下面____程序段不能正确显示1!、2!、3!、4!的值。 A: For I=1 To 4 n=1 For j=1 to I n=n*j Next j Print n Next I B: For I=1 To 4 For j=1 to I n=1 n=n*j Next j Print n Next I C: n=1 For j=1 to 4 n=n*j Print n Next j D: n=1:j=1 Do While j<=4 n=n*j Print n j=j+1Loop

下列程序段不能正确显示1！、2！、3！、4！的结果的是 。 A: For i = 1 To 4 For j = 1 To i n = 1 n = n * j Next j MsgBox( n)Next i B: Dim i%, j%, n%For i = 1 To 4 n = 1 For j = 1 To i n = n * j Next j MsgBox( n)Next i C: Dim j%, n%n = 1For j = 1 To 4 n = n * j MsgBox( n)Next j D: Dim j%, n%n = 1j = 1Do While j<=4 n=n*j MsgBox(n) j=j+1Loop E: Dim j%, n%n = 1j = 1Do n=n*j MsgBox(n) j=j+1Loop While j<=4

若排列38i7j625为奇排列，则i=（ ），j=（ ）. A: i=1，j=4 B: i=4，j=1 C: i=4，j=9 D: i=9，j=4

下列程序段能且只能显示1！、2！、3！、4！的值的是（ ）。 A: For i = 1 To 4 n = 1 For j = 1 To i n = n * j Next j MsgBox(n)Next i B: For i = 1 To 4 For j = 1 To i n = 1 n = n * j Next j MsgBox(n)Next i C: n = 1For i = 1 To 4 For j = 1 To 4 n = n * j MsgBox(n) Next jNext i D: n = 1j = 1Do While j <= 4 n = n * j j = j + 1LoopMsgBox(n)

下列程序段能分别正确显示1!、2!、3!、4!的值的是______。 A: For i = 1 To 4 n = 1 For j = 1 To i n = n * j MsgBox(n) Next jNext i B: For i = 1 To 4 For j = 1 To i n = 1 n = n * j Next j MsgBox(n)Next i C: n = 1For i = 1 To 4 For j = 1 To 4 n = n * j MsgBox(n) Next jNext i D: n = 1j = 1Do While j &lt;= 4 n = n * j MsgBox(n) j = j + 1Loop

for(i=4;i>1;i--)for(j=1;j

以下程序段的输出结果是（）。inti,j;for(i=1;i<4;i++){for(j=1;j<4;j++)printf("%d*%d=%d",i,j,i*j);printf("\n");}

产生并输出如下形式的方阵。 1 2 2 2 2 2 1 3 1 2 2 2 1 4 3 3 1 2 1 4 4 3 3 3 1 4 4 4 3 3 1 5 1 4 4 3 1 5 5 5 1 4 1 5 5 5 5 5 1 #include "stdio.h" int main() { int a[7][7],i,j; for(i=0;i<7;i++) for(j=0;j<7;j++) if( (1) || i+j==6) a[i][j]=1; else if ( (2) &&i+j<6) a[i][j]=2; else if (i>j&&i+j<6) a[i][j]=3; else if (i i==j ; j==i
ii
i+j>6; j+i>6; 6

以下使i的运算结果为4的表达式是A.inti=0,j=0;(i＝3，(j十十)十i)；B.inti=1,j=0;j＝i＝((i=3)*2)；C..inti=0,j=1;(j＝＝1)?(i＝1)；(i＝3)；D.inti＝1，j＝1;i+＝j十＝2;

读以下程序，printf会被执行几次？__________#includeintmain(){inti,j;for(i=1;i<4;i++){for(j=i;j<4;j++)printf("%d*%d=%d",i,j,i*j);}}
