VB中 逻辑表达式 怎么表示

1:X+Y小于10 且 X-Y要大于0
2:X.Y都是正整数或都是负整数
3:A.B之一为零但不得同时为零
4:C1+C2+C3大于等于255或C1与C2分别大于90且C3大于80

Answer 1

1:X+Y小于10 且 X-Y要大于0 ----------------------------
X+Y<10 and X-Y>0
2:X.Y都是正整数或都是负整数 --------------------------
int(X)=X and int(Y)=y and (sng(X)=sng(Y))
3:A.B之一为零但不得同时为零 --------------------------
(A=0 or B=0)and A<>B
4:C1+C2+C3大于等于255或C1与C2分别大于90且C3大于80 ----
C1+C2+C3>=255 or ((C1>90 or C2>90) and C3>80)

Answer 2

1
x+y<10 and x-y>0

2
x=Cint(x)
y=Cint(y)
x*y>0

3
(a=0 or b=0) and a<>b

4
(c1+c2+c3>=255) or (c1>90 and c2>90 and c3>80)
