What Is the Best Way to Learn C++?

C++ is a general-purpose programming language used for everything from game development to databases and IoT devices. Its flexibility and popularity in modern professional fields make learning C++ an avenue to numerous career opportunities in computer science. To determine the best learning path for you, explore what C++ is, compare different learning options, and identify potential careers that use skills in this area. 

What is C++?

C++, pronounced “C plus plus,” is a programming language used to write instructions that computers can understand to perform specific tasks. You can think of it as a detailed set of instructions directing your computer on what actions to take. C++, developed as an enhanced version of C, incorporates object-oriented programming features into the traditional development environment. Object-oriented programming allows you to organize your instructions more clearly in your code, enabling the creation of reusable “objects” that represent real-world entities such as files, bank accounts, and game characters.

Because C++ is known for its performance, efficiency, and control over memory management, it’s an excellent choice for developing system software, desktop applications, and video games. C++ also offers a standard library (sometimes referred to as the Standard Template Library or STL), which includes a collection of common data structures and algorithms. This library allows you to take shortcuts during coding to perform more advanced tasks. For instance, you can quickly store and organize your data sets using built-in sorting algorithms like the sort() function, or you can implement multithreading, which enables you to run multiple tasks simultaneously. 

How to learn C++

You can take several effective approaches to learn this programming language. The best way to learn C++ depends on your learning style, goals, availability, and timeline. Your career goals may influence your choice, whether you’re seeking an entry-level position or simply wanting to learn a new skill for your current job. Your specific circumstances will determine the best option for you. When making your decision, consider the following options. 

Choose a boot camp

Coding boot camps provide targeted training programs focused on the practical skills needed to implement C++ in your personal or professional life. These boot camps typically last from two to four months, depending on the course structure and whether you are enrolled full- or part-time. 

Boot camps are generally more affordable than traditional degree programs and are designed for working professionals who want to switch careers or maintain relevance in their field. Many boot camps also offer opportunities to complete projects or exercises that you can add to your portfolio, showcasing your proficiency in specific areas.

Take an online course 

Online courses are another great way to learn C++ quickly and effectively. They typically offer a flexible, affordable, and self-paced learning environment, allowing you to code outside your day-to-day responsibilities. You can use these courses to grasp the basics or explore a new area before committing to more resource-intensive learning options. 

On learning platforms like Coursera, you can enroll in individual courses, usually lasting one to four weeks, or pursue Specializations, which consist of a series of courses over a few months. Beginners can start with targeted courses, such as C++ Basics: Selection and Iteration by Codio, or opt for more general Specializations like Programming in C++: A Hands-on Introduction by Codio. As you advance, consider taking intermediate courses like Object-Oriented Data Structures in C++ from the University of Illinois Urbana-Champaign, which is part of the intermediate Accelerated Computer Science Fundamentals Specialization.

Work on personal projects

Another effective way to learn C++ is through the practical application of the concepts you learn. This approach reinforces your knowledge and fosters a deeper understanding of the topics. You can begin by finding sample code online and then copying and pasting it into your compiler. This allows you to see how each segment functions and provides a foundation for experimenting with different variations. 

Once you understand the basic workings of C++, you can take advantage of several free online project platforms, such as Code with C, to explore simple programming projects. These projects vary in topic and complexity, enabling you to explore different areas and gradually progress to more advanced techniques and applications. 

Join communities 

As you continue your learning journey, online communities can help you learn from fellow coders and improve your own skills. You can avoid the mistakes others have made, try tips to improve your code’s efficiency, and receive advice on the best way to learn or apply new concepts. You can find C++-specific communities on DEV, cplusplus, Reddit, All About Circuits, and more.

Will earning a computer science degree make you proficient in C++?

While earning a degree in computer science or a related field doesn’t guarantee proficiency in C++, it can provide you with the tools necessary to enter a career in computer programming, including roles that use C++. An undergraduate degree program will guide you through both theoretical and practical concepts, such as problem analysis, assessing the legal and ethical implications of coding, and designing and developing innovative software programs. Graduate degrees, on the other hand, are typically more specialized, allowing you to explore specific applications or areas within the computing field. 

If you’re interested in learning C++ specifically, it’s important to evaluate the course offerings of potential degree programs. Look for programs that include specific courses in C++ or that allow students the flexibility to choose their programming language. Many colleges and universities offer introductory C++ courses, and some provide advanced C++ courses or certificate programs focused solely on this language. 

Careers with C++

As you begin your journey with C++, you may wonder what career opportunities this skill can unlock. C++ is a versatile language, enabling you to explore various professional pathways, from general programming to specialization in specific fields or segments of the development process. Three main categories of career pathways you can pursue include the following:

Computer programmers

Median annual salary: $98,670 [1]

Computer programmers design, implement, maintain, and troubleshoot computer software and applications. This profession is widely regarded as one of the best technology jobs, and salaries are significantly above the national average [1]. 

Software developers, quality assurance analysts, and testers

Median annual salary: $131,450 [2] 

Professionals in this field design and test computer applications. Their responsibilities include identifying project risks, employing both manual and automated testing methods, reporting system functions and issues, and evaluating current software to ensure the best results for users.

Web developers and digital designers

Median annual salary: $95,380 [3]

As a web developer or designer, you create and maintain websites and interfaces to facilitate user access and navigation. This role involves writing code, creating and testing applications, ensuring graphics and layouts align with your vision, and monitoring website traffic. 

Learn C++ with Coursera

You can learn C++ through various methods, ranging from structured and comprehensive degree programs to targeted bootcamps and online courses. On Coursera, you can explore several learning options. Consider the BSc in Computer Science from the University of London for a comprehensive choice. This coursework helps you learn to use a range of programming languages, including Python and C++, and allows you to focus on IT career specializations, such as data science, web and mobile development, or machine learning and AI.
