Input B
Print "Enter C: ";
Input C

M = A
If M < B Then M = B
If M < C Then M = C
Print M

Answer 2

Dim A As Integer
Dim B As Integer
Dim C As Integer
Dim M As Integer

A = 100
B = 9
C = 1000

M = A '假设 A 是最大的...
If M < B Then M = B
If M < C Then M = C
Print M

Answer 3

if A<B then A=B
if A<C then A=C
然后A就是最大的数
