One gallon equals $16$ cups. The following program intends to read a floating$-$point value from input, convert the value from cups to gallons, and output the volume in gallons, but the code contains an error. Find and fix the error.

Ex: If the input is $2\mathrm{.}5,$ then the output is:

$0\mathrm{.}156$ gallons

$12345$

# Modify the following codevol$\_$cups $=$ int$($input$())$vol$\_$gallons $=$ vol$\_$cups $/16$print$($f$\text{'}\{$vol$\_$gallons:$\mathrm{.}3$f$\}$ gallons'$)$
