33 programming languages high level language imperative language object oriented language functional language scripting language assembly language machine language Fortrain, C, Pascal, hardware

34 Machine language a set of instructions executed directly by a CPU written in the form of 0 and 1 a computer can directly understand its own language

35 Machine language a set of instructions executed directly by a CPU written in the form of 0 and 1 a computer can directly understand its own language

36 assembly language low level language = use naturally understandable symbols called Mnemonics

39 procedural language = a list or set of instructions telling a computer what to do step by step C, Pascal, Fortran, BASIC,

40 procedural language = a list or set of instructions telling a computer what to do step by step C, Pascal, Fortran, BASIC, OOP = programming paradigm based on the concept of objects, which are data structures containing the data as fields (attributes) and code as procedures (methods) C++, Java, C#

41 procedural function definition and usage in the program top down no access specifier object oriented method and variables defined in class and used in objects bottom up access specifier: public, private, protected etc. procedural language = a list or set of instructions telling a computer what to do step by step C, Pascal, Fortran, BASIC, OOP = programming paradigm based on the concept of objects, which are data structures containing the data as fields (attributes) and code as procedures (methods) C++, Java, C#

42 C Ritchie C++ Stroustrup procedural yes OOP virtual function, polymorphism, overloading, namespace, inheritance no yes top down yes no multiple declaration of global variables yes no mapping between data and function used in objects no yes can call main() through other functions yes no all variables defined at the starting of a scope yes no

43 C++ compilers Windows: Visual Studio Bloodshed Dev-C Linux/Unix: GNU gcc e.g. g++ -o test test.cc
