  • 第1题:

    下列程序段执行以后,内存变量Y的值是( )。 CLEAR x=12345 y=O DO WHILE x>0 y=y+x%10 x=int(x/l0) ENDDo ?Y

    A.54321

    B.12345

    C.51

    D.15


    正确答案:D
    D。【解析】程序的功能是从个位起依次读取各位上的数并求和,最终的结果为l5。

  • 第2题:

    已知float x=2.23,y=4.35;,根据下面的输出结果,正确的程序段是()。 x=2.230000,y=4.350000 y+x=6.58,y-x=2.12

    A.printf("x=%8.2f,y=%8.2f",x,y); printf("y+x=%4.2f,y-x=%4.2fn",y+x,y-x);

    B.printf("x=%8.6f,y=%8.6fn",x,y); printf("y+x=%4.2f,y-x=%4.2fn",y+x,y-x);

    C.printf("x=%7.2f,y=%7.2fn",x,y); printf("y+x=%3.2f,y=%3.2fn",y+x,y-x);

    D.printf("x=%f,y=%fn",&x,&y); printf("y+x=%f,y=%fn",y+x,y-x);

  • 第4题:

    (33)有如下事件程序,运行该程序后输出结果是

    Private Sub Command33_Click()

    Dim x As Integer,y As Integer

    x=1:y=0

    Do Until y<=25

    y=y+x*x

    x=x+1
