This historic programming language will be half a century old in 2022.<\/span><\/p>\n<blockquote>\n<p style=\"text-align: center;\"><span style=\"font-weight: 400;\">Thus, it was in 1972 that the American computer scientist Dennis Ritchie created the C programming language.<\/span><\/p>\n<\/blockquote>\n<p><span style=\"font-weight: 400;\">It was originally designed as <\/span><b>an improvement of language B<\/b><span style=\"font-weight: 400;\">. That's where it even got its name. The C programming language was used to create the Unix operating system, making it possible to implement the popular PDP-11 minicomputers.<\/span><\/p>\n<p><b>C code is characterised by its efficiency<\/b><span style=\"font-weight: 400;\">It is therefore one of the most widely used languages for designing system software.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">C programming language: definition<\/span><\/h2>\n<p><b>The C programming language is considered to be one of the most important programming languages today.<\/b><span style=\"font-weight: 400;\"> Its flexibility gives the computer programmer a great deal of freedom; however, it has a low level of error checking, so that the responsibility of the professional is total.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In addition to the development of operating systems, <\/span><b>C is key in the creation of apps<\/b><span style=\"font-weight: 400;\"> and supports more modern languages such as Java, C++ or C#.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">On the other hand, C is composed of a base in which the different functions are stored in the form of code blocks and thus operate on the marked parameters.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">C language features<\/span><\/h2>\n<p><b>What are the main features of the C programming language?<\/b><span style=\"font-weight: 400;\"> Below are the properties of C:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Structured programming:<\/b><span style=\"font-weight: 400;\"> C is a structured language.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>It is not hardware dependent:<\/b><span style=\"font-weight: 400;\"> In this way, it is possible to migrate to different operating systems.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Category:<\/b><span style=\"font-weight: 400;\"> It is a medium-level programming language.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Multitasking:<\/b><span style=\"font-weight: 400;\"> In this sense, it does not have a specific task, so it can be used to program everything from operating systems to apps, from spreadsheets to videogames.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Flexibility:<\/b><span style=\"font-weight: 400;\"> As we have already mentioned, this will provide absolute freedom for the computer programmer.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Rapid development:<\/b><span style=\"font-weight: 400;\"> Fast programme creation and high capacity.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Composition:<\/b><span style=\"font-weight: 400;\"> Although the number of keywords is small, the C programming language is rich in data types, operators and variables.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>A processing language:<\/b><span style=\"font-weight: 400;\"> The C preprocessor is used to define the macros in order to include different source code files.<\/span><\/li>\n<\/ul>\n<h2><span style=\"font-weight: 400;\">C syntax<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">In order to know what C is, it is important to note that this programming language is the 'father' of later programming languages such as PHP, Objective-C or JavaScript, among others. This means that <\/span><b>C syntax is similar to the above.<\/b><\/p>\n<p><b>Syntax is the format in which different computer programs are created.<\/b><span style=\"font-weight: 400;\"> In particular, the C syntax has different rules and processes that drive the structure of a program.<\/span><\/p>\n<blockquote>\n<p style=\"text-align: center;\"><span style=\"font-weight: 400;\">It should be noted that the C programming language is case-sensitive, so it is programmed in lower case letters.<\/span><\/p>\n<\/blockquote>\n<p><span style=\"font-weight: 400;\">In addition, <\/span><b>the minimum unit of the C programming language is the token<\/b><span style=\"font-weight: 400;\">. Tokens are small blocks of code that can be variables, constants, keywords, identifiers... in short, symbols that comprise C or sentences of this programming language.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">On the other hand, like the <\/span><a href=\"https:\/\/immune.institute\/en\/librerias-python-que-son\/\"><span style=\"font-weight: 400;\">Python libraries<\/span><\/a><span style=\"font-weight: 400;\">Among the most outstanding libraries of this programming language, we can mention several examples such as <\/span><b>stdio.h, conio.h or time.h<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Why C programming: Advantages of this programming language?<\/span><\/h2>\n<p><b>The C programming language is very efficient <\/b><span style=\"font-weight: 400;\">and offers the possibility to handle all aspects of CPU instructions.
