Answer:
Point A: Always True
Point B: Sometimes false
Point C: Always False
Explanation:
In the given code snippet. Point A is the first statement within the While loop the statement System.out.println("Welcome to Java!"); will only be executed if the while condition evaluates to true.
At Point B, The statement count++ increases the value of the counter at every iteration, while it will be true for most occasions, at the last increament, this statement will be false that is at count=100, The condition will be false at this point just before program execution breaks out of the loop
Point C is outside of the loop, this happens when the given condition is no longer true.

Answer:
The answer to this question is given below in the explanation section.
Explanation:
The given compound statement are:
4 < 3 and 5 < 10
4 <3 or 5 < 10
not (5 > 13)
4 < 3 and 5 < 10 this statement is false because "and" logical operator required that both operand (4<3) and (5<10) are true. Statement (4<3) is a false statement so this statement is false. "and" operator becomes true when all its inputs are true otherwise it becomes false.
4 < 3 or 5 < 10 this statement is true because "or" logical operator to be true if one of its input is true and false when all inputs are false. so in this compound statement, the first statement is false and the second statement is true. so this compound statement is true.
not(5>13) this compound statement is true because it has "not" operator and "not" operator makes a false statement to true and vice versa. so (5>13) is a false statement, and when you append "not" operator before it, then this compound statement will become true statement, so this is a true statement.
