To figure out expressions like that start with the precedence table:

  • Multiplication has precedence of 3, so it will be evaluated first
  • != has precedence of 7, so it will be evaluated next
  • += has precedence of 14, so it will be evaluated last.

Therefore, x will be incremented by 1 if y*2 is not equal to z.

It should be

x += ((y*2) != z);
