Unit 7 Pretest - Selection and Logical Expressions

Flowchart Description

1. Start

2. Input a number

3. Is the number greater than 0?

   • If Yes, display "Positive"

   • If No, go to the next decision

4. Is the number less than 0?

   • If Yes, display "Negative"

   • If No, display "Zero"

5. End

Question: If the user enters 0, what will the program display?

What will this program output?

What will this program output?

Consider this code: age = 16 if age >= 18: print("Adult") else: print("Minor") Why does the program print "Minor" instead of "Adult"?

In a flowchart, which shape represents a decision point where the program must choose between different paths?

What does a decision diamond in a flowchart typically contain?

Which flowchart structure best represents this logic: "If the temperature is above 75, display 'Hot.' Otherwise, display 'Cool.'"?

What is the result of evaluating the condition: 5 >= 5?

Why must the condition inside an if statement evaluate to either True or False?

What is the primary purpose of an else statement in a program?

What will this program print?

score = 85
if score >= 90:
print("A")
elif score >= 80:
print("B")
else:
print("C")

You need to write a program that assigns letter grades based on test scores: A for 90+, B for 80-89, C for 70-79, D for 60-69, and F for below 60. Which control structure is best suited for this task?

In an if/elif/else structure, how many code blocks can actually execute when the program runs?

Consider this scenario: A program needs to check if a number is positive, negative, or zero. Why would if/elif/else be better than using three separate if statements?

What will this program output?

num = 10 if num > 5: if num > 15: print("Very High") else: print("Medium") else:

print("Low")

If you want to check whether a student's grade is between 80 and 90 (inclusive), which condition would work?

What is the key difference between how an if/else structure and an if/elif/else structure handle multiple conditions?

What will this program output?

temp = 72 if temp > 80: print("Hot") elif temp > 60: print("Comfortable") elif temp > 40: print("Cool") else:

print("Cold")

Consider this code: password = "secret123" if password == "secret123": print("Access Granted") else: print("Access Denied") Why is the == operator used instead of = in the condition?

Which condition will be True only if both comparisons are True?

What does the or operator do?

What is the result of this expression?

(5 > 3) and (2 > 4)

What does the not operator do?

What is the result of this expression?

not (4 < 6)

What is the result of this expression?

(10 >= 10) and (5 != 3)
