How to learn C language easily
C learn to program
C is a procedural and imperative programming language that has influenced many other popular languages such as PHP, Perl, and Java. The programming language was developed in 1972 by an American programmer named Dennis Ritchie. The name "C" is derived from the previous versions A and B. C is primarily used for programming applications and systems. The basic programs of all systems based on Unix, and many other operating system kernels, were programmed in C.

Why should I study C?
Solid basis, proven and versatile
Although C is one of the oldest programming languages, it is still one of the most popular programming languages today. If you want to learn programming, C is definitely recommended. Many newer languages are based on C. Thus, once you have mastered C, you can learn many other programming languages more easily and, above all, understand them better. Almost all hardware-related programming is done in C. The programming language is so popular because you benefit from enormous freedom when programming and are not restricted by any editors.
Programming languages based on C are for example:
- PHP for web development
- Perl for web and Linux development
- C ++ for software development
- C # for system and software development
- Java for software development
The C programming language is available to you on almost every computer system, because it has been standardized several times under C99, C11, C89 and C90: The main area of application of the programming language is in the creation of operating systems, in system programming and in the development of embedded systems.
Writing programs with C is possible with far less code compared to other programming languages. This makes execution faster and uses fewer resources. In addition, the written programs can easily be imported to other systems. C has a comparatively small range of languages. The smallest C compiler can compile itself and consists of just 3,742 bytes of code.
The programming language C is very well known and popular and has a wide range of applications. C programs can be easily ported between different systems. The programs do not require a special runtime environment or a special interpreter. You can create resource-saving and fast applications with the programming language. This is mainly due to the direct access to the hardware and the storage space.
C and C ++ are programming languages that have remained forever young and function as the basis for almost all low-level systems. Regardless of their age, the two programming languages always remain in demand and show promise. This works best if you are familiar with all of the programming languages' capabilities.
Extensive libraries and a huge community
The C programming language has a huge community. If you have a question or a problem, you will find a suitable answer or solution on the Internet in no time. Every problem you will encounter while learning or programming C has certainly already been solved by another programmer and has put an easy-to-understand solution on the Internet.
Good salary and job prospects
If you can program with C, it will certainly pay off well for you. Programmers in this field are urgently needed in many large cities, above all in Hamburg, Munich and Berlin. The Internet job platform StepStone specializes primarily in specialists and executives and had more than 50,000 open job offers for C programmers online in the summer of 2020 alone.
Employees who work as C programmers earn an average of an annual salary (according to a survey by Salary.de) of around 60,000 euros. The maximum possible income is over 72,000 euros, while the minimum income is around 52,000 euros. By far the highest salary for C developers in the USA. Up to $ 80,000 a year is common here.
Getting started with C programming is not that easy, especially due to the rather complex language. We definitely recommend one of the online courses or tutorials listed below if you want to learn C programming.
What can I program with C?
Basically, you can program almost anything with C, because it is a complete programming language. Regardless of whether you are writing a program, for example, which corresponds to the ANSI standard and which is then portable between Linux and Windows. Or whether you commit yourself to a certain platform (e.g. Microsoft Windows) and program specific things for this. Among other things, you can program Windows-specific programs with the well-known WinAPI or develop games using DirectX. Regardless of the area of application, the only question is how well the programming works in practice. For this reason there are many other programming languages besides C and each individual language has its strengths in a different area.
What do you need to program with C?
There are several integrated development environments (IDEs for short) for the well-known operating systems Windows, Mac OS and Ubuntu Linux and these provide you with everything you need as a budding C programmer:
- an editor with which you can write the program code
- a compiler with which you can translate your program code into a language that the respective system understands
- a debugger to help you troubleshoot
The best thing to do is to opt for a freely available IDE such as NetBeans, Eclipse or the easy-to-use and clear Code :: Blocks. All 3 development environments are available under Windows, Mac OS and Linux.
Alternatively, you can use a conventional text editor and simply work with a C compiler at the command line level. This partly makes it easier for you to use the external libraries and these provide you with additional functions. Most conventional text editors have what is known as syntax highlighting, and with this you can highlight the most important elements of C in color.
Differences between C and the C ++ programming language
- C supports structured programming with functions, structures and variables. The programming language processes procedures on the basis of specific instructions and is suitable for imperative programming.
- C ++ was developed from the C programming language in the early 1980s.
- Object-oriented programming is possible with C ++. You can describe relationships and interactions by translating real objects, their dependencies and their relationships to one another with the help of several abstract objects in C ++. In addition, C ++ provides you with templates for generating program codes and preprocessor macros and impresses with its higher performance.
- In contrast to C, with C ++ you can even use different file extensions in the header and in the source code. The header files simplify the handling of extensive applications for you. Several variables are agreed in the files and special source codes are stored that can be accessed by programs belonging together or by several program parts.
What should I start with? C or rather C ++?
The answer to this important question mainly depends on what you want to program later, what previous knowledge you already have and how much patience and time you want to invest in the respective project.
For a completely new entry into the world of programming, C is more recommended. The well-known programming language has fewer language elements and can therefore be learned more quickly. Once you have mastered C, you have already mastered a huge part of C ++ at the same time. If you want to program applications for a microcontroller or hardware-related programs, you only need the elements that the C programming language provides. In addition, almost every platform has its own C compiler.
If you want to learn C ++, you need more time and more patience. In return, you benefit from significantly more options and can also program larger applications. Should you later switch from C to C ++, you will benefit from the knowledge you already have. If you want to work in the opposite direction, you first have to find out what doesn't work with the C programming language. If you want to program an application for a processor in the future that only has a C compiler, this harbors numerous sources of error.

FAQ: The most common questions about C
Who invented the C programming language?
The imperative, procedural programming language was developed at the "Bell Laboratories" by computer scientist Dennis Ritchie at the beginning of the 1970s.
What is the difference between C, C # and C ++?
- C is useful for developing procedures that consist of a sequence of statements.
- C # is a collection that consists of several libraries (subroutines) and from these the program is put together. The calls to the individual functions do not exist in C #.
- C ++ is a consistent further development of the C programming language. This includes object-oriented programming and allows the development of more powerful applications.
