C, C++

As a middle-level language, C combines benefits of both low machine level languages and high-level developer friendly languages. Further, it is fast, structured, portable and has a rich library. These features make C a general purpose programming language, and hence, it finds application across every domain in programming world.

A super set of C, C++ is an object-oriented programming language and incorporates all the features offered by C. C++ started its journey as C with classes. Gradually, it has evolved and despite the popularity of other programming languages like C# and Java, C, C++ holds its own as one of the most widely used languages for scripting.

It is the only industrial programming language that is built around this concept. In C++, life times of all objects are exactly known, and (well-written) C++ programs guarantee that resources are acquired and released in fully deterministic manner.

In comparison, garbage-collected or otherwise managed languages do not provide any such guarantees; in fact objects in those languages may persist after the end of their lifetime.That is the reason why C++ is used in finance, video games, high-performance embedded and real-time systems, transportation, manufacture, and other industries where determinism and precision are important.
