Question

Make a C program to count the number of occurrences of words from the input. For example, with input "one two one three one two" your program should output:
one 3
two 2
three 1

It should work for up to 100 different words. If there are more than 100 unique words in the input, the program should still work, and count the number of appearances of the first 100 unique words. Each word should have the same maximum amount of characters allocated. Assume these are English words (not place-names) so if you know the longest word in English, you know what to set the maximum to. Also, words must start with a letter. Thus "123" would be ignored since it is not a word, but "abc123" would be counted as a word. Convert all upper-case letters to lower-case. Ignore punctuation, except for single quotes, and dashes. Thus, the input:

I said: "one's favorite, or *best-liked* coffee? (I don't know.)"

would be treated the same as

i said one's favorite or best-liked coffee i don't know

by your program.

Read the words from standard-input until there is no more to read. Then output the words and word counts to standard output. If a word is too long to fit, truncate it.
