11. Arithmetic Assignment Examples

• Statements that use the short-hand assignment operators to get the same results:

  
  count += 1;           // count is increased by 1
  count -= 1;           // count is decreased by 1
  total += 100.0;       // total is increased by 100.0
  total -= 100.0;       // total is decreased by 100.0
  price *= .8;          // price is multipled by .8
  sum += nextNumber;    // sum is increased by the value
                        // of nextNumber
