CS150  Assignment  3   Daycare  Invoice  Calculator  

  Date  assigned:  Friday,  October  2,  2015   Part  1  due:  Tuesday,  October  13,  2015,  9:15am  (25  points)   Part  2  due:  Monday,  October  19,  2015,  1pm  (25  points)     You  have  been  asked  by  a  daycare  provider  to  write  a  program  to  create  monthly  invoices   for  customers.     Your  program  is  to  ask  the  user  for  the  month,  the  year,  and  the  cost  per  day.  You  will  then   output  a  monthly  invoice  showing  the  date,  day  of  the  month,  charge  for  that  day,  and  a   running  sum.  After  the  table  you  are  to  display  the  total  cost  for  that  month.     Below  are  some  sample  output  screens  using  various  input  values:

    Some things to note:  

1. The  daycare  only  charges  for  weekdays.   2. Assume  that  the  user  enters  only  valid  numbers  for  the  month,  year,  and  daily  cost.   3. Use  setw  to  format  the  table  as  shown  in  the  sample  output.   4. All  monetary  amounts  must  be  displayed  to  2  decimal  places.   5. There  must  be  no  magic  constants  in  your  program.

Determining  if  a  year  is  a  leap  year   You  must  determine  if  the  year  is  a  leap  year  so  that  you  can  provide  a  correct  invoice  for   the  month  of  February.  A  year  is  a  leap  year  if  it  is  divisible  by  4.  The  only  exception  to  this   is  if  it  is  a  century  year.  Then  it  is  a  leap  year  only  if  it  is  divisible  by  400.     Determining  the  day  of  the  week  of  a  particular  date:   To  calculate  the  day  on  which  a  particular  date  falls,  the  following  algorithm  must  be  used:  

a  =  (14  -­‐  month)  /  12  

y  =  year  -­‐  a  

m  =  month  +  12  *  a  -­‐  2   dayOfWeek  =  (day  +  y  +  y/4  -­‐  y/100  +  y/400  +  (31*m)/12)  %  7  

where  year  is  the  four-­‐digit  year,  month  is  the  integer  between  1  and  12,  day  is  the  day  of   the  month,  and  dayOfWeek  is  the  day  of  the  week.  The  value  for  dayOfWeek  is  0  for  Sunday,   1  for  Monday,  2  for  Tuesday,  etc.  All  variables  must  be  integers!  

For  example,  if  you  were  trying  to  find  the  day  of  the  week  on  which  9/1/2014  falls,  then   you  would  substitute:  

• 9  for  month   • 1  for  day   • 2014  for  year  

  The  result  in  dayOfWeek  will  be  1,  which  is  a  Monday.  

Part  1  (Due  10/13):  Name  the  project  (03_A_DaycareCalculator)  

For  part  1,  you  must  turn  in  a  program  that  displays  if  a  year  is  a  leap  year  or  not,  the   number  of  days  in  the  entered  month,  and  the  day  of  the  week  that  the  month  starts  on  in   that  particular  year.

Part  2  (Due  10/19):  Name  the  project  (03_B_DaycareCalculator)  

Submit  the  complete  program  as  described  on  page  1.  

To  complete  this  assignment  you  must  submit  the  following:     1. An  electronic  copy  of  your  program  on  grace  

a. Add  new  projects  named  03_A_DaycareCalculator  and  03_B_DaycareCalculator  to   your   previously   created   assignment   solution   called   PUNetIDAssignments.   It   is   vital  that  you  name  your  project  correctly!  

b. Type   your   program   (fully   documented/commented)   into   the   project.     The   comment  block  at  the  top  of  the  program  needs  to  contain  your  name,  the  date   the  assignment  is  due,  the  class  name,  assignment  number  and  name,  and  a  brief   description  of  the  program.  

c. Pay  attention  to  the  example  output!  Your  program’s  output  must  look  exactly   like  the  example  output!  The  spacing  and  newlines  in  your  output  must  match   exactly.  

d. Your   program   must   use   if   statements,   logical   operators,   constants,   switch   statements,  and  a  while  loop.  

e. Make  sure  that  your  program  compiles  and  runs  correctly.  If  you  get  any  errors   (or  warnings),  double  check  that  you  typed  everything  correctly.  Be  aware  that   C++  is  case-­‐sensitive.  

f. Once  you  are  sure  that   the  program  works  correctly   it   is   time  to  submit  your   program.  You  do  this  by  logging  on  to  grace  and  placing  your  complete  solution   folder   in   the   CS150-­‐01   Drop   folder.   This   solution   folder   must   contain   four   projects:   01_Fraction,   02_BankFees,   03_A_DaycareCalculator,   and   03_B_DaycareCalculator.  

g. The   program   must   be   in   the   drop   folder   by   1pm   on   the   day   that   it   is   due.   Anything  submitted  after  that  will  be  considered  late.  

2. A  hard  copy  of  your  program     a. The  hard  copy  must  be  placed  on  the  instructor’s  desk  by  1pm  on  the  day  that  it  

is  due.  

b. The  hard  copy  must  be  printed  in  color,  double-­‐sided,  and  stapled  in  the  upper-­‐ left  corner  if  necessary.  I  do  not  bring  a  stapler  to  class.  

  Good  luck!  And  remember,  if  you  have  any  problems,  come  and  see  straight  away.       The  printers  in  Marsh  are  slow.  Do  NOT  expect  to  be  able  to  print  your  code  10   minutes  before  class!
