 #include <iostream>  

using namespace std;  

int main()  

{  

int a=50, b=60;      

cout<<"Before swap a= "<<a<<" b= "<<b<<endl;      

a=a*b;        //a=50 (5*10)    

b=a/b;        //b=5 (50/10)    

a=a/b;        //a=10 (50/5)    

cout<<"After swap a= "<<a<<" b= "<<b<<endl;      

return 0;
