vb简单计算for a =1 to 2 for b =1 to a for c = b to 2 i=i+1 next vb多重循环试题For i= 1 to 3 for j= 1to i for k= j to 3 a=a+1 next vb for a=0 for i=1 to 10 a=a+1 b=0 for j=1 to 10 a=a+1 b=b+2 For i = 1 To 4 For j = 1 To 5 b(i) = b(i) + a(i,j) Next j Ne VB语言:for i=a to b steo c a可以大于b 吗?c可以为负数么? 下列程序的执行结果为（）.dim a(10),b(5) for i=1 to 10 a(i)=i next i for vb题,For i=1 to 2 for j=1 to 2 for k=1 to j vb读程序题：For i=1 to 3 For j=1 to i For k=j to 3 a=a+1 Next k,j Dim x(100), a For i = 1 To 100 x(i) = i Next i For Each a In vb中for语句 用*画几何图形.For B = 1 To i - 1 还有就是怎么编个正方形 读下面程序：for i=1 to 3 for j=i to1 for k=j to 3 a=a+1 next k nex VB step1 还有for i=1 to 10 step
