s= 0
For i = 1 To 5
For j = 1 To i
For k = j To 4
s = s + 1
Next k
Next j
Next i
MsgBox s
A.4 B.5 C.38 D.40
自己算的和四个选项都不一样.

实际就是看s一共运行了多少次.这个并不难的.一共三层for语句,算出第三层for语句运行多少次就行了.
i=1时,j=1时s运行4次；
i=2,j=1,s运行4次；j=2,s运行3次；
i=3,j=1,s运行4；j=2,s运行3；j=3,s运行2
i=4,j=1,s运行4；j=2,s运行3；j=3,s运行2;j=4,s运行1
i=5,j=1,s运行4；j=2,s运行3；j=3,s运行2;j=4,s运行1;j=5,s运行0
4*5+3*4+2*3+1*2=20+12+6+2=40
所以选择D
