假设有以下程序段：For i=1 to 3For j=5 to 1 Step -1Next jNext iPrint i,j则i、j的值分别是（ ）。
A: 4 0
B: 3 1
C: 4 1
D: 3 0
A: 4 0
B: 3 1
C: 4 1
D: 3 0
举一反三
- 假设有以下程序段： For i=1 to 3 For j=5 to 1 Step -1 Next j Next i Print i,j 则i、j的值分别是
- 下列程序段的执行结果为 。n = 0For i = 1 To 3 For j = 5 To 1 Step -1 n = n + 1Next j, iPrint n; j; i A: 12 0 4 B: 15 0 4 C: 12 3 1 D: 15 3 1
- 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
- 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
- 下列程序段的执行结果为 _______。 Dim a(3, 5) As Integer Dim i As Integer, j As Integer For i = 1 To 3 For j = 1 To 5 a(i, j) = a(i - 1, j - 1) + (i - 1) * 5 + j Next j Next i Print a(3, 4)
