LaTex(PART XIX)插入代码并且高亮显示

需要的包：

\usepackage{listings}%插入代码
\usepackage{xcolor}%定义各种颜色

用法：

    \begin{lstlisting}[language]

    \end{lstlisting}

示例代码：

\documentclass[UTF8]{ctexart}
\usepackage{listings}
\usepackage{xcolor}
\lstset{
    backgroundcolor=\color{red!50!green!50!blue!50},%代码块背景色为浅灰色
    rulesepcolor= \color{gray}, %代码块边框颜色
    breaklines=true,  %代码过长则换行
    numbers=left, %行号在左侧显示
    numberstyle= \small,%行号字体
    keywordstyle= \color{red},%关键字颜色
    commentstyle=\color{green}, %注释颜色
    frame=shadowbox%用方框框住代码块
    } 

\begin{document}
	%this is a fragment of java code
	\begin{lstlisting}[language={java}]
	//java code
	public class Main{
		public static void main(String[]args){
			System.out.println("hello,world");
		}
	}
	\end{lstlisting}
	%this is a fragment of c code
	\begin{lstlisting}[language={c}]
	//C code
	#include
	int main(){
	 printf("hello,world");
	 return 0;
	}
	\end{lstlisting}
\end{document}
