Assignment Operators

• Assignment operators permit a more concise description of certain kinds of assignments.
• c = c + 3 (assign the value of c + 3 to c) can be written more naturally as c +=3 (increment c by 3).

   

  Assignment operator	Sample expression	Explanation
  +=	c += 7	c = c + 7
  -=	d -= 4	d = d - 4
  *=	e *= 5	e = e * 5
  /=	f /= 3	f = f / 3
  %=	g %= 9	g = g % 9

• Let c = 5.
• Question: Is c *= 3 + 7 equal to c = c * 3 + 7 or c = c * (3 + 7) ?
• How might you verify your answer?
