The C programming language was created by Dennis Ritchie. It was designed to allow programmers to write programs that could run on any computer system with few changes. C++ was created by Bjarne Stroustrup, who added the ability to use C for object-oriented programming. C++ also introduced additional functionality into the language, such as templates, function overloading, and exceptions.

What's the Difference Between C vs. C++?

Since C++ is an evolution of C, the two languages have a lot in common. However, when looking at C vs. C++, C++ adds functionality for object-oriented programming. It also adds references, namespaces, type safety, and variable declarations in conditionals. These additional characteristics differentiate C++ from C.

Another difference between C and C++ is that C is a procedural language that takes a top-down approach, and C++ is an object-oriented programming language that takes a bottom-up approach. A procedural language calls procedures that contain a series of steps and runs them. Object-oriented programming uses data and objects in addition to logic and functions.

Top-down programming starts with a high-level description of what the program should do and breaks those tasks into smaller pieces that correspond to the simplest elements in the programming language. Bottom-up programming takes the opposite approach, starting with the simplest elements and building up to more complicated tasks.

Why Learn C and C++?

Although C and C++ are not among the easiest programming languages to learn, they are certainly worth the effort. Note that some programmers choose to learn how to program in C before taking on C++, since C is part of C++.

C is used for many purposes, including:

C++ is also used for many different applications, including:

Even though they have been around for years, C and C++ are still among the most popular programming languages. The TIOBE index for November 2021 lists C as the second most popular programming language and C++ as the fourth most popular language.

How Can I Learn C and C++?

If you want to know how to learn C or how to learn C++, you'll have many different options. These include books on C++ for beginners, courses on platforms such as Udemy and Coursera, coding bootcamps, and online degree programs. You'll need to evaluate your options and decide on the best way to learn C++.

Before You Get Started With C and C++

Before you start programming in C or C++, you must download a compiler. The compiler converts the code you write into a file that can be executed by a computer. Some popular compilers include Code::Blocks for Windows and g++ for Linux.

Decide How You Will Learn C and C++

If you are an independent learner, you can teach yourself C or C++ using a book, course, or even YouTube videos. Many online C and C++ courses are free or inexpensive, costing at the most a few hundred dollars. This is very cheap compared to the cost of a coding bootcamp or a college degree, but you will be on your own, with little or no support to help you learn.

Bootcamps for C and C++

If you need the help of an instructor to learn C or C++, a bootcamp might be a good choice. Most coding bootcamps take a few months to complete and teach you the basic skills you need to know to pursue an entry-level job in the field. The average cost of a bootcamp was $13,579 in 2020.

Computer Science or Computer Programming Degrees

The traditional route to a computer programming career involves earning a bachelor's degree in computer programming or computer science. Although this route takes much longer than a bootcamp, it provides a broader education that includes general education courses as well as a solid grounding in computer science principles. Check the required courses before choosing a program. Not all computer science or computer programming degrees cover C or C++.

Follow the Program

Most courses and programs follow a logical progression, teaching the basics first and adding more complex features as you learn. However, if you find that a particular program is not working for you, don't hesitate to try another method.

Cons of Learning C and C++

While there are many good reasons to learn C and C++, there are also downsides to programming in C or C++. Here are a few of them.

What Jobs Can I Get if I Know C and C++?

C++ programming is in high demand, especially for video game programming. As of November 2021, there were over 75,000 C++ programming jobs listed with Indeed, including the following:

Frequently Asked Questions About C and C++

How long does it take to learn C++? true

C++ is somewhat difficult to learn, especially if you have never programmed before or you have never used a low-level programming language before. If you are a beginner with no programming experience, you should expect it to take at least three months to learn the basics. If you have programmed before, it may only take you a month or two.

To build mastery in C++, you should expect to spend at least two years working on improving your skills a little each day.

What is C++ used for? true

C++ is often used for video game development. Video games are very complex and require a programming language that can keep up with everything that is going on. C++ is also used for GUI-based applications, banking applications, and operating systems.

Many programming libraries use C++ since they require high-level mathematical computations. C++ has the high speed and performance required for programming libraries. C++ is also widely used to manipulate hardware resources.

Can I learn C++ as a beginner?

Yes, you can learn C++ as a beginner, but it will take longer than if you already have a firm grasp of programming. If you have never programmed before, look for a C++ course that is designed with beginners in mind. Another option would be to try to learn an easier language first, then come back to C++ when you feel you are ready.

Is it better to learn C or C++ first?

Geeks for Geeks recommends learning C first because it allows you to get the basics down before you start learning the extra features that C++ provides. Some of the features in C++ offer shortcuts, or easier ways of doing things. This might sound great to a beginner, but if you don't learn how to do it without the shortcut, you won't have that technique available in your toolbox when you need it.
