问答题Is y between 1 and 2, exclusive?　　(1) y2 is less than y　　(2) y2+y is between 1 and 2, exclusive

代数式|e3×a+1gy13+siny2|对应的Visual Bask表达式是( )。

A．Abs(e^3*a+1g(y1^3)+1/sin(y2))

B．Abs(Exp(3)*a+Log(y1^3)/Log(10)+sin(y2))

C．Abs(Exp(3)*a+Log(y1^3)+sin(y2))

D．Abs(Exp(3)*a+Log(y1^3)+1/sin(y2))

程序段如下，当发生Form_Click事件时，窗体上输出的结果是( )。 Option Explicit Private x As Integer Public y As Integer Sub Test() Dim y as integer x=2：y=2 Print"x1=";x;"y1=";y End Sub Private Sub Form_Click() x=1：y=1 Test Print "X2="；x；"y2="；y End Sub

A．x1=2 y1=2 x2=2 y2=1

B．x1=2 y1=2 x2=2 y2=2

C．x1=2 y1=1 x2=2 y2=2

D．x1=2 y1=1 x2=2 y2=1

以下程序中，函数fun的功能是计算x2(上标)-2x＋6，主函数中将调用fun函数计算：

y1=(x＋8)2(上标)-2(x＋8)＋6

y2=sin2(上标)(x)-2sin(x)＋6

请填空。

include "math.h"

double fun(double x){ return (x*x-2*x＋6);}

main()

{ double x,y1,y2;

printf("Enter x:"); scanf("%1f",&x);

y1=fim([ ]);

y2=run([ ]);

printf("y1=%1f,y2=%1f\n",y1,y2);

}
