Importance of ‘C’ language C language is a famous programming language due to its qualities. Some qualities are: It is robust language whose rich setup of built in functions and operator can be used to write any complex program. Program written in C are efficient due to several variety of data types and powerful operators. The C compiler combines the capabilities of an assembly language with the feature of high level language. Therefore it is well suited for writing both system software and business package. There are only 32 keywords; several standard functions are available which can be used for developing program. C is portable language; this means that C programs written for one computer system can be run on another system, with little or no modification. C language is well suited for structured programming, this requires user to think of a problems in terms of function or modules or block. A collection of these modules make a program debugging and testing easier. C language has its ability to extend itself. A c program is basically a collection of functions that are supported by the C library. We can continuously add our own functions to the library with the availability of the large number of functions. In India and abroad mostly people use C programming language because it is easy to learn and understand. The reasons to use C for the following: C is one of the foundations for modern information technology (IT) and computer science (CS). Many working principles of IT and CS, such as programming languages, computer architectures, operating systems, network communication, database, graphical user interface (GUI), graphics, image processing, parallel processing, multi-threads, real-time systems, device drivers, data acquisition, algorithms, numerical analysis, and computer game, are based on or reflected in the functionalities and features of C. The experience in C will help students understand the working principles of these important concepts in IT and CS. Therefore, C is required for the CS major in almost all universities. C is the most commonly used programming language in industry. Academic institutions have a mission to teach technologies that are widely used in the real world so that students have the skills and knowledge that employers need. More than 90 percent of the programs running on our desktops, from operating systems and e-mail clients to Web browsers and word processors, are written in C or its relative, C++ which has extensions to C. Most games and underlying robot control software are written in C or C++. With the knowledge of C, students will not only be able to play games and robots, but also understand their underlying working principles and potentially develop their own games and robots. C is the language of choice for programming embedded and mechanization systems with hardware interfaces. C is one of the most commonly used programming languages in colleges and universities. Computer programming is an essential skill for advanced studies in Science, Technology, Engineering, and Mathematics (STEM) fields. Like in industry, C is also one of the most commonly used programming languages in colleges and universities for teaching and research. C is the base for almost all popular programming languages. C is the language of choice for system programming. Because of the performance and portability of C, almost all popular cross-platform programming languages and scripting languages, such as C++, Java, Python, Objective-C, Perl, Ruby, PHP, Lua, and Bash, are implemented in C and borrowed syntaxes and functions heavily from C. They share the similar operators, expressions, repetition statements, control structures, arrays, input and output, and functions. C excels as a model of programming languages. C does an excellent job of illustrating the underlying working principles of computers, scientific computing, and disciplined software development. Students gain valuable knowledge of such fundamental programming concepts as data types, internal data representations, operators, expressions, loops for repetitions, control structures, arrays, input and output, functions, debugging, etc. Studying C provides a solid foundation for students who want to learn advanced programming skills such as object-oriented programming, event-driven programming, multi-thread programming, real-time programming, embedded programming, network programming, parallel programming, other programming languages, and new and emerging computing paradigms such as grid-computing and cloud computing. Once students have learned C, they can pick up any other languages by themselves. Certain languages and tools are typically used to solve domain specific problems. Therefore, the ability to understand and learn new languages is important. All other modern languages borrowed heavily from C. Once students learned C, it is easy for them to learn by themselves any other computer languages without much difficulty. On the other hand, even if students have learned other programming languages or visual programming, it is generally still quite difficult for them to learn C by themselves, especially for difficult topics such as pointers and linked lists. Computer programming in C needs a disciplined approach. Many people believe that if students start with computer programming using a typeless scripting language first, then they would have even harder time to learn and master C afterwards. C is a standardized programming language with international standards. A standardized programming language is stable and its evolution is overseen by a technical standard committee made up of business, academic, and organizational representatives with a stake in the language. Computer programming is becoming a necessary skill for many professions. Writing computer programs is essential to solving complex science and engineering problems. Many principles and concepts in STEM disciplines can be illustrated and reinforced through writing programs. C and C++ are more widely used in STEM fields than any other programming languages such as Java, Fortran, or Matlab. Computer programming can develop student's critical thinking capabilities. Developing a program to solve a practical problem involves many creative works, including design, logic reasoning, math, etc. It can help students find practical applications of many math concepts such as variables in Algebra I and trigonometry. Debugging a program can also help student improve their reasoning and logical thinking capabilities. The computer-aided problem solving capabilities can be trained using C.
