8. Development Environment How to write, build, and run code Quick History of C++ Variables and Types Module Overview

9. Lesson 1 – Development Environment Development Environment

10. Visual Studio Express 2013 for Windows Desktop –It’s free and it’s all you need to follow along Not using Windows? –C++ works on other platforms too –http://isocpp.org/get-started has links to compilershttp://isocpp.org/get-started Our sample code is available –LINK TBA

11. DEMO Hello, World!

12. Lesson 2: How to Write, Build and Run Code How code is built Structure of a C++ program Debugging

13. The Compilation Process Preprocessor Takes your C++ source code and evaluates preprocessor directives. Produces a preprocessed source file (but usually is just part of compiler). Compiler Takes preprocessed source code, compiles into object files. Checks that your code conforms to all syntax and semantic rules (e.g., no type errors). Accepts promises from the code about things defined in other source files. Linker Takes object files, links them into an executable program. Ensures that all of the promises to the compiler are kept.

14. Structure of a C++ program #include int main() { std::cout << "Hello, World!" << std::endl; return 0; } Use a library Special function name that the OS calls to run your program std::cout represents console output << means send the next thing to it

15. DEMO Building

16. Debugging Normally a console application –Starts –Executes the code in main() –Might print to the console (or read from the keyboard) –Terminates (quits) Under a debugger, you can pause execution –Inspect values –Watch execution proceed –Slower, but vital to understanding

17. DEMO Debugging

18. Lesson 3: Quick History of C++ Born in 1979 as C with Classes –Retains backward compatibility with C Named C++ in 1983 Ratified as ISO standard in 1998 Continues to change under stewardship of a standards committee

19. Lesson 1: Types C++ is strongly typed Fundamental types Casting (changing type)

20. DEMO Types

21. Fundamental Types Types you use a lot: –int, unsigned int –double –bool Types you may see –char, unsigned char –long, unsigned long –short, unsigned short –float http://msdn.microsoft.com/en-us/library/cc953fe1.aspx

22. Casting Instead of writing code that relies on the compiler to convert one type to another, you can ask for it explicitly i = static_cast (3.2); Makes a good “signpost” for others who read your code Takes away compiler warnings –Always try to build warning free

23. DEMO Casting
