[填空题] 设有以下函数过程：Function fun(m As Integer) As Integer Dim k As Integer, sum As Integer sum = 0 For k = m To 1 Step -2sum = sum + k Next kfun = sumEnd Function若在程序中用语句s=fun(10)调用此函数，则s的值为 _________。
参考答案：
30问题解析:
在 For 循环中，Step 是用于指定计数器的步长，本题中是-2，就是每执行一次循环后，k 的值减 2。 本题中从 10 开始执行循环，当 k=0 时，结束循环。此时 s=10+8+6+4+2=30。
