8. Concise operators

• Concise operators are roughly equivalent to binary operators. For example,

  
      ( a += c )        means      ( a = a + c )
  
      ( a *= scale )    means      ( a = a * scale )
  
      ( ++a )           means      ( a += 1 )   or   ( a = a + 1 )
  
  

• Concise operators are generally better to use. They are clearer and express an idea more directly.
