  1. Tutorial 3More C++ and ADT

  2. Admin • Some students have moved to different class • Changes have been reflected in the attendance list • See the last few lines • Compare this scenario with our question 2… • If I put these students (who moved to different group) in alphabetical order, I need to shift the rest downwards • I do not want to print the attendance list again… • No more swap request will be entertained • Please try to achieve 100% attendancein your respective class

  3. Error Handling (in C++) • When a (runtime) error happens… • There are many ways to handle it… • Print error message, • Re-do the task, • Quit program, etc • Using “throw and catch”… • We will see this in action later in Q1 • “throw and catch” is also available in Java

  4. Abstract Data Type (ADT) • Abstract Data Type • Data + Operations (Algorithms) to organize that data structure • Data Structure: “Structure of Data”, structure makes life easier • Algorithm: Step by step way to solve certain problem • Walls: We do not need to know the implementation details • Examples: Complex Number, Sphere, ColoredSphere:Sphere, List, etc • Wait! Contradictions? • We are given so many implementation details here! Why bother? • In fact, we are going to do that throughout this module  • To give you a strong theoretical foundation… • Later on, you will just use these ADTs for your programming tasks • Like C++ STL

  5. C++ Standard Template Library • C++ has Standard Template Library (STL) • This library can simplify your life… • Reference: • http://www.cppreference.com • Today’s topic is STL Vector • Your friend who do Q2 will show some ideas • Throughout the semester, we will learn more

  6. Classes in C++ to Implement ADT • Basic pattern: • In “header file”  *.hclass C {} { public: // the opening in the wall… // put constructor/destructor and public methods here (accessor/mutator/etc) private: // put hidden attributes or local methods here}; • In “implementation file”  *.cpp#include “header_file_name.h”C::C() { // constructor here }C::~C() { // destructor here }C::methodname() { // implementation here }

  7. Student Presentation (Q3 longer…) • T5: • LAU WAI HOE AARON • LEONARDUS ADI PRASETYA • LI JIALONG • T10: • HU FAN • IMANTHI UDESHINI D B • JIANG YONGBO • T13: • FAN LANLAN • GAO MINMIN • HAO SHUAI • T9: • HOO CHIN HAU • KALYANI IYER • KOAY ZI HAO • T17 • CHENG LULU • CHEW JIE BIN ELROY • CHONG LEE KEE
