在公式QMm=Q(1±XQ)中,QMm为一定统计置信水平下,给出()的流量。
有如下程序: Private Sub Command1 Click() Dim a As Single Dim b As Single a=5:b=4 Call S(a,B)End Sub Sub S(x As Single,y As Single) t=x x=t\y y=t Mod y End Sub 在调用运行上述程序后,a和b的值分别为A.0 0B.1 1C.2 2D.1 2

设有如下程序: char sub(char * q) {while(* q,='\0') {if(*q>='A'&&*q<='Z')*q=* q+32; else if(*q>='a' &&*q<='z')*q=*q-32; printf("%c",*q); q++;} } main() {char *s="abcABC"; sub(s); } 则程序运行后的输出结果是( )A.ABCabcB.abcABCC.abcabcD.ABCABC
运行下列程序:Private Sub form_Click( )x = 8: y = 2Call fun1((x), y)Print x, yEnd SubPrivate Sub fun1(x, y)s = xx = s / yy = s Mod yEnd Sub单击窗体后,则在窗体上显示的结果是( )。A.4 2B.8 2C.8 0D.2 4
有如下Sub过程:Sub ind(a As Integer)Static x As Integerx= x + aPrint x:End Sub以下是调用它的事件过程,程序运行后,单击命令按纽Command1三次,输出结果为【 】。Private Sub Command1_Click()Ind 2End Sub
( 35 )在窗体中添加一个名称为 Command1 的命令按钮,然后编写如下程序:Public x As IntegerPrivate Sub Command1_Click( )x = 10Call s1Call s2MsgBox xEnd SubPrivate Sub s1( )x = x + 20End SubPrivate Sub s2( )Dim x As Integerx = x + 20End Sub窗体打开运行后,单击命令按钮,则消息框的输出结果为A ) 10B ) 30C ) 40D ) 50
