You Why programming? Why C++? What are my expectations from this class? Am I eligible? Am I ready? Prerequisite: C- or better in COP 3014 (or equivalent classes) How to get a CS account? (Resource page) Is COP 3330 hard and challenging? How to ace this class? How to pass this class? How to fail this class? Please read carefully the course policy and the academic honor policy in FSU What’s next after COP 3330?

Why Programming? Why programming is important? https://www.youtube.com/watch?v=Dv7gLpW91DM A new way of thinking and communication A human creative skill acquired by experience Leverage computers/machines to solve problems Science & art Interesting and challenging opportunities to disrupt our life Decent jobs and bright futures ……

Why C++? Popularity TIOBE Index, January 2019

Why C++? Companies

Why C++? Browsers

Why C++? Software

Why C++? Games (Almost Universally)

Why C++? Machines The F-35 Lightning II (Joint Strike Fighter) relies extensively on C++ The Spirit rover was operational for over 6 years when the mission was only planned to run for around 3 months

Why C++? When performance becomes the number one principle When you want to fully control your software/systems When you want to clearly know how computer resources are used …… n. When your boss asks you to do so … So in the right hands its speed and ability to cheaply use resources should be able to surpass other languages!

Why NOT C++? God damn hard! Poor readability and portability “The problem that I have with them today is that... C++ is too complicated.” by Donald Knuth “It does a lot of things half well and it’s just a garbage heap of ideas that are mutually exclusive.” by Ken Thompson Poor readability and portability Lack full-featured standard libraries Lack of reflection, garbage collection, verbose error messages (particular from template metaprogramming) ……

Ken Thompson and Dennis Ritchie, creators of the C language A Brief C++ History K&R created C in 1972 Fast, simple, cross-platform  No objects or classes  Difficult to write code that work generically Tedious when write large programs In 1983, C++ was created by Bjarne Stroustrup Allow the programmer full control if they want it Don’t sacrifice performance except as a last resort Only add features if they solve an actual problem Enforce safety at compile time whenever possible …… Ken Thompson and Dennis Ritchie, creators of the C language

Our First C++ Program: hello.cpp #include <iostream> int main() { std::cout << "Hello world!" << std::endl; return 0; } Talk is cheap. Show me the code. --- Linus Torvalds
