What is a computer?

 

A computer is an electronic device which accepts data as input, performs operations on the data based on the instructions stored in the memory and produces output. General representation of a computer is as shown below:

 

computer-components

 

A computer is made up of two components: 1) Hardware and 2) software. 

The computer hardware is the physical equipment which is made of electronic components like registers, transistors, capacitors etc.. 

The software is the collection of programs that allow the hardware to serve its purpose. The purpose of the software is to use the underlying hardware components.

Constants in C

Image
  Constants in C Constants are fixed values, which do not change during the execution of a program. C supports several types of constants, which are as shown below:     Contents  [ hide ] 1  Integer Constants 2  Real Constants 3  Single Character Constants 4  String Literals or String Constants 5  Escape Sequences Integer Constants   An integer constant refers to a sequence of digits. Generally in programs, the number systems used are: decimal, octal and hexadecimal. Decimal integers consists of umbers from 0 to 9, preceded by an optional + or – sign.   Some valid examples of decimal integer constants are: 133, +45, -15, 0, 342332 etc. Embedded spaces and non-digit characters are cannot be used between digits.   An octal integer consists of numbers from 0 to 7. Octal integer numbers are always preceded by a zero. For example if we have to represent 35 in octal system, we must write it as 035 in the program. Some valid examples of octal integer constants are: 035, 02, 0435, +025 etc.

INTRODUCTION TO C

What is C?       C is a structured mid-level programming language for developing software. C follows structured programming in which the instructions are arranged or structured using blocks and functions. C is used for developing operating systems which are system software and also used to create application software. Hence, C is known as middle level language.          https://youtu.be/M_ZC-EIx-No Why C? (Advantages of C)       C is a powerful language using which we can develop operating systems, games and other application software. The advantages or characteristics of C language are:       1) Powerful and Flexible:  C is a flexible programming language. Using the concepts in C, a programmer can develop software for almost any kind of purpose. Various concepts like pointers, function, structures in C make it a powerful language.       2) Popular:  C has wide spread popularity in the programming league as it is very easy to learn, easy to write programs and easy to understand th

  C Tokens Contents   [ hide ] 1  Introduction 2  Character Set 3  C Tokens 3.1  Keywords 3.2  Identifiers Introduction   A programming language is designed to help process certain kinds of data consisting of numbers, characters and strings and to provide useful output known as information.   The task of processing data is achieved by writing instructions. These set of instructions is known as a program. Programs are written using words and symbols according to the rigid rules of the programming language known as syntax.     Character Set   The characters that can be used to form words, numbers and expressions depend upon the computer on which the program is run. The characters in C, are grouped into the following four categories: 1) Letters 2) Digits 3) Special Characters 4) Whitespaces   The compiler ignores the white spaces unless they are part of the string constants. White spaces are used to separate words from each other, but they cannot be used in between the characters of keywo
