Write a function called read$\_$vector which inputs from the user a $2$D vector by reading its x$-$ and y$-$ coordinates. If the user enters zero for BOTH coordinates then repeatedly display the message "Coordinates cannot both be zero." and re$-$prompt the user. Use the global constant EPSILON to compare these values to zero. Define the function so that it does not return a value and has three input parameters:

Type string that holds the prompt displayed to the user. Define the string as a const parameter and use pass$-$by$-$reference. See the lecture notes on how to do this.

Type double that holds the first coordinate of the $2$D vector. Define this parameter as pass$-$by$-$reference.

Type double that holds the second coordinate of the $2$D vector. Define this parameter as pass$-$by$-$reference.
