Answers
The given questions involve binary number conversions, BCD codes, gray codes, and logic functions. The answers are as follows: (1) D, (2) A, (3) A, (4) B, (5) B.
To convert the binary number (11 1011)₂ to hexadecimal, we group the bits into groups of four and convert each group to its hexadecimal equivalent. The result is (8D)₁₆, so the answer is D.To find the one's complement of the binary number (-1101 1111)₂, we simply flip each bit. The result is (1 0010 0000)₂, so the answer is A.The 8421 BCD code (1000)₈ is equivalent to the 5421 BCD code. Therefore, the answer is A.The 2-bit gray code has 4 values: {00, 01, 11, 10}. So, the missing value is 10, and the answer is D.The logic function F₁ = (A+B) (A+C) can be simplified to F₂ = A + BC using Boolean algebra. Therefore, the answer is B.These answers are derived from the given options and the rules associated with binary conversions, BCD codes, gray codes, and logic simplification.

b. false. In C++, some operators can be overloaded as member functions of a class, but not all operators.
Unary operators like increment (++) and decrement (--) can be overloaded as member functions, but binary operators like addition (+) and subtraction (-) cannot be overloaded as member functions. In C++, not all operators can be overloaded as member functions of a class. Some operators, such as the scope resolution operator (::) and the ternary conditional operator (?:), cannot be overloaded. Additionally, operators like the assignment operator (=) and the function call operator () have special rules for overloading. While many operators can be overloaded as member functions, there are some operators that cannot be overloaded, and others that have special rules for overloading.

Answers
Answer: count
Explanation:
Given the program :
>>> aList = [3, 10, 10, 10, 30, 30]
>>> aList. ___(10)
To obtain a value of 3 on the next line, we use the count function :
aList.count(10)
The above statement returns the number of occurrences of digit 10 in the list aList. Digit 10 occurs 3 times in the list. Hence, output will be 3
The index function returns the lowest index where the digit 10 appears and thus it will give an output of 1
The pop function to used to deletes item belonging to a specified index and returns the item which is removed, for this exercise, selecting the pop function will throw an error as the list does not have any item with the index 10.

count does exactly what it is inteded for...count, counts.
