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 3

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) 4

First Program: helloWorld.cpp

preprocessor directive // displays a greeting // Mikhail Nesterenko // 8/25/2013 #include function named main() indicates start of program comments using std::cout; using std::endl; int main() { cout << "Hello, World!" << endl; } output statement 5

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 6



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 7
