Progression towards C style

Conventional style

      sum = sum + *y;
      y = y + 1;

Use add-and-assign operator

      sum += *y;
      y = y + 1;

Use postfix increment operator

      sum += *y;
      y++;

Combine postfix and dereference

      sum += *y++;

• it takes some time to get used to this style

• don't do it if you are not comfortable with it

• the compiler will generate the same machine instructions either way
