C++

• C++ programs should be called name.cpp, where name is replaced with the name of your program. (or name.cc)
• Single programs have many  individual .cpp files.

• C++ compiler takes the source code as input and produce a machine language object file as output.  (name.o or name.obj)
•  5 cpp files -- >> 5 obj files
• Linux and Mac OS X systems come with a C++ compiler called g++
• In some OS environments a makefile, which is a file that tells the compiler which files to compile.  

• Linker takes all the object files for a program and combine them into a single executable.             e.g: g++ -o prog file1.o file2.o file3.o

• Free IDE s : Microsoft’s Visual C++ 2005 Express Edition, and Code::Blocks. 
• On a windows machine we can use a free ms 2010 Visual C++ 
• Also Eclipse...

   

• Eg Program :

#include

int main()

{

    using namespace std;

    cout << "Hello world!" << endl;

    return 0;

}
