Answer 1

To convert letter grades into a 4.0 scale based on user input, the most appropriate programming construct to use would be the if-then-else statement. This construct allows you to evaluate the input letter grade and execute different code blocks depending on the grade entered.

For example, you could use it like this:

grade = input("Enter your letter grade: ")

if grade == "A":
    gpa = 4.0
elif grade == "A-":
    gpa = 3.7
elif grade == "B+":
    gpa = 3.3
# Add other conditions as necessary
else:
    gpa = 0.0  # or some error handling

print(f"Your GPA is: {gpa}")

So, the answer is if-then-else.
