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
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
举一反三
- 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
- 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
- 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)
- 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 <= 4 n = n * j MsgBox(n) j = j + 1Loop
