Write a program that will calculate a person's weekly gross pay $($gross pay is pay before taxes$).$ The program will ask the user to enter the pay rate $($as a double$),$ followed by the number of hours worked $($as a double$),$ and will display the weekly gross pay.

$(1)$ Ask the user for their pay rate $($$$/$hr$.).(1$ pt$)$

Enter the pay rate: $

$10\mathrm{.}00$

$(2)$ Ask the user for the number of hours worked. $(1$ pt$)$

Enter the pay rate: $

$10\mathrm{.}00$

Enter the number of hours worked:

$12\mathrm{.}0$

$(3)$ Multiplied the pay rate by the number of hours worked, and display the weekly gross pay. $(2$ pts$)$

Enter the pay rate: $

$10\mathrm{.}00$

Enter the number of hours worked:

$12\mathrm{.}0$

Pay: $$120\mathrm{.}00$

$(4)$ If the person works more than $40$ hours, they are paid "time$-$and$-$a$-$half" $(1\mathrm{.}5$x$)$ for hours in excess of $40$ hours. Have a decision to determine if the number of hours worked is in excess of $40,$ and if so$,$ calculate and display the weekly gross overtime pay. $(6$ pts$)$

You might want to create constants for the $40$ hours and for the "time $-$and$-$a$-$half" value of $1\mathrm{.}5.$
