More on Strings
Because strings are arrays, and because array names are basically pointers, the assignment and comparison operations manipulate pointers, and not the strings themselves.
char s[ ]= �hello�;
char t[ ]= s; /* s and t point to same place*/
s[1]= �?�;
/* s and t are now �h?llo� */

Standard library strlib.h contains routines to copy string values, catenate them, compare them, etc.
