The C Programming K&R Exercise 1-11
c
Solution
The program you posted treats everything which is delimited by whitespace as a word. So these are all words: `12` `a,b123456` `2-3@!#`.
It asks you to improve the program with a better definition of word, and gives an example: "a sequence of letters,digits and apostrophes that begins with a letter".
So with this example `John's` and `a123` is a word, but `12`, `1a` and `a-b` aren't.
Problem
I'm currently coming thru Word Counting program . And i got a tricky Exercise. I can't understand what exactly this exercise want me to do . Here the Exercise itself Revise the word counting program to use better definition of "word," for example, a sequence of letters,digits and apostrophes that begins with a letter I cant get what it actually want .It want me to count symbols digits apostrophes or ether it want me to put names for all those symbols digits etc. like "word," - will be `A(") word comma(,) A(")` or there something else. This is the program which counts lines, characters, and new lines ``` #include <stdio.h> #define YES 1 #define NO 0 main () { // CTRL+Z will Signal to EOF-End of File int c,nl,nw,nc,inword; //nl -new line //nw -new word //nc -new chatacter //inword -program in word or not inword=NO; nl=nw=nc=0; while ((c=getchar()) !=EOF) { ++nc; if (c == '\n') ++nl; if (c == ' ' || c == '\t' || c == '\n') inword=NO; else if (inword==NO) { inword=YES; ++nw; } } printf("%d %d %d\n", nl,nw,nc); getchar(); } ``` Can you guys explain to me what actually the Exercise want me to do? I don't need already complete code. Iwant to go thru the coding myself. I just don't get what i actually need to do here in Exercise.
