Computer project work [viii]2008 09

  1. 1.       Program Programming language Compiler Interpreter Example of programming languages Evolution of programming languages.
  2. 2. A program is a sequence of instruction written In a language that the computer can understand and there by process .The individual set of such sequences of instruction or a collection of such set can be turned as programs .
  3. 3. Programming Languages is a set of grammatical rules for instructing a computer to perform specific tasks. Example of programming Language are BASIC, C,C++, COBOL, FORTRAN and Pascal. Each language has a unique set of keywords and a special syntax for organizing program instructions programming language can be divided into two levels.
  4. 4. Programming Language Low Level Language High Level Language
  5. 5. Low Level Language High Level Language These language are directly linked with computer can understand these languages and therefore , are called Low Languages. These Languages are much closer to human language code and were developed to make programming easier. The dependency of these languages is on interpreter and complier so that the computer can understand and process whatever is instructed in High Level Language.
  6. 6. COBOL – Common Business Oriented Language – This was , at one time ,the most common commercial language . COBOL was complier for translation . FORTRAN- Formula Translation – An engineering and specific based language. It was developed in 1957 by international Business Machines (IBM). ALGOL- Algorithmic Language – It is used for both scientific and engineering purposes. BASIC- Beginners All –purpose Symbolic Instruction Code – As the name suggests , it is an all- purpose high level language . It was developed at Dartmouth College , USA , in the early 1960s .
  7. 7. A Complier is a program that translates a source program written in a high Level Language [such as a] into machine code for the appropriate computer hardware. The Program can then be executed on any computer without the need of complier. A complex reads the complete program checks for the error and reports it after the error have been removed it converts the Program into an executable program which can be run on any machines without the need of Complier.
