  1. (10 pts) Read today's lecture notes. Honestly declare how you read the notes.
    1. (10 pts) I read the notes carefully. I have a good understanding of the topics therein.
    2. (10 pts) I read the notes carefully, but I don't really understand the following points well:
    3. (0 pts) I didn't read the notes carefully.
  2. [90pts] Write a program hw.c that works as follows:
    1. It reads in lower-case words, ending with the word "END"
    2. Then, it stores them in a linked list.
    3. Then, it reads in a single letter.
    4. Then, it prints out all words that start with that letter, in reverse order from how they were read in.

    Tip:

    • Use a static array of characters when dealing with a string. E.g. 
      char s[128];
    • You probably need to use strcpy, strcmp, and strlen functions. Do include string.h
    • scanf doesn't skip space when reading a char unless it is told to do so. 
      
// DON'T DO THIS TO READ A CHAR
scanf("%c", &c);
// BUT DO THIS
scanf(" %c", &c); //" " before %c tells scanf to skip whitespace
    		Example runs: 
    ~/$ ./hw
Enter words followed by END:
one two three four five six seven eight END
What letter? t
three
two

~/$ ./hw
Enter words followed by END:
aa ab ac ad END
What letter? a
ad
ac
ab
aa

~/$ ./hw
Enter words followed by END:
aa ab ac ad END
What letter? b
