words

Little program that reads standard input and prints some statistics. Tested only on Linux.

Disclaimer: Not really a C programmer, just felt like tinkering with it a little :-)

Building

You'll need CMake 2.8.4+ and a C compiler that can handle C99. Run the following in command line while in project root:

$ cmake . && make

This should output a binary called words in the project directory.

Or, alternatively, if you'd rather not use cmake for such a trivial program, the following works too (if you have GCC installed):

$ gcc -std=c99 main.c dyn_str.c -o words

Usage

Run the following in directory where you compiled the binary:

$ echo -n "hai linux" | ./words
Reverse: xunil iah
Words: 2
Length: 9

$ echo -n "nisumaa oli isäsi ilo aamusin" | ./words
Reverse: nisumaa oli isäsi ilo aamusin
Words: 5
Length: 29

Or you can use <<< to redirect a string to stdin, but it seems to add a newline to the end unlike echo -n:

$ ./words <<< "Hello!"
Reverse:
!elloH
Words: 1
Length: 7

You use files as an input also:

$ ./words < HelloWorld.txt
Reverse: 
!dlrow ,olleH
Words: 2
Length: 14

Or just type to standard input and press Ctrl+D when you're ready:

$ ./words
Hello, world!
Reverse: 
!dlrow ,olleH
Words: 2
Length: 14

All whitespace (spaces, newlines) are added to length.
