Question

It the sub-expression on the left of the && logical operator is, the right sub-expression is not checked. If the sub-expression on the left of the || logical operator is, the right sub-expression is not checked. The logical operator has higher precedence than the other logical operators. Logical operators have precedence than relational operators. The logical operator works best when testing a number to determine if it is within a range. The logical operator works best when testing a number to determine if it is outside a range. A variable with scope is only visible when the program is executing in the block

Explanation / Answer

7. The answer is false.

Explanation : The logical AND(&&) operator only returns true if the
left and right expressions of the && opertor are true otherwise it returns false.
If the left side of the expression is false then it is optional or not necessary to check right side

since the logical AND evaluates to false irrespecitve of the right side expression.

8. The answer is true.

Explanation : The logical OR(||) operator only returns true if either
of left or right expressions of the || opertor are true otherwise it returns false.
If the left side of the expression is true then it is optional or not necessary to check right side since

the logical OR evaluates to true irrespecitve of the right side expression.

9. The answer is logical NOT(!).
Explanation:
Logical NOt (!) operator has higher predence over other logical operators && and ||.

10. The answer is lower precedence.

Explanation: The logical operators are logical AND and logical OR opeators.
The relational operators are <, <=,>,>= .After the relational operators ar executed
then the logical operators are gets executed.

11.

The answer is logical && operator.

Explanation: The logical AND operator (&&) works best to test
a number is with-in a range .
Example : The expression checks if the number is within 0 and 100
number>0 && number<100

12.

The answer is logical || operator.

Explanation: The logical OR operator (||) works best to test
a number is outside of range .
Example : The expression checks if the number is outside of 0 and 100
number<0 || number>100 then the number is out side of the range 0-100

13. The correc answer is block.

Explantion:
A variable declared in side the block has local scope.
The accessibility of the variable only within the block.
It is not accessble to outside of the block.
