}

/*…Main Function End’s…*/
//the above program adds 2 distance (objects) length1 and length2 to produce
//third distance(object)total.
//the function sum() takes an object of distance type as argument and returns
//an object of distance type containing sum of the passed object and the
//current object through which sum() function is invoked.

/*…The output is something like this…*/::::::::
