1) Given that two int variables, total and amount, have been declared, write a sequence of statements that:

initializes total to 0

reads three values into amount, one at a time.

After each value is read in to amount, it is added to the value in total (that is, total is incremented by the value in amount).

2)

Given that two int 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.

3) Given an int variable i that has already been declared, write a for loop that prints the integers 0 through 39, separated by spaces. Use no variables other than i.
