			cout<<"\n\tEnter a: "; cin>>a;
			cout<<"\n\tEnter b: "; cin>>b;
		}
		if(Flag==1)
		{
			cout<<"\n\t"<<a<<" + "<<b<<" = "<<a+b;
		}
		if(Flag==2)
		{
			cout<<"\n\t"<<a<<" - "<<b<<" = "<<a-b;
		}
		if(Flag==3)
		{
			cout<<"\n\t"<<a<<" * "<<b<<" = "<<a*b;
		}
		if(Flag==4)
		{
			cout<<"\n\t"<<a<<" / "<<b<<" = "<<a/b;
