14. Template arguments

• Templates can have more than one argument.

• Templates can have different kinds of arguments.

• Non-class arguments must be supplied with constants:

  
  template< typename ValueT, int SIZE >
  class FixedSizeBuffer {
  
      ValueT m_buffer[ SIZE ];
      int m_size;
  
  public:
      FixedSizeBuffer() : m_size( SIZE ) {}
  };//class FixedSizeBuffer
  
  FixedSizeBuffer< char, 80 > line; // ValueT is char, SIZE is 80
  FixedSizeBuffer< string, 10 > sb; // ValueT is string, SIZE is 10
