Many widely used languages that came after C, such as C#, PHP, Java, LPC, JavaScript, and Unix’s Shell, are directly or indirectly influenced by C. Syntactical has been the deepest influence in which all the languages mentioned above come along with , more or less recognizably, the C expression syntax and statement. On the other hand, data models, type systems, and/or large-scale program structures are different, sometimes radically, from those of C. It remains one of the most influential languages in the world, especially in the realm of embedded systems.
C++ and Objective C:
With the popularity of object-oriented languages, it was C++ and Objective C that were the two different extensions of C and the ones that provided goal-oriented efficiencies. Both languages were initially implemented as source-to-source compilers, meaning the source code was translated into C and then compiled with a C compiler.
C++:
To make object-oriented functionality available with a C-like syntax, Bjarne Stroustrup elaborated on the C++ programming language as an approach, as C++ includes superior scope, force typing, and other tools that are useful in object-oriented programming and allows generic programming through templates. Almost a superset of C, C++ now includes most of C, albeit with a few exceptions.
Target C:
Originally, Objective C was a fairly thin layer on top of C that allows object-oriented programming by means of static or dynamic hybrid prototyping. It is still a strong superset of C. In addition to C, from which Objective C inherits the syntax covering preprocessing, expressions, function declarations, and function calls, Objective C originally borrowed the syntax for object-oriented functions from Smalltalk.
D:
The D language, which, unlike C++, which maintains almost all backwards compatibility with C, makes a clean split with C while retaining the same broad-spectrum syntax. What D does is have a number of C features, such as the C preprocessor and trigraphs, that D’s designer, Walter Bright, considered unnecessary. However, not all but some of the extensions from D to C have something in common with those from C++.
Piton:
One of the most important examples of a scripting language that has its origins deep in C is Python. Although Python’s syntax is not the same as C’s, it is written in C. Additionally, the fact that Python is an open source program allows programmers to extend Python with C or integrate it into programs written in C. It is because of its close connection to C that Python enjoys its success as a general-purpose programming language.
Pearl:
Another example is from Perl. Perl differs from Python in that its syntax closely follows C syntax. Furthermore, Perl is not only written in C, but works quite well with programs that have C extensions.
