IF YOU HAVEN'T GO THROUGH PREVIOUS PROGRAMMING BLOGS:




C – Language History


  • C language is a structure oriented programming language, was developed at Bell Laboratories in 1972 by Dennis Ritchie
  • C language features were derived from earlier language called “B” (Basic Combined Programming Language – BCPL)
  • C language was invented for implementing UNIX operating system
  • In 1978, Dennis Ritchie and Brian Kernighan published the first edition “The C Programming Language” and commonly known as K&R C
  • In 1983, the American National Standards Institute (ANSI) established a committee to provide a modern, comprehensive definition of C. The resulting definition, the ANSI standard, or “ANSI C”, was completed late 1988.


C standards


  • C89/C90 standard – First standardized specification for C language was developed by American National Standards Institute in 1989. C89 and
  • C90 standards refer to the same programming language.
  • C99 standard – Next revision was published in 1999 that introduced new futures like advanced data types and other changes.ICP




Features of C language:


  • Reliability
  • Portability
  • Flexibility
  • Interactivity
  • Modularity
  • Efficiency and Effectiveness




Uses of C language:


C language is used for developing system applications that forms major portion of operating systems such as Windows, UNIX and Linux. Below are some examples of C being used

  • Database systems
  • Graphics packages
  • Word processors
  • Spread sheets
  • Operating system development

In put The first line of the input contains a single integer T  denoting the number of test cases. The description of T  test cases follows. The first line of each test case contains two space-separated integers  N  and X . N  lines follow. For each valid i , the  i -th of these lines contains two space-separated integers  S i  and  R i . Output For each test case, print a single line containing one integer - the highest rating of an IMDB movie which Chef can store in his hard disk. Cons traints 1 ≤ T ≤ 10 1 ≤ N ≤ 5 ⋅ 10 4 1 ≤ X ≤ 10 9 1 ≤ S i , ...

  ATM Problem Code:  HS08TEST Pooja would like to withdraw  X  $US from an ATM. The cash machine will only accept the transaction if  X  is a multiple of 5, and Pooja's account balance has enough cash to perform the withdrawal transaction (including bank charges). For each successful withdrawal the bank charges 0.50 $US. Calculate Pooja's account balance after an attempted transaction. Input Positive integer 0 <  X  <= 2000 - the amount of cash which Pooja wishes to withdraw. Nonnegative number 0<=  Y  <= 2000 with two digits of precision - Pooja's initial account balance. Output Output the account balance after the attempted transaction, given as a number with two digits of precision. If there is not enough money in the account to complete the transaction, output the current bank balance. Example - Successful Transaction Input: 30 120.00 Output: 89.50 Example - Incorrect Withdrawal Amount (not multiple of 5) Input: 42 12...

Compare the Triplet | HackerRank | Solution in C

-
  Compare the Triplet Alice and Bob each created one problem for HackerRank. A reviewer rates the two challenges, awarding points on a scale from  1  to  100  for three categories:  problem clarity ,  originality , and  difficulty . The rating for Alice's challenge is the triplet  a = (a[0], a[1], a[2]) , and the rating for Bob's challenge is the triplet  b = (b[0], b[1], b[2]) . The task is to find their  comparison points  by comparing  a[0]  with  b[0] ,  a[1]  with  b[1] , and  a[2]  with  b[2] . If  a[i] > b[i] , then Alice is awarded  1  point. If  a[i] < b[i] , then Bob is awarded  1  point. If  a[i] = b[i] , then neither person receives a point. Comparison points is the total points a person earned. Given  a  and  b , determine their respective comparison points. Example a = [1, 2, 3] b = [3, 2, 1] For elements *0*, Bob ...
