What is C++?

In the 1980s, Bjarne Stroustrup created this amazing high-level programming language, ” C++.” It was created as an extension of the C programming language to offer extra capabilities like object-oriented programming and templates. Operating systems, gaming engines, device drivers, and other types of software are frequently developed using C++. The creation of web browsers and other programs also uses it.

C++ for Data Science

This general-purpose language may be used to develop effective and high-performing programs. For Data Science applications that call for processing massive volumes of data, this makes it a strong fit.

The usage of C++ also facilitates the creation of algorithms and libraries for use in data science. Several libraries have also been created in C++, especially for data science, like the Dlib library, a machine-learning library for classification, regression, and clustering. The renowned Fast Fourier Transform (FFT) technique and other algorithms for numerical analysis may be created using C++.

For example, C++’s support for templates may be used to create general algorithms that can operate on a variety of data types. This is just one of many properties that make C++ helpful for data science. C++’s robust support for parallel programming made analyzing a huge amount of data quicker and more efficient.

Advantages of using C++ in Data Science

  • Speed and Efficiency

C++ is one of the fastest programming languages of all time. It is renowned for being very performant, which makes it perfect for applications that call for quickness and effectiveness. When working with vast volumes of data, data scientists must do intricate computations and analyses. Data scientists can handle and analyze massive data sets more quickly using C++ than they can with many other computer languages. C++ is a wonderful option for applications that analyze big data sets because it is very efficient concerning memory use.

  • Object-Oriented Programming

C++ is considered to be an excellent choice for any developer as it is built on the OOPs concept. As OOP provided, writing and organizing code is much simpler. It also aids in the production of reusable code. C++ is considered the best choice for any data science project as it makes it easy for developers to make complicated applications.

  • Multiple platforms support 

As a platform-independent language, C++ may be used with several operating systems. This makes it a wonderful option for data scientists who work with several platforms since they can build code that can be utilized across them without requiring major adjustments. Web browsers, operating systems, and game creation are just a few of the applications that employ C++.

  • Libraries and Frameworks

For data science, C++ provides a large selection of libraries and frameworks. These frameworks and libraries make it simpler for data scientists to create complicated applications without having to develop original code. Armadillo, Eigen, and OpenCV are a few of the widely used frameworks and libraries in C++ data science applications. Matrix operations, linear algebra, and image processing are just some of the features offered by these libraries.

Integration with Other Languages

C++ has the ability to get combined with many other languages like Python, R, etc. The best of both worlds is offered by being able to use C++ libraries and frameworks within Python or R programming. The popular data science languages Python and R are integrated with C++, enabling data scientists to benefit from C++’s speed and efficiency without having to change their existing codebases.

Disadvantages of using C++ in Data Science

  • Steep Learning Curve

As a sophisticated programming language, C++ takes much time and effort to master. It has a difficult learning curve, which intimidates newcomers. Writing efficient, optimized code may be difficult for data scientists who are not familiar with C++. But the advantages of adopting C++ in data research frequently exceed the steep learning curve.

  • Memory Management

Programming in C++ requires effective memory management, which can be difficult for novices. C++ may have some memory leaks and other memory-related problems as it requires manual memory allocation and deallocation in C++. It may be challenging for data scientists who are unfamiliar with memory management to create memory-efficient code.

  • Lack of Interactivity

Since C++ is not an interactive language, data scientists who demand an interactive environment should not use it. Data scientists need interactive platforms because they enable them to experiment with data and models in real-time. C++ is less suited for interactive data science jobs because it is primarily intended for batch processing. 


To sum up, C++ is a strong programming language with several applications in various industries, including data science. Even though it might not be the most widely used language for data science, many experts in the area nevertheless use it. C++ is considered to be an excellent choice for some data science applications as it has various benefits over other languages, including high performance, efficiency, and the ability to work with a low-level data structure. 

Various C++ libraries and frameworks, including Boost, Armadillo, and Eigen, will always help perform data science. These libraries include functions and classes that are particularly created for scientific computing and for applications like linear algebra, optimization, and numerical analysis.

Apart from being the toughest language to master, professional programmers still consider it if they want to advance their careers. Anyone can learn C++ and utilize its special features and advantages in data science if they put in the time and effort.

Besides everything, learning any language is subject to the need, passion, and decision of any data scientist. Although it may not be the most widely used language for data science, C++ is still a useful resource that may be utilized to resolve complicated issues and improve efficiency.


Q: Does C++ make an excellent data science programming language?

A: C++ can be a functional programming language for data science as it performs well and can work well with simple data structures.

However, it is quite a difficult learning curve when compared to other programming languages like Python or R.
