Problem: Given the temperature $T$ of the air and the wind speed $v,$ calculate the wind chill $T_{wc}$ : the temperature felt by

humans and animals in a cold wind.

$T_{wc}=35\mathrm{.}74+0\mathrm{.}6215T-35\mathrm{.}75v^{0\mathrm{.}16}+0\mathrm{.}4275T{v}^{0\mathrm{.}16}$

Temperatures and the wind speed are double precision.

The coefficients $(35\mathrm{.}74,0\mathrm{.}6215,-35\mathrm{.}75,0\mathrm{.}4275)$ and exponent $(0\mathrm{.}16)$ are required to be defined constants.

One mile is defined as $1\mathrm{.}609344$ kilometers. This is also a required defined constant.

The user can choose to enter either US customary units $($degrees Fahrenheit and miles per hour$)$ or SI units

$($degrees Celsius and kilometers per hour$).$ The program always displays the inputs in US units.

The equation above requires $T$ to be in degrees Fahrenheit and $v$ to be in miles per hour. The result $T_{wc}$ is the US

wind chill in degrees Fahrenheit. Convert the US wind chill to degrees Celsius for the SI wind chill.

Use $\frac{\frac{?}{?}}{302}\frac{\frac{?}{?}}{260}$ in your print $f$ format strings to display the degree symbol $().$

Use the $+$ flag for the temperature and wind chill placeholders in your print $f$ format strings to force a plus sign

to be displayed for positive numbers. See p$.58$ of the Forouzan & Gilberg textbook.

This assignment requires the implementation of the selection by calculation technique. See p$.51-52$ of the

course notes packet.
