A group of students is writing a program that will convert their letter grades into a 4.0 scale. For their program, they want a letter grade to be entered to be converted into the program. Which programming construct should be used to accomplish the selection and conversion?(1 point)%0D%0AResponses%0D%0A%0D%0Afor loop%0D%0Afor loop%0D%0A%0D%0Aif-then-else%0D%0Aif-then-else%0D%0A%0D%0Acondition%0D%0Acondition%0D%0A%0D%0Awhile loop%0D%0Awhile loop
The programming construct that should be used to accomplish the selection and conversion is the "if-then-else" statement.
The programming construct that should be used to accomplish the selection and conversion of letter grades is the "if-then-else" statement.
The programming construct that should be used to accomplish the selection and conversion is the "if-then-else" statement. This statement allows for conditional execution based on a certain condition. In this case, the condition would be the letter grade entered by the student.
Here's how the "if-then-else" statement can be used in this scenario:
1. Start by taking the input from the user, which is the letter grade.
2. Use the "if-then-else" statement to check the value of the letter grade and execute the corresponding code block. Each code block represents the conversion of the letter grade into a 4.0 scale.
3. Inside each code block, you can perform the necessary calculations or operations to convert the letter grade into the desired scale (e.g., assigning a specific value to the letter grade based on a predetermined scale).
4. Finally, you can output the converted grade to the user.
Here's an example in Python:
```python
letter_grade = input("Enter your letter grade: ")
if letter_grade == 'A':
converted_grade = 4.0
elif letter_grade == 'B':
converted_grade = 3.0
elif letter_grade == 'C':
converted_grade = 2.0
elif letter_grade == 'D':
converted_grade = 1.0
else:
converted_grade = 0.0
print("Equivalent 4.0 scale grade:", converted_grade)
```
In this example, the program takes the input letter grade and uses the "if-then-else" construct to determine the equivalent 4.0 scale grade. The converted grade is then printed as the output.
