please help me with this code.You will implement an algorithm that represents a simplified, two-player version of
blackjack (also known as “21”). A dealer shuffles cards and distributes them. The goal of
the game is to get as close to 21 as possible without going over 21. If the dealer or player
goes over 21, then that hand loses. If neither player not dealer have scored 21, then the
hand with the higher score wins

M & N imports batteries from Japan. Each box that is imported has the following properties
How many dozen in the box
Manufacturer
Manufacture date
Name of batteries
Country of manufacture
Date of purchase
Dimension of the box in which the batteries are packed. The length, width and height of the box are the same
Cost price of a single box of batteries
The company hires containers of varying sizes based on how much they want to import. There are only three sizes/dimensions of containers to be hired. The container people levy a fee that is 1% the cost price of the box. Each type of battery occupies its own container. To maximize profit, the company makes sure it doesn’t transport batteries that are less half the container. If the boxes required are less, the order is cancelled. All batteries get into the country through Busia, a district that borders Kenya. Each and every box of batteries is levied a tax that is 10% the cost price. For Each box sold, the company would like to generate a profit of 20% the cost price. If one is buying, they can’t buy below 3 boxes. If the stock of batteries goes below a certain number, the system should notify the user of the system.
The company would like to implement an information system using C programming. Write a c program whose input may include the following but is not limited to that
1. Number of boxes to be imported.
2. Properties of the boxes to be put in the container as per the list above. (same in the same container)
3. The three dimensions of containers available for hire
4. How many boxes have been purchased
5. Number below which the system should request the company to purchase
Output can include the following but is not limited to that:
1. Which container is used for a given pack
2. How many boxes are available in stock
3. How much profit made assuming no other expenditures (apart from what has been indicated above)
4. How many boxes have been sold out
5. Which name of battery is selling the most
6. Which country is supplying the company with batteries most

Modules should include
1. Capital input
2. Sales
3. Transport
4. Main

Two sentences are said to rhyme, if their last two characters are the same.
For example, the following two sentences rhyme:
It's a lovely weather today
Time to feed the cow some hay
Your task is to find the rhyme scheme of a given stanza (A stanza is defined as a collection of lines). A
rhyme scheme is usually referred to by using letters to indicate which lines rhyme; lines designated
with the same letter all rhyme with each other. In other words, it is the pattern of end rhymes or lines.
http://en.wikipedia.org/wiki/Rhyme_scheme
Input:
An integer T denoting the number of stanzas to follow.
Each stanza ends with a #. The stanza itself will only contain the letters [a-z] and spaces. The last two
letters of each line will only be letters [a-z].
Output:
Rhyme scheme for each stanza on a separate line. The rhyme scheme will contain as many letters as
there are lines in the stanza. So, for example, if the stanze contains 12 lines, the rhyme scheme will
contain 12 letters.
You'll denote the rhyme scheme using the letters [A-Z].
Sample Input:
4
boat heat mat
soap globe
band robe
murder probe
mad cat#
sunday
monday
tuesday#
weather
laptop
books
summer vacations#
all
daughter
small
manner#
Sample Output:
ABBBA
AAA
ABCD
ABAB

These are common questions for programming in C and C++. Personally, I prefer C++ as a programming language. I find it easier to code in this language than in C. Anyway, I think that you have a good collection of the common questions that students are asked to answer when they are first learning the language. Thanks for sharing.

Suppose we need to collect statistics of student’s marks in C programming language course. Write down a program that will read 15 students number and will print their grade distribution (i.e., how many got A grade, how many got B grade etc.). The marks of 15 students will be input to your program. Use a one dimensional array to store marks; assume all marks are integers. Also use another one dimensional array to store the statistics about grades. For example, the number of students getting A grade will be stored at index 0, the number of students getting B grade will be stored at index 1 and so on. What will be the size of that array?
The chart for grade calculation is as follows:
Marks Grade
=========== ============
90 – 100 A
80 – 89 B
70 – 79 C
60 – 69 D
< 60 F

The English Premier League (EPL) is the main sporting event in England each year. The game is
called Soccer in Australia because we play 4 different types of football; however, most of the world
simply refer to the game as Football. The Premier League has lost the source code for the program
that reports the current table of team standings. Normally, this would not cause problems because
the compiled program will continue to work until the end of the current season, whereupon it can be
replaced.
However, there is a need to report on the relative positions of the teams just including the results
from late September or October onwards on a month by month basis (or maybe two months at a
time), so clubs can know which Managers possibly need to be replaced – something that happens
regularly when a team is underperforming. So, the program needs to be re-written in its simplest
possible form to supply this information. The program will just use simple text files for input.
You will need to write a program that allows the league to feed in a simple text file of individual
match results and produce lists that are ordered alphabetically, as well as, in team performance
order.
For the Premier League, we will use shortened team names. There are 20 teams. ?
can anyone tell me source code ?

Create a program called cashier.cpp.
Part 2. The Cashier Module
You are ready to add some of the point-of-sale functionality to your program. Currently, the cashier.cpp program displays a simulated sales slip without any sale information. Modify this program so that prior to displaying the simulated sales slip, it asks for the following data:
• The date. Expect the user to enter a date in the form MM/DD/YY. This should be entered as a string and stored in a string object variable.
• The quantity of the book being purchased: Store this number in an integer variable.
• The ISBN number of the book being purchased. The ISBN number is a string that contains numbers and hyphens. Use a string object variable to store it.
• The title of the book. Store the book title in a string object variable.
• The unit price of the book. Store this number in a floating-point variable.
