Computer Languages.

  1. 1. Computer Languages Presented By :- Aditya Sheoran
  2. 2. Definition Of Computer Languages • Computer languages are the languages by which a user command the computer to work on the algorithm which a user has written to het an output. • Two types of computer languages:-
  3. 3. Low Level Language 1. First Generation. 2. Second Generation.
  4. 4. First Generation Language (1GL) • Represent the very early, primitive Computer languages that consisted entirely of 1’s and 0’s- The actual language that the computer understands (machine language)
  5. 5. Second Generation Language (2GL) Represent a step up from the 1GL. Allow for the use of symbolic names instead of just numbers. Second Generation languages are known as assembly languages. Code written in an assembly language is converted into machine language (1GL)
  6. 6. High Level Languages • High Level programming languages allow the specification of a problem solution in terms closer to those used by human beings. These languages were designed to make programming far easier, less error-prone and to remove the programmer from having to know the details of internal structure of a particular computer. This language is used in third generation.
  7. 7. Third Generation Language (3GL) • With the languages introduced by 3GL of computer programming , words and commands were being used. These languages therefore, had syntax that was much easier to understand. Third Generation Languages are known as “High Level Languages”.
  8. 8. TYPES • C++ • Visual Basic • Java • Java script
  9. 9. C++ • C++ is statically typed, free-form, multi paradigm compiled, general purpose programming language. It is regarded as a “Middle Level Language” as it comprises a combination of both high and low level language features. • Language Features:- 1. Operators and operator overloading. 2. Templates. 3. Objects. 4. Polymorphism.
  10. 10. Visual Basic • Visual Basic is the third generation event-driven programming language and integrated development environment (IDE) from Microsoft for its COM programming Model. Visual Basic is relatively easy to learn and use.
