Create a new file named convert.cpp$.$ In this file, write a program that asks the user for a temperature, then converts that temperature to four $($semi$-)$common temperature units.

The prompt should be Enter a temperature: $($followed by a newline$),$ and the user will enter a number, followed by a space, followed by a capital letter. The letter specifies a unit. Supported units are as follows, and the results should always print in this order, with exactly two digits after the decimal point:

C for Celsius

F for Fahrenheit

K for Kelvin

R for Rankine

$[$alice@wonderland lab$2]$$ $./$convert

Enter a temperature:

$98\mathrm{.}6$ F

$=37\mathrm{.}00$ C

$=98\mathrm{.}60$ F

$=310\mathrm{.}15$ K

$=558\mathrm{.}27$ R

To ensure the correct number of decimal digits, include the iomanip header and add the following line before printing your results $($C$++$ has annoyingly quirky output formatting commands$)$:

std::cout $<<$ std::fixed $<<$ std::setprecision$(2)$;
