Visual Basic Give that two Integer variables, total and amount have been declared, write a loop that reads non$-$negative values into amount and adds them into total. The loop terminates when a value less than $0$ is read into amount. Don't forget to initialize total to $0.$

To read a value into amount use a method, getNum$()$ that we provide for you a class named TC:

amount $=$ TC$.$getNum$()$;
