Programming principle | Computer Science homework help

In this  assignment,  you will  be analyzing sequence,  selection,  and loop,  the relational comparison operators,  precedence when combining AND  and OR  operators,  and the case structure. Instructions: Part I. 1. 2. 3. 4. 5. Design a program  in which,  from  a date  entered by  keyboard with the format DAY,  MONTH,  YEAR,  the date of  the following day  is  obtained. Write a program  that  asks  the user  to enter  two numbers.  If  the first  number entered is  greater  than the second number,  the program  must  print  the message “The first  number  is  the  largest”,  otherwise the  program  must  print  the message “The first  number  is  the  smallest”.  Consider  the case that  both numbers  are equal  and print  the  corresponding message. Write a program  that  simulates  the normal  operation of  a modern elevator  with 25 floors  (levels)  and that  has  two buttons:  UP  and DOWN,  except  on the lower floor  (level),  that  there  is  only  a call  button to  UP  and the  last  floor  (level)  that only  exists  DOWN  button. Write a program  that  selects  the arithmetic  operation to be executed between two numbers  depending on the value of  a variable called selectionOp. Write an algorithm  that  displays  the next  double message: Enter  a month (1 for  January,  2 for  February,….…) Enter  a day  of  the month 

The algorithm  accepts  and stores  a number  in the “month”  variable  in response to the  first  question and accepts  and stores  a number  in the “day”  variable in response to the second question.  If  the  month entered is  not  between 1 and 12 inclusive,  an information message should be displayed  to  the user  warning that the number  entered is  not  valid as  a month;  in the same  way  we proceed with the number  that  represents  the day  of  the month if  it  is  not  in the range between 1 and 31.   Modify  the  algorithm  to alert  the  user  to no  enter  numbers  with decimals. Part II. 1.  In the  following pseudocode,  what  percentage raise will  an employee in Department  8 receive? if  department  <  5  then   raise =  SMALL_RAISE else    endif if  department  <  14  then raise  =  MEDIUM_RAISE else    endif if  department  <  9  then raise  =  BIG_RAISE endif 2.  Design a flowchart  or  pseudocode for  a program  that  accepts  two numbers from  a  user  and displays  one of  the following messages:  First  is  larger, second  is  larger,  numbers  are equal. 3.  Cecilia’s  Boutique wants  several  lists  of  salesperson data.  Design a flowchart or  pseudocode for  the  following: a.  A program  that  accepts  one salesperson’s  ID  number,  number  of items  sold in the last  month,  and total  value of  the items  and displays data message only  if  the salesperson is  a high performer—defined as a person who sells  more than 200 items  in the month. 

b.  A program  that  accepts  the salesperson’s  data and displays  a message only  if  the salesperson is  a high performer—defined a person who sells  more than 200 items  worth  at  least  $1,000 in the month. 4.  The Dash  Cell  Phone  Company  charges  customers  a  basic  rate of  $5 per month to send text  messages.  Additional  rates  are as  follows: •  The first  100 messages  per  month,  regardless  of  message length,  are included in  the basic  bill. •  An additional  three cents  are charged for  each text  message after  the 100th message,  up to and including 300 messages. •  An additional  two cents  are charged for  each text  message after  the 300th message. •  Federal,  state,  and local  taxes  add a total  of  14 percent  to  each bill. Design a flowchart  or  pseudocode for  the following: a.  A program  that  accepts  the following data about  one customer’s messages:  area code (three digits),  phone number  (seven digits),  and number  of  text  messages  sent.  Display  all  the data,  including the monthend bill  both before and after  taxes  are added. b.  A program  that  continuously  accepts  data about  text  messages  until  a sentinel  value is  entered,  and displays  all  the details c.  A program  that  continuously  accepts  data about  text  messages  until  a sentinel  value is  entered and displays  details  only  about  customers  who send more  than 100 text  messages. d.  A program  that  continuously  accepts  data about  text  messages  until  a sentinel  value is  entered and  displays  details  only  about  customers  whose total  bill  with taxes  is  over  $10.  A  program  that  prompts  the user  for  a three-digit  area code from  which to select  bills.  Then the program continuously  accepts  text  message data until  a sentinel  value is  entered and  displays  data only  for  messages  sent  from  the specified area code. 5.  Black  Dot  Printing is  attempting  to organize  carpools  to save energy.  Each input  record contains  an employee’s  name and town of  residence.  Ten percent  of  the company’s  employees  live in  Wonder  Lake;  30 percent  live in the adjacent  town of  Woodstock.  Black  Dot  wants  to encourage employees who live in either  town to drive to  work  together.  Design  a flowchart  or pseudocode for  the following: 

a.  A program  that  accepts  an employee’s  data and  displays  it  with  a message that  indicates  whether  the employee is  a candidate for  the carpool  (because he lives  in one of  the  two cities). b.  A program  that  continuously  accepts  employee data until  a sentinel  value is  entered and displays  a list  of  all  employees  who are carpool  candidates. Make sure  the decision-making process  is  as  efficient  as  possible. c.  A program  that  continuously  accepts  employee data until  a sentinel  value is  entered and displays  a list  of  all  employees  who are ineligible to carpool because they  do not  live in either  Wonder  Lake or  Woodstock.  Make sure the decision-making process  is  as  efficient  as  possible. Requirements: •  Show your  work  in a Word  document. o  Include all  your  work  for  each question. o  You can include screenshots  of  work  done on paper. •  For all  justification exercises,  remember  to use the definitions  and principles  that we have learned thus  far. •  You must  prepare a written work  where you respond to the programming exercises.  The work  must  comply  with APA  academic  writing standards.  You must  support  your  answer  using appropriate  sources  that  are properly  cited.    •  Minimum  four  pages  in length,  excluding the Title and Reference page. •  APA format,  including an in-text  citation for  referenced works. •  At least  three  resources.
