C++ Language, its uses and applications

C++ is an object-oriented programming (OOP) language recognized by many as the ideal language for constructing large-scale applications. Programming languages considered object-oriented include C++, Eiffel, Lisp, Prolog, Simula, and Smalltalk. C++ is a completely object-oriented programming language compatible with C. Classes and objects developed as design entities may be implemented directly using C++ language techniques.

  • A considerable training effort.
  • Confusing designs by amateurs attempting to incorporate multiple inheritances.
  • Long debugging sessions.

Implementing object-oriented programming features involves complex development tools for compilation, linking, and debugging. In this we study many projects like library management system project in c++ with output.  This is primarily due to the implementation of inheritance and function overloading. Applications employing existing C code and libraries have varied programming styles and paradigms.

Uses of C++ in daily life

C++ (or “C-plus-plus”) is a general-purpose programming and coding language. C++ is utilized in building browsers, operating systems, and apps, as well as in-game programming, software engineering, data structures, etc. In this we also perform hotel management system project in c++. After understanding C++, let’s look at some intriguing domains where C++ is commonly employed. Here are some uses of C++ in daily life:


The compilers of several computer languages utilize C and C++ as the backend programming language. This is due to the fact that both C and C++ are comparatively lower-level languages and are closer to the hardware and hence are the optimal option for such compilation systems.

The rendering engines of different web browsers are write in C++ merely because of its speed. The rendering engines demand quicker execution to ensure that consumers don’t have to wait for the material to appear on the screen. As a consequence, such low-latency systems utilize C++ as the programming language.


Many high-level libraries utilize C++ as the fundamental programming language. For instance, numerous Machine Learning packages employ C++ in the backend because of its speed. Tensorflow, one of the most frequently used Machine Learning libraries, utilizes C++ as the backend programming language.

Operating Systems

Be it Microsoft Windows or Mac OSX, or Linux – all of them are develop in C++. C++ is the backbone of all the well-known operating systems because it is a highly typed and fast programming language, making it an excellent option for designing an operating system.


All graphics applications demand quick rendering, and much as the case of web browsers, here, too, C++ aids in reducing the latency. Software that utilizes computer vision, digital image processing, and high-end graphics processing requires C++ as the backend programming language.

Banking Applications

One of the most frequently used core-banking systems – Infosys Finacle, employs C++ as one of the backend development languages. Banking applications perform millions of transactions daily and need high concurrency and low latency support. C++ immediately becomes the favored option in such applications due to its speed and multithreading support that is made accessible via numerous Standard Template Libraries that come as a part of the C++ development kit.

Cloud/Distributed Systems

Cloud storage systems employ scalable file systems that function close to the hardware. C++ becomes a favored option in such cases since it is near the hardware, and also, the multithreading libraries in C++ enable high concurrency and load tolerance which is very much required in such scenarios.


Postgres and MySQL – two of the most frequently used databases are create in C++ and C, the forerunner to C++. These databases are utilize in practically all of the well-known programs we all use daily – Quora, YouTube, etc.

Advantages of C++ Over Other Languages

1. Object-Oriented

C++ is an object-oriented programming language which implies that the primary emphasis is on objects and operations around these things. This makes it simpler to alter code, unlike procedural or structured programming, which needs a sequence of computational procedures to be carry out.

2. Speed

When speed is an important parameter, C++ is the most desired alternative. The compilation and execution time of a C++ application is substantially quicker than other general-purpose programming languages.

3. Compiled

Unlike other programming languages where no compilation is necessary, all C++ code must first be convert to a low-level language and then run.

4. Rich Library Support

The C++ Standard Template Library (STL) includes several methods accessible to develop code rapidly. For example, there are STLs for containers like hash tables, maps, sets, etc.

5. Pointer Support

C++ also allows pointers which are sometimes not accessible in other programming languages.

6. Closer to Hardware

C++ is closer to hardware than other general-purpose programming languages. This makes it highly helpful in those areas where hardware and software are intimately connect and low-level assistance is require at the software level.
