Homework #13:  Isitsame()


     Write a predicate function (one that returns true or false), 
Isitsame(), that receives two strings and compares them lexico-
graphically (that is, alphabetically according to the ASCII character 
set).   If the two strings represent the same text, independent of 
the case of the letters, the function returns true(1).  Otherwise, 
the function returns false(0).  Consider the two strings "Hello" 
and "hello".  Isitsame() should return true.  However, comparing 
the two strings "Hello" and "hell", the function should return false.

	int Isitsame(const char *,const char *);

Note:  the const prefix to char * means that your function must NOT
change the strings sent to it.

     To write the function Isitsame(), you may wish to use either
functions char toupper(char ), which converts characters to upper case,
or char tolower(char) which converts characters to lower case.  Both
of these functions are found in the standard library.  However,
you may not use any functions declared in string.h .  The purpose of 
this assignment is to give you experience manipulating strings.  You
may, of course, write your own private functions which mimic the
behavior of functions in the string library (just don't use the
same names!!)

      After you complete this assignment, you will probably have
a much greater appreciation for the functions in the string library.
