Create a user$-$defined data structure $($i$.$e$.,$ struct$)$ called CartesianCoordinate that represents a two$-$dimensional Cartesian coordinate $($x$,$ y$).$ The member variables of this struct will be just x and y$,$ which are both floating$-$point values.

$(5$ points$)$ Define a function called calculateDistance that takes two parameters, each of type CartesianCoordinate$*($i$.$e$.,$ pointer to CartesianCoordinate$)$ and returns the distance between the two given CartesianCoordinate points. As you may recall, the formula for calculating the distance between two CartesianCoordinate points, say p$1($x$1,$ y$1)$ and p$2($x$2,$ y$2)$ is:
