Answer

int z = (int)'x';

Reason

  1. int x = "GOOD"; — "GOOD" is a String literal, not an integer. We cannot assign a String to a variable of type int.
  2. int y = 45.0/2; — 45.0 is a double literal, so the result of the division is a double. Assigning a double value to an int without explicit typecasting causes a type mismatch error.
  3. int z = (int)'x'; — This is a valid initialization because the character 'x' is explicitly typecast to an integer, storing its Unicode value in the variable z.
  4. int m = false ; — false is a boolean literal. We cannot assign a boolean value to a variable of type int.
