Answer / venki
x=10 and y=20
x=x+y

=>x=30
y=x-y
=>y=30-20=10
=>y=10 ----->@1
x=x-y
=>x=30-10=20

Answer / sandip patil
If X=10 & Y=20
then for swapping just go with following
Y=Y-X i.e. Y=20-10=10 here value of Y=10
X=X+Y i.e. X=10+10=20 Here value of X=20
It is swap

'a and b are two variables ; Following code swaps both number and string inputs
a = Inputbox("Enter a")
b = Inputbox("Enter b")
a = a + b
b = left(a,(instr(a,b)-1))
a = Right(a,(len(a)-len(b)))
msgbox "b ="&b
msgbox "a = "&a
