Explanation / Answer

As per Chegg plociy, I amnswering only first 4 questions:

For Q38 and 39, program is required.

40.) Since comparison operator has higher precedence than the logical operator. Therefore, given expression 3>6 && 7>4 = 0 && 1 = 0 evaluates to false. Hence option b is correct.

41.) Expression 4 * 3 < (6 + 7) && 7 < 6 + 9 = 12<13 && 7<15 = 1 && 1 evluates to true. Hence, option a is correct.

42.) Expression 7 >= 3 + 4 || 6 < 4 && 2 > 5 = 7>= 7 || 6<4 && 2>5 = 1 || 0 && 0 = 1 || 0 = 1 evaluates to true.

45.) Option b: case '3': will be the right option.
