TCHAR GetAt( int nIndex ) const;
A TCHAR containing the character at the specified position in the string.
Zero-based index of the character in the CString object. The nIndex parameter must be greater than or equal to 0 and less than the value returned by GetLength. The Debug version of the Microsoft Foundation Class Library validates the bounds of nIndex; the Release version does not.
You can think of a CString object as an array of characters. The GetAt member function returns a single character specified by an index number. The overloaded subscript () operator is a convenient alias for GetAt.
The following example demonstrates the use of CString::GetAt.
// example for CString::GetAt CString s( "abcdef" ); ASSERT( s.GetAt(2) == 'c' );
