### Objective

To get more practice with using if statements, conditions, and blocks.

For this lab, you will write a program to calculate the letter grade for this class given the numeric grade. The ranges are listed on the syllabus as:

• [92, ∞): A
• [89, 92): A-
• [87, 89): B+
• [82, 87): B
• [79, 82): B-
• [77, 79): C+
• [72, 77): C
• [69, 72): C-
• [67, 69): D+
• [60, 67): D
• [0, 60): F

Input will be the number and output will be the letter grade that would earn.

### Details

• Prompt the user to enter their numeric grade.
• Read in the value using a Scanner.
• Use if and else if statements to check each condition for the user's grade.
• For each one, output the letter grade corresponding to the numeric grade.
• If the grade entered is less than 0, print an error message.

### Sample Run

Below is a sample run of the program. Values entered by the user are shown in bold face.
