INTRODUCTION TO C

Introduction to C

• An Overview of A C

• Similarities and distinctions between C and C++

• The benefits and drawbacks of utilizing C

• Commencing with the C

Dennis Ritchie of the Bell Labs created the general-purpose structural and procedural computer programming language C around 1972.

It is called the fundamental of the Programming language or a base of all kinds of programming languages.

It is closely related to UNIX because it was developed for the UNIX operating system along with other databases and applications.

Because it is one of the starting programming languages therefore if we learn it then we never have an understanding of other programming languages such as C++, JAVA, C#, and Python.

C, despite its advanced age, remains remarkably quick and versatile, finding potential applications in the development of device drivers, protocol stacks, and games. There are multiple versions available, including C89/C90, C99, C11, and C18. The ANSI C and ISO C standards were released in 1989 and 1990, respectively.

Examining C and C++

C++ is a more advanced version of C that was created by Bjarne Stroustrup after the development of C.

C++ and C are two programming languages that have unique features and qualities. C++ and C are two different programming languages with distinct characteristics. C++ is an object-oriented language that provides features such as classes and objects, while C is a procedural language.


C follows a different methodology compared to C++. While C takes a top-down approach, C++ utilizes a bottom-up strategy. C contains 32 keywords but C++ can contain 63 keywords.

C supports built-in data types but C++ contains both Built-in as well as user-defined data types.

C didn’t have an access modifier but C++ has.

C does not support reference variables but C++ does.

C has code in separate blocks known as functions but C++ code is divided into objects and class.

C is being used in MySQL, Windows Kernel, Oracle Database, Telegram Messenger, etc. and C++ is used in Google Chrome, Microsoft Office, 3-D games, etc.

 

Similarities between C and C++


C and C++ share a great deal of code in common.

They both have similar compilers and are constructed with the same syntax.

The file scope, heap, and stack variables have the same names in both.

Most of C++'s operators and keywords are also found in C.

 Advantages of C

1.       Effectiveness: C's speed and efficiency allow for the development of high-performance applications.

2.       Because C programs are OS- and cross-platform-neutral, they are incredibly portable.

3 C is considered optimal for systems programming and operating system development due to its ability to grant low-level access to system resources.
4. An abundance of information and resources are accessible to developers as a result of C's sizable and active user community.
5. C is extensively utilized, as demonstrated by the fact that numerous contemporary programming languages utilize it as their foundational language. 

Disadvantages:

 

1.  Because of its complex syntax and low-level access to system resources, C has a steep learning curve that complicates the learning process, particularly for newcomers.

2 Inadequate handling in C, which lacks automated memory management, can result in memory leakage and other complications associated with memory.
3 Object-oriented programming in C is more difficult to implement than in languages like Python or Java, primarily because of C's inadequate support for such programming paradigms.
4. In contrast to programming languages like Java or Go, C is less suitable for the development of multithreaded applications on account of its lack of inherent concurrency support.
5 When C applications are written without proper attention, they may have security risks, such as buffer overflows.

In summary, while C is an influential programming language that offers numerous benefits, it is not devoid of limitations, particularly for novice programmers or individuals engaged in intricate endeavors.
Beginning with the letter C

It is not possible to set English as the default language, as communicating with a computer necessitates the use of a language that it can comprehend.
Nevertheless, there is a notable resemblance in the manner in which English is learned: it commences with memorization of the alphabet, then progresses to the comprehension of letter combinations that constitute words, which subsequently constitute sentences, which constitute paragraphs, and so forth.
Constraints, variables, and keywords—essential building blocks of the C programming language—must also be comprehended before constructing an instruction in the language.


A group of instruction would be combined later on to form a program which is displayed above.
