One yard equals $36$ inches. The following program intends to read a floating$-$point value from input, convert the value from inches to yards, and output the length in yards, but the code contains errors. Find and fix the errors.

Ex: If the input is $3\mathrm{.}1,$ then the output is:

$0\mathrm{.}086$ yards

using namespace std;

int main$()\{$

$//$ Modify the following code

int lengthInches;

int lengthYards;

cin $$ lengthInches;

lengthYards $=$ lengthInches $\frac{?}{36}$;

cout $$ fixed $$ setprecision$(3)$ lengthYards yards" $$ endl;

return $$;
