These kind of questions are about language usage, so should be asked in 
comp.lang.c or comp.lang.c.moderated.  This forum is for 
language-independent programming issues, such as algorithms.


I am assuming you have
#include <stdio.h>

Using a subscript of 1 accesses the second pointer to char in the array, 
etc.

You can use strlen() to get the number of characters in the string 
preceding the terminating null.  It will yield 3 and 6, respectively, 
for your example strings.  You need to include header <string.h>.
