The Chat$-$A$-$While phone company provides service to six area codes and charges the per$-$minute rates for phone calls shown in Figure $6-25($below$).$

Write a program named ChatAWhile that stores the area codes and rates in parallel arrays and allows a user to enter an area code and the length of time for a call in minutes, and then display the total cost of the call.

For example if the area code is in the array, such as $715,$ and the call length is $22$ minutes, the output should be:

Your phone call to area $715$ costs $$0\mathrm{.}16$ per minute

For $22$ minutes the total is $$3\mathrm{.}52$

If the area code is not in the array, such as $111,$ the program should not accept a call length, and instead output Sorry $-$ no calls allowed to area $111.$
