4 8. What is the correct way to write the condition c < r < z? a. (c< r< z) b. ( (c< r) && z) c. ((c> r) (c < z)) d. ((c < r) && (r< z)) 9. If x is 0, what is the value of (!x ==0)? a. false b. true c. unable to determine d Which of the following cannot be checked in a switch-case statement? a. character b. float c. integer d. All of the above 11. Which of the following are valid case statements in a switch? a. case 1: b. case x<4: c. case abc : d. case 1.5: 12. int r[3][4]; will have how many element in the array? a. 7 b. 12 c. 9 d Which of the following is correct for = and ==? e. = use in conditional operation while == use in mathematical operation. f. = and == used in program representing equal. g. == use only in conditional operation while = in mathematical operation. h. = and == is a type of function.
