How can values be swapped between 2 variables without using a temporary variable ?

IF A 9(2) has a value of 25 & B 9(2) has value of 50, at the end we shud have A as 50 & B as 25.

Hi,

Please find the logic

A=5 , B=2

A= A+B (A has value 7)

B= A-B (i.e 7-2=5 B has value 5)
A=A-B (Now 7-5 i.e A has 2)

Hope it helps..........

Regards
jai
