/*costructor is a particular data type which is used to group a couple of objectes for various time. 
if the valaueis not given here then by default it takes garbage value. 
and inside a constructor the passing value will be printed for that iteration.*/

//FIRST STEP:


/*
class laptop
{
public:
	string name;

//the value can also be passed as laptop(objname= " Mac", objprice = 100.00)

//SECOND STEP:
