show_sequence(sequence display); // Postcondition: The items on display have been printed to cout (one per line). double get_number( ); // Postcondition: The user has been prompted to enter a real number. The // number has been read, echoed to the screen, and returned by the function. int main( ) { sequence test; // A sequence that well perform tests on char choice; // A command character entered by the user cout << "I have initialized an empty sequence of real numbers." << endl; do { print_menu( ); choice = toupper(get_user_command( )); switch (choice) { case '!': test.start( ); break; case '+': test.advance( ); break; case '?': if (test.is_item( )) cout << "There is an item." << endl; else cout << "There is no current item." << endl; break; case 'C': if (test.is_item( )) cout << "Current item is: " << test.current( ) << endl; else cout << "There is no current item." << endl; break; case 'P': show_sequence(test); break; case 'S': cout << "Size is " << test.size( ) << '.' << endl; break; case 'I': test.insert(get_number( )); break; case 'A': test.attach(get_number( )); break; case 'R': test.remove_current( ); cout << "The current item has been removed." << endl; break; case 'Q': cout << "Ridicule is the best test of truth." << endl; break; default: cout << choice << " is invalid." << endl; } } while ((choice != 'Q')); return EXIT_SUCCESS; } void print_menu( ) // Library facilities used: iostream.h { cout << endl; // Print blank line before the menu cout << "The following choices are available: " << endl; cout << " !
