Q.1)) (12.5 marks) Given the values below, what is the value of each of the following expressions (0 or 1)? INTEGER :: age=34, old=92, young=16 1. age /= old 2- (age==56.AND. old/=92) 3- (age--56.OR. old/=92) 4- (age==56.OR. (.NOT.(old/=92))) 5-.NOT. (age==56.OR. old=92) 6- (young<old).NEQ.(young>=16) 7- young age<old 8-.NOT.(young/=old) (125 marke

Answer 1

Integer :: age = 34, old = 92, young = 16

1. age /= old -> 0 Reason : age and old are integer variables, Their division will result in a floating point number but the it will only store the integer part of the number[i.e, value before decimal point]. age = age / old => age = 34 / 92 => 0 [34/92 = 0.395652, but it will only store 0]

2. (age == 56 AND old /= 92) -> 0 Reason : age is equals to 32. That means, age == 56 is a false statement it will result in 0. old /= 92 will result in 1 but will not make any difference because: 0 AND 1 = 0

3. (age == 56 OR old /= 92) -> 1 Reason : age is equals to 32. That means, age == 56 is a false statement it will result in 0. old /= 92 will result in 1.But we are dealing with OR operator here and we know that: 0 OR 1 = 1

4. (age == 56 OR (NOT(old /= 92)) -> 0 Reason : age is equals to 32. That means, age == 56 is a false statement it will result in 0. old /= 92 will result in 1 but NOT operator will invert the result that means 1 will become 0 and we know that 0 OR 0 = 0.

5. NOT((age == 56 OR old /= 92)) -> 0 Reason : age is equals to 32. That means, age == 56 is a false statement it will result in 0. old /= 92 will result in 1. But the NOT operator outside the whole statement will negate the result and we will get 0.

6. (young < old) NEQ (young >= 16) -> 0 Reason : young is less than old this statement is true and will result in 1. young >= 16 is also true and will result in 1 but NEQ means not equals to i.e., 1 != 1 ,and this is a false satement therefore it will result in 0.

7. young<age<old -> 1 Reason : young is less than age(16<34) and age is less than old(34<92)

8. NOT(young /= old) -> 1 Reason : young /= old will result in 0 but after negating it we will get 1.
