资源说明：C# programming assignments
This repo contains my assignments for my C# programming class. Below are the
assignment prompts.
Prompts:
Assignment String Input Output Summary: Grabbing a string from the user,
printing a string, and the system time. Print your name. Print the current
date and time (as it is at run time.) Ask the user for their name. Print "Hello
{username}, I'm {yourname}. It is nice to meet you." Example execution: Glenn
Cuevas 9/1/2010 2:33 PM What is your name? Jimmy Hello Jimmy, I'm Glenn. It is
nice to meet you.
Assignment Loops and Randoms Summary: Decisions and iteration, random numbers.
Create a coin flipping game. Ask the user if they want to play the game. If
they respond postively, then ask them to guess heads or tails. If they correctly
guess the coin flip indicate that they won the game and then ask them if they
want to play again. The game will continue until the user responds that they do
not wish to continue playing. Keep track of each time the player guesses
correctly or incorrectly and display their wins and losses. Also note that the
user input is not case sensitive. Example Execution: Wins: 0 Loses: 0 Do you
want to play? y Guess H for heads, T for tails: t The coin landed heads, you
lose. Wins: 0 Loses: 1 Do you want to play? y Guess H for heads, T for tails: T
The coin landed tails, you win. Wins: 1 Loses: 1 Do you want to play? n
Goodbye.
Assignment Variables Summary: Arithmatic, variables and arrays. Ask the user
for 10 numbers (which might be floating point.) Find the average value, the
median value and the sum. Print the numbers entered back to the user, followed
by the average, median and sum. The average is the sum divided by the count of
the numbers, the median is the value that occurs in the middle, since we have 10
numbers, that will be the 5th number. Example Execution: Enter number 1: 22.1
Enter number 2: 4 Enter number 3: 41 Enter number 4: 14 Enter number 5: 24.2
Enter number 6: 19 Enter number 7: 25 Enter number 8: 46 Enter number 9: 79
Enter number 10: 9 You entered 22.1, 4, 41, 14, 24.2, 19, 25, 46, 79, 9. The
average is 28.33. The median is 22.1. The sum is 283.3.
Assignment Loops Summary: Loops for factorials.
Write a program that finds the factorial for a given sequence of integers. Ask
the user for the starting value, then ask the user for the ending value.
Starting at the first number entered, display the factorial calculation and the
result of the calculation on a line. Do this for each value from the first
number to the last number entered. The factorial of a number n is = n * (n-1) *
(n-2) * (n-3) ... * 1. Where the factorial of 0 is equal to 1. IE 5! = 5*4*3*2*1
= 120
Sample Execution:
Welcome to the factorial calculator Enter the lower bound: 4 Enter the upper
bound: 7
Calculating... 4! = 4 * 3 * 2 * 1 = 24 5! = 5 * 4 * 3 * 2 * 1 = 120 6! = 6 * 5
* 4 * 3 * 2 * 1 = 720 7! = 7 * 6 * 5 * 4 * 3 * 2 * 1 = 5040
Goodbye.
Assignment Methods Summary: Methods, overloading, optional parameters. Write a
program that will analyze text. Write a function that will take a string
parameter with "Hello" as the default value for the optional parameter, this
function will count the number of words in the string. Assume that a word is
identified by a single space character. The return is the count of words.
Overload the above function by allowing it to take an array of strings. (There
must be two seperate functions.) Write a function that will count the number of
vowels in a string. The return is the count of vowels, case-insensitive. Create
a menu system similar to the sample output. When at the bottom of each menu
level, continue to perform the same operation until the user inputs the escape
sequence. i.e. -1 Example run: Main Menu Choose from the following: 1. Word
counting. 2. Vowel counting. 3. Exit Enter your selection: 1
Word Counter Menu Choose from the following: 1. Count the words in one sentence.
2. Count the words in a paragraph. 3. Parent menu Enter your selection: 1 Enter
a sentence (q to quit): Hello world, how are you today? There are 6 words in
that sentence. Enter a sentence (q to quit): I'm bored today. There are 3
words in that sentence. Enter a sentence (q to quit): q Word Counter Menu
Choose from the following: 1. Count the words in one sentence. 2. Count the
words in a paragraph. 3. Parent menu Enter your selection: 2 Enter several
sentences, when done entering sentences, use q by itself on the last line.
Hello, how are you? I'm fine, and you? Just fine, just fine. q There are 12
words in that text. Enter several sentences, when done entering sentences, use
q by itself on the last line. q Word Counter Menu Choose from the following: 1.
Count the words in one sentence. 2. Count the words in a paragraph. 3. Parent
menu Enter your selection: 3 Main Menu Choose from the following: 1. Word
counting. 2. Vowel counting. 3. Exit Enter your selection: 2 Vowel Counting
Menu Choose from the following: 1. Count vowels. 2. Parent menu. Enter your
selection: 1 Please enter some text to count the vowels (q to quit). Hello Abe,
what are you up to today? There are 13 vowels. Please enter some text to count
the vowels (q to quit). q Vowel Counting Menu Choose from the following: 1.
Count vowels. 2. Parent menu. Enter your selection: 2 Main Menu Choose from
the following: 1. Word counting. 2. Vowel counting. 3. Exit Enter your
selection: 3 Goodbye.
Assignment Forms Summary: Forms
Create a calculator, using calc, as available in windows, as the model. The
calculator needs to support the following mathmatical operations. Addition
Subtraction Multiplication Division Modulo (Remainder) Square Root
The interface needs to also support Clear (C) and Clear Entry (CE) buttons, the
clear button restores the text back to zero. The clear entry will clear the
current entry and retain the previous calculated value.
The text box should be formatted with the thousands comma separator, ie:
123,456,789.2
The calculation scenarios supported are entering a sequnce of numbers (through
the buttons, or typing), then choosing an operator, then another sequence of
numbers, followed by the equal sign, or another operator, when this occurs, the
result of the previous operation is evaluated. I.E. the user enters 1, hits the
+, then 2, then +, the text would be updated to 3, then 3, then *, where it will
be come 6, then they enter 5 and hit equals, resulting in 30.
Assignment Forms and Classes Attached Files: User Registration Screen
Shot.gif (10.289 KB) Summary: Forms and Classes, Enumerations
Create a user registration system.
It will need to contain the fields as shown in the screen shot. The password
and confirm password fields need to be matched against each other, both when the
page is submitted and also when the confirm password field has lost focus, also,
when the password field has lost focus. If the form is not valid then the page
will not be processed as described below.
The major is a combo box (DropDownList style) that will contain a list of majors
(at least 5) of your choosing. Based upon the major selected you'll populate the
items in the specialty drop down list below the major, for the user to select
from those items.
Once the form is succesfully submitted we'll use the values in the form to
create a user object.
The user object will be composed of private data members plus properties, all
the fields will be strings, with the exception of the major, which will be an
enumeration.
The clear button will reset the form to its initial empty state. The load last
button will repopulate the form with the last user object that was created, if
no user object has been created, show a MessageBox with an error message
indicating there is no data to load.
Dice Rolling Attached Files: Dice Rolling.PNG (47.006 KB) Summary: Dice
Rolling, Forms, Menus, AI
This is a two player game, each player takes turns rolling a single six sided
die. If the roll is a 1, the players turn is over and the turn passes. If the
roll is 2 - 6, the player addes the value of the die to the turn total. After
adding the die to the turn total, the player can then choose to roll again, or
take the turn total and add it to their game score. If they roll again, repeat
the check above, ending the turn on a 1 (no scoring), or adding the points
otherwise, if they take the points, play passes to the next player.
A rough mock-up is attached and shows about what the game would look like.
The game needs to support a menu with the following options. Exit - Closes the
form. New Game - Resets the game to the beginning.
A players menu with Set player 1 name, set player 2 name, and set number of
players. The number of players can be 1 or 2.
In a two player game, to human players will play against each other. In a one
player game, the AI will play for the second player, the behavior of the AI is
to roll until their turn ends on a 1, or their turn total is 20 or more.
When the AI is playing, the game needs to pause for a couple of seconds between
roles so that the human player can see what is happening.
The game ends at 100, when the game ends, show a message box that indicates the
player that won.
Assignment Tic Tac Toe Summary: Tic Tac Toe - Form
Create a two player tic tac toe game. The game requires a menu allowing for the
game to: exit for the game to be reset to change which player goes first which
player is X or O setting of the player's names.
When the game is over, show a message box indicating the winner. Following that,
show a prompt box asking if they want to play again, if they play again use the
following to determine who goes first.
When a player wins, they get to go first again on the second game by default. If
the first player loses, the second player goes first on the next game, if the
game is a draw, then switch who went first on the second game.
Blackjack Summary: Blackjack
Create a black jack application that is designed to help the player learn the
odds of playing the game.
The game will allow the user to specify how many decks of cards will be used.
The game needs to support all the actions that a game of black jack allows for,
such as doubling down, splitting, hitting, standing.
The basic idea for the player is to get as close to 21 points as possible
without exceeding 21 points, and have a higher number of points than the dealer.
The cards are A 2 through 10, Jack, Queen and King. 2 - 10 are worth 2 - 10
points respectively, Jack, Queen and King are worth 10 points. Ace can be used
as either 1 or 11 points.
A black jack is having two cards, one of which is an Ace, the other a 10 point
value card. A black jack is an automatic win for the player, unless the dealer
also has a black jack. In this scenario, the player wins 1.5 times their bet.
Hitting causes the player/dealer to get another card. Standing indicates the
player/dealer will not take any more cards this hand. Splitting is the action
of creating two hands from a single hand when the first two cars of the hand are
the same face value, ie two eights, or two jacks, but not a ten and a queen.
Doubling down is the act of doubling the player's bet after they have received
their first two cards, in this scenario, the player only gets to hit one time,
allowing them 3 total cards.
The player loses when their hand's point value exceeds 21, they also lose if
after they finish taking cards, the dealer has more points than the player, not
to exceed 21. If both the dealer and player have the same number of points, the
hand is a draw. When the dealer is taking cards, they hit until they have 17 or
points. The dealer will hit on a soft 17, where they are using an Ace as 11
points.
For showing the odds, based upon the current point value of the player's hand,
what the chances are of the player busting if they draw a card. For example, if
the player has a 7 and an 8, and the dealer is showing a 10, then any card with
a value larger than 7 will cause the player to lose. We'll assume the deck is
full, with the exception of the shown cards, so normally there are 16 cards at
10 points, 4 each at 9, 8, and 7. For a total of 28 cards and 52 cards in the
deck, that would give the player a 53.8% chance of busting, with a 7, 8 and 10
gone, that changes it to 25/49, down to a 51.0% chance of busting.
Optional: Show the odds of the dealer busting. Use a counting system to track
cards used and how that changes the odds.
Tic Tac Toe w/ AI Summary: AI
Add an AI to the tic tac toe game, which brings in the ability to play with one
human player. The AI will support several difficulty levels.
Each level builds on top of the previous levels, thus, if the added behavior
does not apply, then they would choose randomly. Level 1 - AI will randomly
choose their next move. Level 2 - AI will block the player if their next move
would win the game. Level 3 - AI will recognize a winning move and will try to
win the game. Level 4 - AI places higher value on corner and center spots, only
taking sides to win/block. Level 5 - AI is impossible to beat.
When developing the AI, it is good to recognize that there are many mirror
cases, for example, choosing any of the 4 corner spots for the first move are
identical. When this is the case, to make the games appear to be different, it
is good to randomize which of these moves gets used in subsequent games.
