CS157 HW2: Baseball!                

For this assignment, you will write a program called bb.c, which will help you manage your baseball team.                 

You don’t have to keep track of much: each player has a name, a player number, and a batting average.                 

Data Structures                

You must store the team as an array of structures. The array must not be a global variable.                 

Sample Run                

Here is a sample run. Your output must match exactly. User input looks like this.                 

    % ./a.out
    Please rise for our national anthem.

    a name number average (add a player)
    h (help)
    q (quit)
    p (print all players)
    p number (print a single player)

    Command: p
    Player   Num Average
    ======== === =======

    Command: a Jack 12 42

    Command: a Theresa 40 300

    Command: a Babe 3 342

    Command: p
    Player   Num Average
    ======== === =======
    Jack     12  .042
    Theresa  40  .300
    Babe     3   .342

    Command: p 40
    Player   Num Average
    ======== === =======
    Theresa  40  .300

    Command: p 99
    Player   Num Average
    ======== === =======

    Command: a Lou 3 125
    The team already has a player #3.

    Command: p
    Player   Num Average
    ======== === =======
    Jack     12  .042
    Theresa  40  .300
    Babe     3   .342

    Command: z
    Bad command 'z'.
    a name number average (add a player)
    h (help)
    q (quit)
    p (print all players)
    p number (print a single player)

    Command: h
    a name number average (add a player)
    h (help)
    q (quit)
    p (print all players)
    p number (print a single player)

    Command: q

Requirements                

• Each input line will be no more than sixty characters long.
• You may assume that the user will enter syntactically valid input. However, the user may enter a bad command, such as “z”, or a duplicate player number, and you must deal with that.
• Duplicate player names or averages are OK.
• Your program must process requests until a “q” command is entered.
• There may be no more than nine players on the team. If the user tries to add any more than that, the program must say “Sorry: the team is full.”
• Each player name will be a single word, no more than eight characters long. For example, “Maryanne” is a valid name. Don’t forget to reserve space for a trailing null character!
• Player numbers will be 0-99.
• Batting averages will be entered as 000 to 999. Note that they’re printed like this: .042
• Use functions. Do not put everything in main.
• Global types and #defines are fine.
• NO global variables!

Notes                

You will lose points if your program:

• doesn’t compile
• doesn’t work
• isn’t named bb.c
• uses language features that we have not yet covered
• changes any of the prompts or messages
• does fopen without fclose
