Parameter settings in listing?

Question

How to modify the font of the code in the listing. I tried basicstyle = \sffamily and it didn't seem to work. Now I can change the font type. But How to modify the spacing between codes. For example, 1.5 times the line spacing.

The code is:

\begin{listing}
    \noindent
    \begin{minipage}[b]{0.5\textwidth}
        \begin{framed}
            \begin{lstlisting}[gobble=16, language=C,numbers=left,numberstyle={\color{numbercolor}\normalfont},
            numbersep={-0.5cm},keywordstyle={\color{keywordcolor}},basicstyle = \sffamily]
            if (secret)
                access line 0
            else
                access line 1
            \end{lstlisting}
            \captionof{subfigure}{Victim function}
        \end{framed}
    \end{minipage}%
    \\[-0.15em]
    \begin{minipage}[b]{0.5\textwidth}
        \begin{framed}
            \begin{lstlisting}[gobble=16, language=C,numbers=left,numberstyle={\color{numbercolor}\normalfont},
        numbersep={-0.5cm},keywordstyle={\color{keywordcolor}}]
            if (secret)
                access line 0
            else
                access line 1
            \end{lstlisting}
            \captionof{subfigure}{Victim function}
        \end{framed}
    \end{minipage}
    \caption{subfigure}{Victim function}
\end{listing}

The result is :

But what I want is:
