$\}$ Four doubles are read from input, where the first two doubles are the kilograms and grams of mass$1$ and the second two doubles are the kilograms and grams of mass$2.$ Define two functions to overload the $+$ operator. The first function overloads the $+$ operator to add two masses. The second function overloads the $+$ operator to add a mass and a double representing the number of kilograms.

Ex: If the input is $9\mathrm{.}0369\mathrm{.}54\mathrm{.}02\mathrm{.}5,$ then the output is:

$9$ kilograms, $369\mathrm{.}5$ grams

$4$ kilograms, $2\mathrm{.}5$ grams

Sum: $13$ kilograms, $372$ grams

$9$ kilograms, $369\mathrm{.}5$ grams

$4$ kilograms

Sum: $13$ kilograms, $369\mathrm{.}5$ grams

Note: The sum of two masses is:

the sum of the number of kilograms

the sum of the number of grams

Note: The sum of a mass and a double representing the number of kilograms is:

the sum of the number of kilograms and the double

the number of grams is unchanged $603602\mathrm{.}4281174.q3zqy7$
