Question description

8)  Write a program to compute various offensive statistics on baseball.   The following information
      will be available on each player:

      Number of Walks (BB), Strike Outs (SO), Hit by Pitch (HP), Sac Flys (SF), Singles,
          Doubles (2B), Triples (3B), and Home Runs (HR) as well as Number of At Bats (AB).

Based on this information, develop a set of functions within your program that will compute the following:

      Total Bases, Batting Average, Home Run Ratio, Strike Out Ratio, On Base Percentage, and Slugging Average.

You do not need to be a baseball fan to do this ... All the information you need in
terms of the formulas and explanations can be found at:


Note: Number of hits is: singles + doubles + triples + home runs

9) Most people enjoy watching movies these days, whether its the classics or modern ones.  
Develop a set of structures that could be used to model the information about a movie collection.  
What type of information would you want to collect and store about a movie?   What would be the right
types in C for that information? Define supporting structures as needed and have one final structure type that
is made up of various members (some members may be on some structure type, others may be simple integers,
floats, chars, arrays, etc).

No program is needed although you might want to create a simple main function
and include your structure types just to test that everything compiles.

This question is similar to the final question on the midterm, but you have learned about many different
types since then.  Here is a template to use to get started and indicates what I am looking for in your answer.
Use everything you learned this semester, especially types from the last set of lectures notes.
      /* add supporting structures - expect many structure types here ... date is good example */

struct date
int month;
int day;
int year;

/* add other supporting structures */  
      /* Final structure, such as struct movie */
struct movie
             /* some members may be a structure type themselves, here is an example */
struct date releaseDate; /* the date the movie was released */
             /* other members may be ints, floats, doubles, chars, enum, ...  */
char title [100]; /* the title of the move */

/* add others */

      int main  (  )
             struct movie myMovie [1000];   
             /* nothing else needs to be added to main */
             return (0);

The National Football League (NFL)  is currently investigating whether the Patriots, Colts, or any 
other entity purposely deflated footballs during this year's AFC Championship game.
Not so fast says Professor Bill Belicheck of the Foxboro Institute of Technology (FIT).  He claims that it 
is natural for a football starting with a PSI of 12.5 to easily deflate during the game using Guy-Lussac's
Laws.  Given that it was raining that day, water pressure vapor is another variable to be considered.

Your job if you choose to accept it is to use the information in the the link(s) below to create a function or 
set of functions that could be called to support Professor Bellichek's position that a ball starting at a PSI of
12.5 could easily deflate to 12.1 given the game time temperature of 51 degrees, and down to 11.7 considering 
the water pressure vapor in the air caused by the rain.    Pass in parameters such as temperate, water and air 
pressure, and other factors to your functions(s), so that the NFL could model any conditions in the future
with their footballs.

1) Write a macro for each of the following. DO NOT provide a function ... I am looking for a macro (see last set of lecture notes).

a) Area of a Circle b) Area of a Square c) Area of a Rectangle d) Area of a Triangle You can find formulas and detailed explanations at: http://www.mathisfun.com2) Write a function which will determine how many words are in a given string. You can assume that one or more consecutive white spaces is a delimiter between words, and that the string you pass to your function is null terminated. 3) Write a function that is passed a month, day, and year and will determine if that date is valid. You can assume each parameter is passed in as an integer. Remember to check for leap year! validDate (5, 31, 1961) .... would be valid validDate (13, 4, 1967) ... would be invalid, the month is invalid 4) Write a function that takes the values of a two-card blackjack hands as input, and returns the point total of the hand. The value of the cards '2' through '9' is equal to their face value, the cards 'T', 'K', 'Q', 'J' are worth 10 points and the ace ('A') is worth 11 points unless it comes with another ace, then that second ace is worth 1 point. The program should be able to catch incorrect input.     Enter cards: A Q    The score is 21    Enter cards: A A    The score is 12    Enter cards: T 7    The score is 17     Enter cards: A 5    The score is 16    Enter cards: 7 #    *** Would be invalid, # is not a valid card    Enter cards: Z 4    *** Would be invalid, Z is not a valid card Hint:  I've used a value of 'T' for the 10 card so you can simply pass in two characters, instead of strings, as parameters to this function.    5) Write a function to determine is a given word is legal.   A word is illegal if it contains no vowels. For this problem,         the letter Y is considered to be a legal vowel.   Pass in a word to this function and it will determine if the word is         legal or not.   You can make the following assumptions about the word you a passing to this function.          1) The string being passed is a combination of letters only (no non-letter check needed)          2) The string being passed is null terminated          3) Letters may be capital or lower case and it has no effect on whether its a word          Examples:                    sch  - is illegal, no vowels                             apple - legal, contains a vowel                  APPle - legal, uppercase letter combinations do not matter                           try - legal, no vowel, but contains the letter 'y'   6) Write a function that will determine if a given string is a palindrome. DO NOT use the C library function: strrev A palindrome is a word or sentence that reads the same forward as it does backward. Examples of word palindromes would be civic or rotor ... a word or phase would be:                Never odd or even A good web site of examples is: http://www.rinkworks.com/words/palindromes.shtml 7) Write a function that will return in a structure the following characteristics of a given string: 1) string length (use strlen), 2) number of upper case characters 3) number of lower case characters, 4) number of digits 5) number of blank spaces 6) number of non-alphanumeric characters.
