 When we multiply different numbers they come with different sign such as (Plus (+), Negative (-)) suppose : (-2) * (+2) = -4, your task is to write such an application that show(Display) the sign of four real number after multiplication by using sequence of if operator.[Note you can’t calculate it]

Define a class (Name, Father name, Roll num, session, GPA, address, semester) and store the record of 10 students in c# windows Application. One should be able to search by name, roll num, session and GPA. Searched data should be displayed in the decesding order
