### 插入程序代码 ###

传统一点， `\usepackage{listings}`, 详情可以使用`texdoc listings`查看。

\lstset{language=C}
    \begin{lstlisting}
    #include <iostream>
    using namespace std;
    
    int main()
    {
        cout<<"hello"<<endl;
        return 0;
    }
    \end{lstlisting}

对效果进行一些定制：

\usepackage{ listings}
    \usepackage{ xcolor}
    \lstset{ 
        numbers=left, 
        numberstyle= \tiny, 
        keywordstyle= \color{  blue!70},
        commentstyle= \color{ red!50!green!50!blue!50}, 
        frame=shadowbox, % 阴影效果
        rulesepcolor= \color{  red!20!green!20!blue!20} ,
        escapeinside=``, % 英文分号中可写入中文
        xleftmargin=2em,xrightmargin=2em, aboveskip=1em,
        framexleftmargin=2em
    }

效果：

#### mac 定制代码字体 ####

%!TEX program = xelatex
    \documentclass{ article}
    \usepackage{ listings}
    \usepackage{ fontspec} % 定制字体
    \newfontfamily\menlo{ Menlo}
    \usepackage{ xcolor} % 定制颜色
    \definecolor{ mygreen}{ rgb}{ 0,0.6,0}
    \definecolor{ mygray}{ rgb}{ 0.5,0.5,0.5}
    \definecolor{ mymauve}{ rgb}{ 0.58,0,0.82}
    \lstset{  %
    backgroundcolor=\color{ white},      % choose the background color
    basicstyle=\footnotesize\ttfamily,  % size of fonts used for the code
    columns=fullflexible,
    tabsize=4,
    breaklines=true,               % automatic line breaking only at whitespace
    captionpos=b,                  % sets the caption-position to bottom
    commentstyle=\color{ mygreen},  % comment style
    escapeinside={ \%*}{ *)},        % if you want to add LaTeX within your code
    keywordstyle=\color{ blue},     % keyword style
    stringstyle=\color{ mymauve}\ttfamily,  % string literal style
    frame=single,
    rulesepcolor=\color{ red!20!green!20!blue!20},
    % identifierstyle=\color{red},
    language=c++,
    }
    \begin{ document}
    \begin{ lstlisting}[language={ [ANSI]C},
            numbers=left,
            numberstyle=\tiny\menlo,
            basicstyle=\small\menlo]
    #include <stdio.h>
    #include <stdbool.h>
    #include <ctype.h>
    
    #define SIZE 26
    
    int
    main (int argc, char *argv[])
    { 
      int array[SIZE];
      int i;
      char c;
    
      for (i = 0; i < SIZE; i++)
        array[i] = 0;
    
      while ((c = getchar ()) != EOF)
        { 
          if (isupper (c))
            { 
              array[c - 'A']++;
            }
        }
      for (i = 0; i < 26; i++)
        printf ("%c:%5d\n", (char) ('A' + i), array[i]);
    
      return 0;
    }
    \end{ lstlisting}
    \end{ document}
    % Local Variables:
    % TeX-engine: xetex
    % End:
