Practice Assignment

Information

1. Write a program that prompts the user for an English word, and then prints out the value of the word based on the game of Scrabble. In the game of Scrabble, each letter is worth a certain number of points, based on the frequency with which it occurs in the language:

   Points	Letter
   1	A E I L N O R S T U
   2	D G
   3	B C M P
   4	F H V W Y
   5	K
   8	J X
   10	Q Z

   Here is the output from the program run multiple times interactively:

   Enter a word: apple
   Scrabble value is : 9
   
   Enter a word: Apple
   Scrabble value is : 9
   
   Enter a word: APPLE
   Scrabble value is : 9
   
   Enter a word: banana
   Scrabble value is : 8
   
   Enter a word: zebra
   Scrabble value is : 16
   
   Enter a word: quizzify
   Scrabble value is : 41
   
   Enter a word: Oxyphenbutazone
   Scrabble value is : 41
   

   The program only prompts for one word, prints the value, and then exits. The output above was produced by running the program 7 times.

   The name of the file should be scrabble1.c and the command to compile it will look like this:

   gcc -Werror -Wall -Wextra -ansi -pedantic -O2 -Wno-unused-result -o scrabble1 scrabble1.c
   

   Files:
   • Here's a partial scrabble.c file to get you started: HTML     Text. You'll have to rename it if you download it.

   • Here are some sample input files: input1.txt    input2.txt    input3.txt    input4.txt    input5.txt    input6.txt    input7.txt    and the output file from all of them. Run it like this:

     scrabble1 < input1.txt > myoutput.txt
     scrabble1 < input2.txt >> myoutput.txt
     scrabble1 < input3.txt >> myoutput.txt
     scrabble1 < input4.txt >> myoutput.txt
     scrabble1 < input5.txt >> myoutput.txt
     scrabble1 < input6.txt >> myoutput.txt
     scrabble1 < input7.txt >> myoutput.txt
     

     Notice the first output redirection is a single >, but the rest are double >>.

Notes

• Approximate number of lines of code: 15. There will be many case labels, but the number of executable statements is about 15.
• You don't have to worry about invalid input. You can assume that the user is only going to type in letters (lowercase a..z and/or uppercase A..Z). Use the toupper function from ctype.h to convert characters to uppercase.

• Use a switch statement to select the proper value for each character. Hint: You will have multiple cases sharing the same code for many of the letters.
• Use the function getchar from stdio.h to read each character. You'll notice that the sample code that is provided is using it to get the first letter of the word. Page 140 in the CS120 textbook shows exactly how you should use this function. Please read that. It will save you a lot of time.
• You should read characters into an int variable. (getchar returns an integer, which is the ASCII value of the character read from the keyboard.)
• You only need to include two header files (stdio.h and ctype.h) in your file.
• DO NOT UPLOAD ANYTHING UNTIL YOU HAVE TESTED YOUR CODE WITH REDIRECTION.
