Enter a Letter grade: B-
The numeric value is 2.7
- Your code with comments
- A screenshot of the execution
Test Cases:
           B-  (should print 2.7)
           A+ (should print 4.0)
           B+ (should print 3.3)
           C   (should print 2.0)
           F+ (should print 0.0)
           G   (should print “no such gradeâ€)
