fmt.Print("Please enter principal amount: ")
fmt.Scanln(&principal)
fmt.Print("Please enter Interest Rate: ")
fmt.Scanln(&interest)
fmt.Print("Please enter period: ")
fmt.Scanln(&period)
total= (principal* interest* period) / 100
fmt.Println("\nSimple Interest Amount: ", total)
fmt.Println("\n Total Amount: ", amount+total)
}
