  • What are 4GL languages?

    A fourth-generation programming language (4GL) is any computer programming language that belongs to a class of languages envisioned as an advancement upon third-generation programming languages (3GL).

  • Is C++ a 4GL?

    4GLs are usually not general-purpose languages like third-generation languages such as C and C++ are but instead are usually designed for a specific purpose, as in the case of SQL, which works with databases.

  • Is 4GL a low level language?

    The fourth-generation languages, or 4GL :
    Fourth generation languages are also known as very high level languages. They are non-procedural languages, so named because they allow programmers and users to specify what the computer is supposed to do without having to specify how the computer is supposed to do it.
  • 4GLs are sometimes called problem-oriented languages or non-procedural languages, and require less training than 3GLs. In these languages one tells the computer what to do, not how to do it. Programmers and end-users use 4GLs to develop software applications. Some examples are SQL, ACCESS, Informix and FOCUS.
