1.
Repeatedly read in integers until -999 is typed
in. Print out the number of integers typed in. The last number, -999, does not
count. (個數)

2.
Same condition as the previous problem, but print out the sum of these
integers instead. (總和)

3.
Same condition as before, print out the average of these integers. Take
proper action when no integer is read in. (平均數)

4.
Same condition as before, print out the number of those integers that are positive. (正數個數)

5.
Same condition as before, print out the sum of those integers that are positive. (正數總和)

6.
Same condition as before, print out the average of those integers that are positive. Take proper action when no positive integer
is typed in. (正數平均數)

7.
Same condition as before, print out the value of the largest integer typed
in. (最大數)

8.
Same condition as before, print out the value of the smallest integer
typed in. (最小數)

9.
Same condition as before, print out the number of times the integer 11
appears in the input. (11出現次數)

10.
Same condition as before, print out the number of times the largest value found
in Problem 7 appears in the input. (最大數出現次數) (Do not use an array because
it is not yet covered.)
