User is required to input 2 numbers then program will check their equality.



In this example we will make a program which will tell if 2 numbers are equal , smaller or greater .
thats all and we are also going to use while loop so that program don't terminate by itself.

Here are Screenshots of my program below.









and heres the code.
Just copy and paste it in the visual studio code input box



#include <iostream>
using namespace std;
int main()
{
	int m;
	int n;

	cout<<"        \n\n  Enter first number : ";
	cin>>m;
	cout<<"        \n\n  Enter second number : ";
	cin>>n;
while(m)
{
while(m==n)
{
	if(m==n)
	{
		cout<<"  \n\n  Both numbers are equal  \n\n";
	}

	cout<<"        \n\n  Enter first number : ";
	cin>>m;
	cout<<"        \n\n  Enter second number : ";
	cin>>n;

}
	while(m!=n)
	{
		if(m>n)
{
	cout<<"        \n\n  First number is greater than second      \n\n  ";
		}
		if(m<n)
		{
			cout<<"        \n\n  Second number is greater than first       \n\n ";
		}


		cout<<"        \n\n  Enter first number : ";
	cin>>m;
	cout<<"        \n\n  Enter second number : ";
	cin>>n;

	}
}
	return 0;
}
