Write a C++ program that will ask user to enter two integral numbers. The numbers should be swapped without using any third variable. Your code should be able to do the same process for 30 cycles. It should also show the swapped numbers at the each cycle. C++ Projects.

Code:

#include<iostream>
#include<conio.h>

using namespace std;
void main()
{
int a,b;
for(int i=1; i<=30; i++)
{
cout<<“\nCycle:”<<i<<endl;
cout<<“\nPlease Enter Any Numbers.\n”;
cout<<“Enter a Value a : “;
cin>>a;
cout<<“Enter a Value b : “;
cin>>b;
a=a+b;
b=a-b;
a=a-b;
cout<<“\nAfter Swapping These Two Numbers.\n”;
cout<<“Vale of a is: “<<a<<endl;
cout<<“Vale of b is: “<<b<<endl;
}
getch();
}

#include<iostream>
#include<conio.h>

using namespace std;
void main()
{
	int a,b;
	for(int i=1; i<=30; i++)
	{
		cout<<"\nCycle:"<<i<<endl;
		cout<<"\nPlease Enter Any Numbers.\n";
		cout<<"Enter a Value a : ";
		cin>>a;
		cout<<"Enter a Value b : ";
		cin>>b;
		a=a+b;
		b=a-b;
		a=a-b;
		cout<<"\nAfter Swapping These Two Numbers.\n";
		cout<<"Vale of a is: "<<a<<endl;
		cout<<"Vale of b is: "<<b<<endl;
	}
	getch();
}
