Computer Terms Review from what language did C++ originate? what’s input, output device? what’s main memory, memory location, memory address? what’s a program, data? what’s natural language, high-level language, machine language what’s compiler, linker, library? what’s source/object/executable code? what are syntax/semantic/stylistic rules?

The Fundamentals of C++ First programs Development Environment

Program Organization program structure first programs hello, world calculating the area of a rectangle Microsoft Visual Studio subversion

Programming Cycle Program written in human-readable form is called source program - extension - .cpp (helloworld.cpp) compiler is applied to the source program to translate it into form machine understands - we use Microsoft’s Visual C++ compiler (part of Microsoft’s Visual Studio) compiler may produce either object code - direct translation of the source program - extension o. (helloworld.o) compiler (actually linker) adds all other necessary parts for the program to run on a computer and produces executable code specially produced executables can be traced (more on that later)

First Program: helloWorld.cpp // displays a greeting // Mikhail Nesterenko // 8/25/2013 #include <iostream> using std::cout; using std::endl; int main() { cout << "Hello, World!" << endl; } preprocessor directive comments function named main() indicates start of program output statement

Visual Studio Microsoft Visual Studio (MSVS) is an integrated development environment (IDE) for writing, debugging, testing and running programs, supports multiple languages C++ is one of the supported languages MSVS basic concepts console application (command line application, Win32) - input/output go to console project - a set of files that are developed jointly. A project compiles into a single executable solution – a set of related projects

Subversion subversion – version control software used by programmers for team code development. We use for lab submission and grading has centralized code repository C++ projects can be: added to repository, checked out and committed repository is accessible from the web  method to verify submission TortoiseSVN – subversion client integrated into Windows Explorer
