假定有以下程序段： n=0 for i=1 to 4 for j=3 to -1 step -1 n=n+l next j next i运行完毕后n的值是( )。
A: 12
B: 15
C: 16
D: 20
A: 12
B: 15
C: 16
D: 20
举一反三
- 假定有以下程序段 n = 0 For i = 1 To 3 For j = -4 To -1 n = n + 1 Next j Next i 运行完毕后，n的值是
- 假定有以下程序段n=0for i=1 to 6 step 2 for j=4 to 1 step -1 n=n+1 next jnext i运行完毕后，n的值是______。 A: 0 B: 3 C: 4 D: 12
- 执行下列程序段后，输出结果是 n = 0 For i=1 To 3 For j=5 To 1 Step -1 n = n + 1 Next j, i Debug.Print n; j; i
- 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)
