Write a program (called Grades) that translates a number between 0 and 4 into the closest letter grade. For example, the number 2.8 (which might have been the average of several grades) would be converted to B-. Break ties in favor of the better grade; for example 2.85 should be a B. Here's a sample run of such a program: Enter numeric score then press Enter : 3.85 A Enter numeric score then press Enter : 3.84 A- Enter numeric score then press Enter : 3.5 A- Enter numeric score then press Enter : 3.49 B+ Enter numeric score then press Enter : 3.1 B Enter numeric score then press Enter : 10 A+ Enter numeric score then press Enter : -2 Enter numeric score then press Enter : -0.5
