Access individual character

	Str::GetFirstChar
	STRCHAR GetFirstChar () const

Returns the first character in the string.  If the string is empty, will return 0 (the null character).

	Str::GetLastChar
	STRCHAR GetLastChar () const

Returns the last character in the string. If the string is empty, will throw an exception (error condition).

	Str::GetAt Equivalent to: operator []
	STRCHAR GetAt (CPOS idx) const STRCHAR operator[] (const CPOS idx) const

The GetAt() method, and its equivalent indexing operator, will retrieve a single character from the string at the given 0-based position. If the position is less than 0, or beyond the end of the string, the null character (0) is returned.

Example: compare a C string with a Str string character-by-character

   LPCTSTR s_src = _T("SaMpLe 123");
   Str s (s_src);
   for (int i=0; i<s.GetLength(); i++) {
      STRCHAR c1 = s_src[i];
      STRCHAR c2 = s[i];         // Equivalent to s.GetAt(i)
      ASSERT(c1 == c2);
   }
