Introduction

History of C

  • C was invented and first implemented by Dennis Ritchie on DEC PDP11
  • that used the UNIX
  • operating system.
  • C is the result of a development process that started with an older language called BCPL.
  • BCPL was developed by Martin Richards, and it influenced a language called B, which was
  • invented by Ken Thompson.
  • B led to development of C in the 1970.
  • To alter this situation, ANSI established a committee in the beginning of 1983 to create a
  • standard for C, which was implemented in 1987.

ASCII Code

  • ASCII is an acronym for the American Standard Code for Information Interchange.
  • ASCII is a code for representing English characters as numbers, with each letter assigned a
  • number from 0 to 127.
  • For example, the ASCII code for uppercase M is 77.
  • Most computers use ASCII codes to represent text, which makes it possible to transfer data from
  • one computer to another.
  • Text files stored in ASCII format are sometimes called ASCII files.
  • Text editors and word processors are usually capable of storing data in ASCII format, although
  • ASCII format is not always the default storage format.
  • Most data files, particularly if they contain numeric data, are not stored in ASCII format.
  • Executable programs are never stored in ASCII format.
  • The standard ASCII character set uses just 7 bits for each character.
  • There are several larger character sets that use 8 bits, which gives them 128 additional
  • characters.
  • The extra characters are used to represent nonEnglish
  • characters, graphics symbols, and
  • mathematical symbols.

Programs

Write a program to input number of days from user and display it, week and days format.


For Example

input is : 20 days

then output is:

2 week and 6 days.
