THIRD GENERATION PROGRAMMING LANGUAGE
The third generation of programming language, 3GL, or procedural language uses a series of English-like words, that are closer to human language, to write instructions.
High-level programming languages make complex programming simpler and easier to read, write and maintain.Programs written in a high-level programming language must be translated into machine language by a compiler or interpreter. PASCAL, FORTRAN, BASIC, COBOL, C and C++ are examples of third generation programming languages.
FOURTH GENERATION PROGRAMMING LANGUAGE
The fourth generation programming language or non-procedural language, often abbreviated as 4GL, enables users to access data in a database. A very high-level programming language is often referred to as goal-oriented programming language because it is usually limited to a very specific application and it might use syntax that is never used in other programming languages. SQL, NOMAD and FOCUS are examples of fourth generation programming languages.
FIFTH GENERATION PROGRAMMING LANGUAGE
The fifth generation programming language or visual programming language, is also known as natural language. Provides a visual or graphical interface, called a visual programming environment, for creating source codes. Fifth generation programming allows people to interact with computers without needing any specialised knowledge. People can talk to computers and the voice recognition systems can convert spoken sounds into written words. Prolog and Mercury are the best known fifth-generation languages.
