Explanation by: Admin
Operator | returns true if any one operand is true, thus ‘r = true | false’ is true. Operator & returns p true if both of the operand is true thus s is false. Ternary operator ?: assigns left of ‘:’ if condition is true and right hand of ‘:’ if condition is false. z is false thus z = s ? q : r , assigns r to z , z contains true.
output: false true
