Data Representation in Computer

How Computers Represent Data

  • All symbols, pictures, or words must be reduced to a string of binary digits.
  • A binary digit is called a bit and represents either a 0 or a 1.
  • These are the only digits in the binary or base 2, number system used by computers.
  • A string of eight bits used to store one number or character in a computer system is called a byte.

One byte for character A 01000001

The computer representation in ASCII for the name Alice is

01000001 = A

01001100 = L

01001001 = I

01000011 = C

01000101 = E

  • To represent the numbers 0 through 9 and the letters a through z and A through Z, computer designers have created coding systems consisting of several hundred standard codes.
  • In one code, for instance, the binary number 01000001 stands for the letter A.
  • Two common coding systems are Extended Binary Coded Decimal Interchange Code (EBCDIC) and American Standard Code for Information Interchange (ASCII).
  • EBCDIC represents every number, alphabetic character, or special character with eight bits, used primarily in IBM and other mainframe computers.
  • ASCII was originally designed as a seven-bit code, but most computers use eight-bit versions.
  • ASCII is used in data transmission, PCs, and some larger computers.
  • The computers store a picture by creating a grid overlay of the picture.
  • Every single point in this grid or matrix is called a pixel (picture element) and consists of a number of bits.

Array in C Programming | C Programming

Array in C Array in C Programming The C language provides a capability that enables the user to define a set of ordered data items known as an array. Suppose we had a set of grades that we wished to read into the computer and suppose we wished to perform some operations on these grades, we will quickly realize that we cannot perform such an operation until each and every grade has been entered since it would be quite a tedious task to declare each and every student grade as a variable especially since there may be a very large number. In C we can define a variable called grade, which represents not a single value of grade but an entire set of grades. Each element of the set can then be referenced by means of a number called an index number or subscript. Declaration of arrays Like any other variable arrays must be declared before they are used. The general form of declaration is: type variable-name [50]; The type specifies the type of the elements that will be contained in the array,

C program to Find Cartesian Product of Two Sets | C programming

C program to find the Cartesian Product of two sets   Cartesian product  is a mathematical operation that returns a set (or  product set  or simply  product ) from multiple sets. That is, for sets  A  and  B , the Cartesian product  A  ×  B  is the set of all ordered pairs  ( a ,  b )  where  a  ∈  A  and  b  ∈  B . Products can be specified using set-builder notation, e.g. {\displaystyle A\times B=\{\,(a,b)\mid a\in A\ {\mbox{ and }}\ b\in B\,\}.}
