      Goals
       To be able to write simple C/C++ programs
       To be able to understand and modify existing C/C++ 
        code
       To be able to write and use makefiles

       Compiled vs. Interpreted Languages
        Interpreted languages
            when you type something, e.g., “x=y+z”, it is immediately converted 
             to machine language and executed
            examples:  Matlab,  Python
            advantage
               lots off convenient features
            disadvantage
               can be slow and memory-intensive
                                                                       4

     Compiled (cont’d)
      Compiled languages
         examples: C,  C++,  Fortran
         source code is written using a text editor
            source code does nothing by itself – it’s just text
            we will use source file suffix .cpp
         source code must be processed through a compiler
            translates source code into machine language
            creates executable
               this is the code that you actually run
               like .exe file in Windows
                                                      5

       C History
        Developed by Dennis Ritchie at Bell Labs in 1972
            Originally designed for system software
            Impetus was porting of Unix to a DEC PDP-11
                PDP-11 had 24kB main memory!
        1978 book “The C Programming Language” by 
          Kernighan & Ritchie served as standard
        Official ANSI standard published in 1989
            Updated in 1999
                                                                        6
