Third-generation programming language

Third-generation programming language

A third-generation programming language is
a generational way to categorize high-level computer programming languages. Where assembly languages, categorized as second
generation programming languages, are machine-dependent, 3GLs are much more machine independent and
more programmer-friendly. This includes features like improved support
for aggregate data types, and expressing concepts in a way that favors the programmer, not the
computer. A third generation language improves over
a second generation language by having the computer take care of non-essential details. 3GLs feature more abstraction that previous
generations of languages, and thus can be considered higher level languages than their
first and second generation counterparts. First introduced in the late 1950s, Fortran,
ALGOL, and COBOL are early examples of this sort of language. Most popular general-purpose languages today,
such as C, C++, C#, Java, BASIC and Pascal, are also third-generation languages, although
C++, Java and C# follow a completely different path as they are object-oriented in nature. Third generation focused on structure and
had no meaning for the object oriented concepts. Most 3GLs support structured programming. A programming language such as C, FORTRAN,
or Pascal enables a programmer to write programs that are more or less independent from a particular
type of computer. Such languages are considered high-level because
they are closer to human languages and further from machine languages. In contrast, assembly languages are considered
low-level because they are very close to machine languages. The main advantage of high-level languages
over low-level languages is that they are easier to read, write, and maintain. Ultimately, programs written in a high-level
language must be translated into machine language by a compiler or interpreter. The first high-level programming languages
were designed in the 1950s. Examples of early high level languages are
ALGOL, COBOL, and FORTRAN. These programs could run on different machines
so they were machine-independent. As new, more abstract languages have been
developed, however, the concept of high and low level languages have become rather relative. Many of the early “high level” languages are
now considered relatively low level in comparison to languages such as Python, Ruby, and CommonLisp. See also
