What Is C Language ?

Even after the ANSI standard was published in 1989, for many years K&R C was still considered the “lowest common denominator” that C programmers restricted themselves to when they needed maximum portability, because many older compilers are still in use And because K&R was written with care. C can also be a legal standard for C. Many later languages ​​borrowed syntax/functions directly or indirectly from the C language.

Like Java syntax, PHP, JavaScript, and many other languages ​​are mostly C based. C ++ is almost a superset of C (some programs can compile in C, but not C ++). Descendants of C include Concurrent C, Objective C, C *, and the widely used C ++. The C programming language is used to develop system applications that make up most operating systems such as Windows, UNIX, and Linux.

The C language is a systems programming language because it can be used for low-level programming (such as drivers and kernels). It is a structured programming language that is machine independent and widely used to write various applications, operating systems such as Windows, and many other complex programs such as Oracle database, Git, Python interpreter, and others. It forms (or is the basis) of the core of modern Java and C ++ languages.

It is a very portable language, which means that programs written in C can be run on other machines. This function is required if we want to use or execute code on another computer. The compiler then translates the language into what the machine can use.

A procedural language divides a program into functions, data structures, and so on. In C, variables and function prototypes must be declared before they can be used.

There are many compilers on the market that can be used to run programs written in this language.

What Is C Language ?

Although C was developed as a programming language for the UNIX operating system, it now has many compilers and can be used on almost any hardware platform and operating system. Initially, C programming was limited to the UNIX operating system, but when it began to spread around the world, it became commercialized and many cross-platform compilers were released.

C has also become one of the most commonly used programming languages ​​for writing other system software and applications. C is still one of the most efficient general-purpose programming languages ​​and has been used to build many compilers, computer architectures, operating systems, video game engines, and even other programming languages. Many companies use C as their programming language for embedded system development, application and socket programming. The low-level coding and embedded programming that programmers love, C has gradually entered the semiconductor, hardware, and storage industries.

By learning C, you will be able to understand and visualize the inner workings of computer systems (such as memory allocation and management), their architecture, and the general concepts that guide programming. While many applications use different programming languages ​​other than C, most of these languages ​​were developed using C. So as you learn C, you may discover the opportunity to work on large open source projects, such as contributing to Python, which will impact to millions of programmers around the world.

If you are already familiar with some programming concepts and have already learned how to program in other languages, you may want to start with C ++. C ++ is much easier to understand if you already have a solid foundation in the C programming language; however, you can still learn C ++ as your first language if you want to jump straight into object-oriented programming. Although it lacks more advanced programming features such as object-oriented programming, C programming remains one of the most widely used general-purpose programming languages ​​in the world, with extensive applications in computer science and software development.

The low-level procedural C language is designed to run on multiple platforms and provides access to important functionality such as memory management. AC programming creates source code for many UNIX operating systems, compilers, video games, and even other programming languages ​​such as Python.

C is one of the most powerful “modern” programming languages ​​because it provides direct memory access and many “low-level” computer operations. C works like a compiled language, which means that it compiles and then converts programs into an easily readable object file.

A procedural language defines a series of steps a program must take to solve a problem. In short, a compiler is a program that takes source code as input and translates it into something closer to the native language of computers. The step we are now discussing is when, upon compilation, each instruction of the preprocessed C source code program is converted into a language more suitable for the computer.

A C program is a human readable form, while the executable file that exits the compiler is a machine readable and executable form.

This means that in order to write and run a C program, you need access to the C compiler. This means that after you have written your C program, you need to run it through the C compiler to turn the program into an executable file. what your computer can do (do).

Many source files can be compiled and linked together to form a program. The C language allows you to use simple and powerful syntax to organize your programs. This book goes beyond C grammar and teaches you style rules so that you can write easy-to-read and reliable programs. I hope this will give you an idea of ​​how and how the language works, and the basic knowledge needed to start writing basic C programs.

Many interesting projects, from large database servers or operating system kernels to small integrated applications that you can even build at home for personal satisfaction and pleasure, are done in C. There is no reason to stop doing what you might love. The only reason you don’t know an old and small, but strong and time-tested programming language like C.

C++ is a cross-platform language that can be used to build high-performance applications. C++ was developed by Bjarne Stroustrup as an extension of the C language. The C language was developed by Dennis Ritchie and used to create system applications that directly interact with hardware devices (such as drivers, kernels, etc.).

C is widely used for systems programming in the implementation of operating systems and embedded system applications [40], because C code written for portability can be used for most purposes, but when necessary to access certain hardware addresses and execute word games in accordance with external interface requirements with low runtime requirements for system resources

. C contains 32 keywords, various data types, and a set of powerful built-in functions that make programming very efficient. The main features of the C language include low-level memory access, a simple set of keywords, and clean styling. These features make the C language suitable for systems programming such as operating system or compiler development.\
