count the number of lines, words, and characters within an input

Question

Right now I am going through a book on C and have come across an example in the book which I cannot get to work.

#include 
#define IN 1
#defin         


        

Answer 1

I usually handle this kind of input like this (for Linux): 1. make a file (for example, named "input.txt"), type your input and save 2. use a pipe to send the text to your application (here assume your application named "a.out" and in the current directory):

cat input.txt | ./a.out

you'll see the program running correctly.
