C++ problem 11-2
In this chapter, the class dateType was designed to implement the date in a program, but the member function setDate and the constructor do not check whether the date is valid before storing the date in the member variables. Rewrite the definitions of the function setDate and the constructor so that the values for the month, day, and year are checked before storing the date into the member variables. Add a member function, isLeapYear, to check whether a year is a leap year. Moreover, write a test program to test your class.
Input should be format month day year with each separated by a space.

Code in C ++ that asks the user for an integer and that prints whether or not the number is divisible by three in the integers. If the number is not divisible by three, the program must write a message indicating what the remainder is obtained by dividing the number by three.

(Python) This is my code for printing a roster for a team. When I print to the console, it makes the first player's name show up as number 2, and it says [] (its just blank for 1). How can I fix that so the first player's name is 1, not skipping 1 and going to 2.
def file_to_dictionary(rosterFile):
myDictionary={}
myDict=[]
with open(rosterFile,'r') as f:
for line in f:
(num,first,last,position)=line.split()
myDictionary[num]= myDict
myDict=[first, last, position]
print (myDictionary)
return myDictionary

SNOWMOBILE CLUB - Database Development
Draw an Entity-Relationship Diagram which must include all entities and their attributes. Primary Keys underlined, Foreign Keys labeled, Weak entities double boxed.
You have been asked to develop a database to help the Wisconsin Snowmobile Association track their club members.
The following are the predefined business rules:
1) Snowmobile Clubs are tracked by Wisconsin county.
2) A club can be assigned to multiple counties.
3) Members can belong to one or more clubs.
4) Some clubs could have the same name.
5) New clubs can be started at any time.
6) The Wisconsin Snowmobile Association has an elected Executive Board consisting of a President, Vice President, Secretary, Treasurer and Executive Director, all of whom must be current members.
7) Each county must have a Director and a Representative.
8) Each club has a President, Vice-President, Secretary and Treasurer.

How does the use of dialogue in a storytelling game differ from its use in other forms of fiction?
|
A)The dialogue of characters in a game is always monotone but is characterized by the actor's voice and inflections in other forms of fiction. |
||
|
B)The dialogue in a storytelling game is always longer and more complex than in other forms of fiction. |
||
|
C)The dialogue of characters in a game can change based on the player's actions, whereas it stays the same in other forms of fiction. |
||
|
D)Only the protagonist and antagonist in a game can handle dialogue whereas any character in other forms of fiction can be given dialogue. |

JAVA
In this PoD you will use an ArrayList to store different pet names (there are no repeats in this list). This PoD can be done in your demo program (where your main method is) – you don’t have to create a separate class for today.
Details
Create an arraylist of Strings, then using a Scanner object you will first read in a number that will tell you how many pet names (one word) you will add to the arraylist.
Once you have added all the names, print the list.
Then read in one more pet name. If this is pet name already exists, do nothing, but if the pet name isn’t in the list, add it to the front of the list (e.g., the first position).
Print the list again.
Next read in two more pet names. If the first pet name is in the list, replace it with the second pet name. If the first pet name isn’t in the list, add the second pet name to the end of the list.
Print the list again.
Input
Example Input:
5 Whiskers Benji Lassie Smokey Bob Triffy Bob Max
Output
Example Output:
[Muffin, Benji, Snowball, Fluffy]
[Muffin, Benji, Snowball, Fluffy]
[Muffin, Benji, Snowball, Whiskers, Fluffy]

Have to use C language
Pseudocode
A #define called BITS should be set at the top of the program. It
should be set to 8 when the program is submitted. This
define should be used throughout the entire program when
setting/using array sizes/max element. This define will also
be used in the output to print 8-bit vs 16 bit. Your program should
function whether the define is set to 8 or to 16.
Part of the grading process will be to change the define from 8 to
16 and to recompile your program to see if your program still
runs properly. See sample output.
main()
Print instructions (see sample output below)
Prompt for and store both numbers and the operator. Use only one
scanf() to store all three values.
While either number is less than 0 or more than 255, continue to
prompt for input until a valid number is entered (hint
– use a while loop). See sample output below.
Call function ConvertDecimalToBinary() to convert the first number
to binary.
Call function ConvertDecimalToBinary() to convert the second number
to binary.
If the entered operator is an allowed operator, then convert the
result to binary and print the decimal result and
binary result as seen in the sample code.
ConvertDecimalToBinary()
Return type : void
Parameters :
int containing the decimal value to be converted
char array (hint : the array is passed empty from main() and this
function fills it so when the function
finishes, the array back in main() will contain the values added in
the function).
This function will use a method of decimal to binary conversion
called “Divide in Half, Ignore the Remainder”. Please
watch the following video for a demonstration of the method.
https://youtu.be/XdZqk8BXPwg
Create a local int array. This array will store the result of each
divide by 2 which will be accomplished using
bitshifting instead of division to divide the number in half. Use a
bitmask to determine if an array element if odd (1) or
even (0). YOU MUST USE THIS METHOD IN THIS ASSIGNMENT.
Using a for loop, loop over the int array and write each element
into the char array that was passed in. Hint : keep
in mind what the ASCII value is for the number zero when writing
the int array element into the char array. If you
store the number 65 in a char, it will be ‘A’ so if you want to
store the number 0 in a char array, you will need to …?
HINT : make sure your char arrays are one bigger than the number of
BITS so that you have room for the null terminator so
that %s prints correctly.
