Answer 1

Answer:

(d) -32768 to 32767 is the correct answer

Answer 2

Answer:

The output of the given code is 5 7 1.

Explanation:

• The first line of the code declares and initializes the variables used in the program.
• There are three variables a=5, b=6, and c which is not initialized.
• The next line contains a series of boolean expressions whose result is assigned to the variable c.
• The expression first checks whether the value of variable b is equal to 6 or not. If the value is equal to 6, then the result is logic high (1). If not, the result is logic low (0).
• Initially, as b=6, the result is logic high(1). The value of b is then incremented to b=7.
• Now, the expression first decrements the value of a to a=4 and then checks whether this value is less than 2 or not. If the value is less than 2, then the result is logic high(1). If not, the result is logic low(0).
• The value of a after decrementing is 4, which is less than 2. Therefore, the result is logic low(0).
• These two results are then logically ORed. As per the truth table of the OR gate, a logic high(1) and logic low(0) inputs will give the output as logic high(1). This value is assigned to variable c.
• The final values of a, b, and c are printed.

The final values of a, b, and c that is printed are 5, 7, and 1.
