Problem 1 : itspinsay

As part of a language translation program you have been asked to write a
fucntion that will create a string by removing the first letter and
making it the last letter.  This function, named Pigify, should work so
that


    cout << Pigify("slip") << endl;

will print "lips", i.e., the function returns a string.


    String Pigify(const String & word)
    // precondition: word = a1a2a3...an
    // postcondition: returns a2a3...ana1
    // 
    // this function creates and returns a string based on word
    // by 'rotating' the characters of word and making the first the last


You should write two versions of the function.  One version should use
the indexing operator [] to access characters and the
concatentation operator + to build up the new string.

The other version must work without using the indexing operator, but by
using istrstream, GetLine, and get (you can still use
the concatenation operator +).

In both functions you'll need a loop that does something like:

    String result = "";    // initialize to empty string
    
    while (...)
    {

        result += appropriate_character;

    }  
    return result;
