C Language
History:
Dennis Ritchie developed the C language at Bell Laboratories in early 1970. C was originally developed for writing code for the Unix operating system, which at the time used assembly programs that communicated directly with the computer’s hardware. Assembly programs can be complex and lengthy, and programmers need a language that supported a user-friendly instruction set. The C language met these goals and also helped overcome the problems programmers encountered with BASIC, B, and the Basic Combined Programming Language.
Due to its popularity and flexible features, it was soon released for cross-platform use and quickly became commercialized. C is still commonly used in web development projects, and many popular languages, such as Java, PHP, and JavaScript have direct or indirect syntax from C.
Although C has transformed over the years, it is still commonly used in lower-level programs such as kernels.
What Is C Language?
A program written in C must be run through a C compiler to convert it into an executable file that a computer can run. Many versions of Unix-based operating systems (OS) are written in C and have been standardized as part of the Portable Operating System Interface (POSIX).
Today, the C programming language runs on various hardware platforms and operating systems, such as Microsoft and Linux.
The C language comes with special features that make it one of the most used languages.
Some main advantages of C Language:
Dynamic memory allocation.
C supports a dynamic memory allocation feature that can be used at any time to free the allocated memory by calling the free() function.
Expandable.
A C program can be easily extended. If the code is already written, new features and functions can be added to it with minor modifications.
Indicators.
C uses pointers that improve performance by allowing direct interaction with system memory.
Intermediate-level programming language.
An intermediate language that supports both low-level and high-level features.
Portable.
C is machine-independent and C programs can run on different machines.
Recursion.
C allows developers to go back by providing code reusability for each function.
Rich library.
It offers numerous built-in library functions that speed up the development process.
Speed.
It is a compiler-based language that makes compiling and executing code faster. C contains only basic and required functions, it saves computing power and increases speed.
Structured.
It offers a structured programming approach to break down problems into smaller modules or functions that are easy to understand and modify.
Some disadvantages of using C Language:
Constructor and destructor.
C Language is not object-oriented, it does not offer constructor and destructor functions. Constructing or destroying a variable in C must be done manually using a function or other means.
Exception handling.
lacks exception handling, that is, handling exceptions such as errors and anomalies that may occur during source code.
Features of PPE.
C does not extend its support for object-oriented programming (OOP) features, allowing subclasses to be created from superclasses. Unlike Java, Python, or C++, you cannot create multiple inheritances in C, which makes it difficult to reuse existing code.
Garbage removal.
C is not equipped with waste collection. This important feature automatically reclaims memory from objects that are no longer needed by the library or application.
Namespace function.
C lacks namespace functionality, which means that the same variable name cannot be reused in the same scope. Without namespaces, it is not possible to declare two variables with the same name.
Runtime check.
does not display code errors after each line of code; instead, all errors are presented by the compiler after the program is written. This can make code review a problem, especially for larger programs.
Use of C language?
It has a wide range of real-world applications that are not limited to operating systems and application development. C is also used for graphical user interface development (GID) and integrated development environments (IDE).

Fibonacci Series
This code generates a Fibonacci series by calculating the next number in the series as the sum of the two previous numbers.
Factorial of A Number
This code calculates the factorial of a number provided by the user by iterating through a for loop and continuously multiplying the running factorial value by the loop variable i.
Sum of All Integers Divisible By 2 Between Two Numbers
This C program calculates the sum of all integers between two user-defined numbers (num1 and num2) that are divisible by 2 (i.e., even numbers).
Given Number is Palindrome Or Not
This code takes an integer input, reverses the digits of that input, and checks if the reversed number is the same as the original input.
Reverse of a Given Number
This code takes an integer input, reverses the order of its digits using a while loop, and then displays both the original and reversed numbers.
Sum of All Digits in a Number
This code takes a positive integer input, extracts each digit, calculates the sum of these digits, and then displays the original number and the sum.
Sum of N Numbers
This code takes a user-defined number ‘n’, calculates the sum of all natural numbers from 0 to ‘n’, and then prints the result.
Find Largest of Three Numbers
This code takes three numbers as input and finds and displays the largest number among them. It demonstrates the use of conditional statements in C for decision-making based on user input.
Arrange Zeros (0) to Right and Ones Left Side in Array
This C program takes user input to create an array of binary digits, checks the input for validity, sorts the array in descending order using the Bubble Sort algorithm, and then displays the sorted array.
