A switch case is a statement that allows the variable to be compared to a set of variables. Each value is referred to as a case, and the variable is tested for each case. It is also a substitute for the If-Else-If Statement.

How the code works?

Choices 1: Given the code, if we type choices A, we are now able to test the Grading System . By simply inputting the 1st, 2nd and 3rd grading and to compute for the Average.
