6. You are developing a program to control the warning signs as theexists of major tunnels. If roads are slick ( road_status is S) , youwant to advise drives that stopping times are doubled or quadrupled ,depending on whether the road are wet or icy. Your program willalso have access to the current temperature in degrees Celsius (temp),


6

so a check as to whether the temperature is above or below freezingwould allow you to choose the correct message. If the road wet youwill tell the drivers and tell him that stopping time is doubled. If the

road is icy tell the drivers that and the stopping time is quadruple.Otherwise tell him to Drive carefully

24 or 32 If the number is divisible by 5 and divisible by 3 then

display you enter a number divisible by 3 and 5.Else print on screen not divisible by 3 and 5

b) And if the number is less than or equal to 20 then printnumber to screen.
