Write a program in C++ to find the area of any triangle using Heron's Formula

Sample Output:

 Find the area of any triangle using Heron's Formula :                 
----------------------------------------------------------             
 Input the length of 1st side  of the triangle : 5                     
 Input the length of 2nd side  of the triangle : 5                     
 Input the length of 3rd side  of the triangle : 5                     
 The area of the triangle is : 10.8253

		cout << "----------------------------------------------------------\n";		
        cout<<" Input the length of 1st side  of the triangle : ";
    	cin>>side1;
        cout<<" Input the length of 2nd side  of the triangle : ";
    	cin>>side2;
        cout<<" Input the length of 3rd side  of the triangle : ";
    	cin>>side3;	
		s = (side1+side2+side3)/2;
		area = sqrt(s*(s-side1)*(s-side2)*(s-side3));
        cout<<" The area of the triangle is : "<< area << endl;
        cout << endl;
