Logic

Below is the logic of this program.

I have taken 3 variables for this program,"a,b and tem(or temporary).

According to logic,

Suppose the value of a is 10 and the value of b is 20.

According to the given condition,

tem=a;

tem=10;

a=b

10=b or b=10;

b=tem

20=tem

b=10.

So,after swapping,the value of "a" becomes 20 and the value of "b" becomes 10.
