Visual Basic程序问题
与程序段:
a = a + b
b = a - b
a = a - b
功能相同的程序段是
A.a = b
b = a
B.a = a + b
a = a - b
b = a - b
C.t = a
a = b
b = t
D.If a > b Then
a = b
Else
b = a
End If
答案是C,为什么呢?

Visual Basic程序问题与程序段:a = a + bb = a - ba = a - b功能相同的程序段是A.a = bb = aB.a = a + ba = a - bb = a - bC.t = aa = bb = tD.If a > b Thena = bElseb = aEnd If答案是C,为什么呢?
就是把值换一下.

a=10
b=5
a = a + b '10+5=15
b = a - b '15-5=10 b=10
a = a - b '15-10=5 a=5
答案C也是这个效果.

有如下Visual Basic程序段: m = a(1) i = 2 Do While i Visual Basic程序问题与程序段:a = a + bb = a - ba = a - b功能相同的程序段是A.a = bb = aB.a = a + ba = a - bb = a - bC.t = aa = bb = tD.If a > b Thena = bElseb = aEnd If答案是C,为什么呢? 下列Visual Basic程序段运行后,变量min的结果为():A=10 :b=5 :min=aIf b 下列Visual Basic程序段中,能实现输出变量a、b、c三个数中最大数的是( ) VB习题没看懂~VB习题:执行以下程序段后,c$的值为()a$=Visual basicb$=GoodC$=b$&UCase(Mid$(a$,8,1))&Right$(a$,4)A.Visual BASIC B.Good Basic C.GOOD Basic D.Good BASIC为什么选择B呢? 在Visual Basic中,与程序段:a = a + bb = a - ba = a - b功能相同的程序段是A. a = b  b = aB. a = a + b  a = a - b  b = a - bC.t = aa = bb = tD.
