C$++$ A pedometer treats walking $2,000$ steps as walking $1$ mile. Write a StepsToMiles$()$ function that takes the number of steps as an integer parameter and returns the miles walked as a double. The StepsToMiles$()$ function throws a runtime$\_$error object with the message "Exception: Negative step count entered." when the number of steps is negative. Complete the main$()$ function that reads the number of steps from a user, calls the StepsToMiles$()$ function, and outputs the returned value from the StepsToMiles$()$ function. Use a try$-$catch block to catch any runtime$\_$error object thrown by the StepsToMiles$()$ function and output the exception message.

Output each floating$-$point value with two digits after the decimal point, which can be achieved by executing

cout $<<$ fixed $<<$ setprecision$(2)$; once before all other cout statements.

Ex: If the input of the program is:

$5345$

the output of the program is:

$2\mathrm{.}67$

Ex: If the input of the program is:

$-3850$

the output of the program is:

Exception: Negative step count entered.
