Programming in "C"

 Introduction 

 C is a general-purpose programming language that was developed in the early 1970s by Dennis Ritchie at Bell Laboratories. It has since become one of the most widely used programming languages and has influenced the development of many other languages, including C++, Java, and C#. C is known for its efficiency, flexibility, and low-level programming capabilities. It is commonly used for system programming, embedded systems, and developing operating systems. C is also a popular choice for developing applications that require high performance, such as game engines and scientific simulations. 

 Here are some key features and concepts of C programming:
  •   Syntax: C has a relatively simple syntax compared to some other programming languages. It uses a combination of keywords, variables, data types, operators, and control structures to write programs.
  •  Variables and Data Types: You declare variables to store data in C. Various data types are available, including integers, floating-point numbers, characters, and more. You can also define your own data types using structures and unions.
  • Functions: C allows you to define functions to perform specific tasks. Functions help in organizing code and making it more modular. They can be reusable and can accept parameters and return values.
  • Control Structures: C provides control structures such as if-else statements, loops (like for and while), and switch statements to control the flow of execution in a program.
  • Pointers: Pointers are a powerful feature of C. They allow you to manipulate memory directly and work with addresses of variables and data structures. Pointers enable efficient memory management and the ability to work with complex data structures.
  • Arrays and Strings: C supports arrays, which are collections of elements of the same type. Arrays are useful for storing and manipulating multiple values. C also treats strings as arrays of characters and provides functions to manipulate them.
  • Input and Output: C provides functions for input and output operations. Using standard library functions, you can read input from the keyboard and write output to the screen or files.
  • Preprocessor Directives: C has a preprocessor that processes the source code before compilation. Preprocessor directives, denoted by the '#' symbol, allow you to include header files, define constants, and perform other preprocessing tasks. 
 To start programming in C

we would typically write our code in a text editor and save it with a .c extension. We would then compile the code using a C compiler, which translates the code into machine-readable instructions. The compiled code can be executed to produce the desired output. Many C compilers, such as GCC (GNU Compiler Collection), Clang, and Microsoft Visual C++, are available. We can choose a compiler based on our operating system and personal preference. Learning C can provide a strong foundation for understanding programming concepts and open up various software development and system programming opportunities.

ARITHMETIC OPERATIONS ON BINARY NUMBER

Binary arithmetic is simpler to learn because binary number system deals with only two digits - 0 and 1. Binary number perform all arithmetic operation such as Addition, Substraction, Multiplication and compliment as in decimal number system. Binary Addition The addition table for binary arithmetic consist of only the following four entries: 0+0=0 0+1=1 1+0=1 1+1=0 , plus a carry of 1 to the next column.     1011        + 1100    10111     1100    + 1100     11000 Binary Substraction There are three ways to do substraction between binary numbers:- 1. Simple Substraction 2. Substraction using 1's Complement 3. Substraction using 2's Complement Simple Substraction: The complete table of binary substraction is as follows: 0-0=0 0-1=1, borrow 1 from next column 1-0=1 1-1=0    1101 - 0101   1000     1001   - 0111    0...

Media Of Communication Part 2

Unguided Media Unguided media transport electromagnetic wave without using a physical connection. This type of communication referred as wireless communication. We can divided wireless transmission in :-   1. Radio Wave:- Electromagnetic   waves ranging in frequencies between 3KHz and 1GHz are normally called radio wave.   On radio wave connectivity used communication used Bluetooth, Wi-Fi, etc.     Bluetooth :- It is a wireless network connectivity that enables to connect or transfer data between devices over a short range the physical range of connection up to 100 meter. Ex- Mobile phone, barcode scanning, portable speaker, wireless keyboard, mouse etc.      Wi-Fi (Wireless Fidelity):- Wi-Fi is a network of wireless connection. Wi-Fi network establish by radio frequency like Bluetooth, but has more power, resulting a strong connection.    ·   Wi-Fi is also called wireless Ethernet. It has connectivity range up...

BASIC STRUCTURE OF A COMPUTER SYSTEM

Computer Function A computer performs action and accomplishes its task in three basic stages namely:- INPUT – Input is the data that is fed into the computer by the user. PROCESS – Processing refers to the series of action by which the computer converts raw data into information. OUTPUT – Output is the result which is termed as information. Input Unit Data and instructions enter a computer through an input unit in a form that depends upon the input device used. Ex- Keyboard, Mouse, Joystick, Scanner etc. CENTRAL PROCESSING UNIT (C.P.U) CPU is also known as the brain of the “Brain of Computer”. As it appears as a hardware component, but it is also a functional component of a computer system. Functional Elements of a CPU        1.        Arithmetic Logic Unit(ALU)        2.        Control Unit(C.U)        3.    ...
