 C is a widely used, straightforward, and adaptable general-purpose computer language. It is a machine-independent, structured programming language that is widely used to create a wide range of apps, operating systems like Windows, and many more sophisticated programs like the Git repository, the Oracle database, the Python interpreter, and more.
The programming language "C" is allegedly created by a deity. C might be considered the foundation of programming. Knowing C will make it simple for you to understand the concepts of other programming languages.
Because it is a crucial component when working with the C programming language, it is imperative to have a background in computer memory systems.
The benefit of "C" programming is that it can grow. A "C" program includes several functions that are found in a library. To the library, we may add our features and capabilities. These features are available to us at any moment in our software, and we may use them. By using this capability, working with complicated programming is made simple.
Several compilers on the market may be used to run programs created in this language. In this, we will also discuss[c projects for beginners](https://rrtutors.com/c/academic-projects.php) for their ease. 
Since C is a very portable language, applications created in it may execute on different computers. If we want to utilize or run the code on another machine, we need this functionality.
**Some basic syntax rules of c language:**
•	All C instructions must be written in lowercase letters since the language is case-sensitive.
•	A semicolon must conclude each C statement.
•	Blank spaces and tabs are referred to as whitespace in C.
•	There must be a whitespace between identifiers and keywords.

**C++ Language:**
	C++ is a version of the traditional C programming language augmented with object-oriented programming and other features. C++ is an “intermediate-level” language, meaning that it facilitates “high-level” programming—i.e., in the abstract—and “low-level” programming of actual hardware. This utility at both ends of the programming spectrum has made C++ useful for many systems requiring careful allocation of memory, such as Web browsers, search engines, video games, movie effects, financial tools, flight software, and space-exploration equipment. However, C++ is one of the more-challenging programming languages to apply on a large scale.
C++ grew in ubiquity among programmers. A year following its debut, around 2,000 programmers used C++, and that number more than quadrupled every year after that, reaching 50,000 by 1989, according to Stroustrup's estimations. When version 2.0 was released that year, it included crucial new capabilities like multiple inheritance and abstract ideas while also enhancing space efficiency and the language's general "safety" (i.e., putting safeguards against different mistakes). Borland, a producer of C++compilers, said in October 1991 that it had fulfilled 500,000 orders and that more than 60 additional English-language publications on C++ were in use.
**Difference between C++ & C language?**
•	C++ is an Object-Oriented Programming language, whereas C is a Procedural Oriented language.
•	While C++ allows both pointers and references, C only supports pointers.
•	The usage of function overloading is not permitted in C, however, it is permitted in C++.
•	While C++ supports both built-in and user-defined data types, C supports just built-in data types.
•	C++ uses a bottom-up programming method, whereas the C language uses a top-down one.
•	In C++, cin and cout are provided for standard input and output operations, whereas C scan and printf are used for standard input and output in C.
**Why do we use C language?**
C is the language of choice for laying a solid programming foundation:
You must understand a variety of principles in programming, including classes, objects, polymorphism, and inheritance. These ideas provide the foundation for more complex languages. You may find the foundation for these ideas in the language C.
 It is simple to understand:
The C programming language employs blocks to segregate sections of code carrying out various jobs, and it is straightforward to grasp. This keeps the code tidy and facilitates programming. As a result, even beginners may easily comprehend the code.
C is used in embedded programming:
 which is a language for controlling microcontrollers. Automation, computers, and robots all employ these microcontrollers. Knowing C will also be helpful.
**C++ and Java are built on its foundation:**
Among the most popular programming languages, today are Java and C++. Their grammar and ideas are derived from the C programming language. Learning C++ and Java will be simpler once you are familiar with the fundamentals of C programming.
**It moves quickly:**
When compared to programs written in other languages, those written in C compile and run far more quickly. This is due to the lack of rubbish pickup and other unnecessary processing costs.
**It is used to build pc games:**
C is a programming language that is used to create numerous PC games. It has also been used to code some of the jobs in larger games as well as several little games. Thus, if you want to work in the game development industry, understanding C might be helpful.
**Get the best of both worlds with it:**
Programming languages are divided into three levels: Low-level, Mid-level, and high-level. While high-level languages are more user- and developer-friendly, low-level languages process programs more quickly. The C language is a medium-level one.
**Library management project:**
A college library management project is one that electronically organizes and maintains book information following the demands of students. Like this we will also explain [hotel management system project in c++](https://rrtutors.com/tutorials/hotel-management-system-project-using-c-plus-plus).  The approach makes it easier for students and the librarian to keep track of all the books that are currently accessible in the library. It enables both the learner and the administrator to look up the appropriate book. A project for a library management system in C++ manages the library's records. It gives details about the number of books in the collection, how many were released, and how many were returned or renewed. Linked lists are used in the C programming language to build the library management system. The primary tasks entail lending out books, having them returned, and keeping track of the volumes that have been loaned out. There will also explain [library management system project in c++ with output](https://rrtutors.com/tutorials/library-management-system-project-in-cplusplus).
**Library management system project in C++:**
•	We first build the class "books" before declaring all of its internal functions and variables.
•	After that, we establish the function of books and ask the user to enter the book's name, author, publisher, price, and stock.
•	Then we declare the function body to show and print information such as book name, author, publisher, price, and stock current availability or present on the screen.
•	Then, we go to the main function where we define an array ob[10], an int ch for the switch case to generate user operations, and an int n for asking the user to save a certain number of books at a specific time.
•	The book's char bname[20] for the book's name and name [20] for the author's name are then searched in switch case 3.
•	Then, for both the book name and author name, we compare the searched name and stored book name using the strcmp() method.
•	We publish Book Present if the comparison is successful; else, we print Not Present.
•	We are utilizing a do-while loop for user selection.
