I believe the answer is B. Biographies and histories. (Otherwise its D)
Assuming that the message wire does not reset the bits after each sending cycle done, the message will be AABB read here for first 4 seconds.
Explanation :
As your friend is setting the bit after two seconds so the same message will be read by you when you will check second time expecting new bit set by him.
So...
After first second it will be A.
Second second it will be A again because the friend has not set the bits for new message and same message will be in the wire.
Third second the wire will have B as the bits were set this time considering the message is set by the friend after each 2 seconds.
Forth time it will be same B because no bits are set for new message in the wire.
Answer:
A
Explanation:
because if you have videos, audios and documentation you can easily see that this has structure and good explainations.
Answer: A) Constants
B) Variable
Explanation: The two basic type of operands are-
A) Constants-
constants are the value that do not change once they are defined.
As for example 5+3, here 5 and 3 are operands and + is an operator.
B) Variable-
It represents a symbolic variable name which helps in storing information in memory.
In A×B, A and B are two operands of variable type whose value can change and it is defined by user or some other dependent operation and × is a operator.
Probably (Who is the main character of the story?) because exposition " introduces the characters, describes the setting and establishes the problem in the story." Is this helpful?
