Make a program that take two integers and Swap their Values

#include <iostream>
using namespace std;
int main()
{
int a,b;
cout<<"Enter first Integer"<<endl;
cin>>a;
cout<<"Enterr second Integer"<<endl;
cin>>b;
a=a+b;
b=a-b;
a=a-b;
cout<<"Swapping of first integer is\n"<<a<<endl;
cout<<"Swapping of Second number is\n"<<b<<endl;
}
