1.設有如下兩組資料:
(1)1,3,5,2,4,18,50,25
(2)5,27,30,35,60,41,87,33
編寫一個程式,把上面兩組資料分別讀入兩個陣列中,然後把兩個陣列中對應下標的元素相加,即1+5,3+27,……,25+33,並把相應的結果放入第三個陣列中,最後輸出第三個陣列的值
**private sub command1_click()
dim i
dim x()
dim y()
dim z(0 to 7)
x = array(1, 3, 5, 2, 4, 18, 50, 25)
y = array(5, 27, 30, 35, 60, 41, 87, 33)
for i = 0 to 7
z(i) = x(i) + y(i)
print z(i);

next j
next i
x = a(1, 1)
for i = 1 to 10
for j = 1 to 10
if a(i, j) > x then m = i: n = j: x = a(i, j)
next j
next i
print "最大數為:" & x & ",它為第 " & m & "行," & "第" & n & "列的元素。"

4.輸入若干個學生的一門課的成績,統計各分數段的人數。按小於60分、60~69分、70~79分、80~89分、90~100分各為一個分數段。
**private sub command1_click()
dim a$(), k%, y
dim x(0 to 10) as integer
a = split(text1.text, ",")
for each y in a
k = y \ 10
x(k) = x(k) + 1
next y
