display code block using html

In the following example we use CSS properties with samp tag to display C++ computer code.

Code:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Display computer code</title>
<style type="text/css">
samp.code{
  background: #EEE;
  border: 2px groove red;
  color: #111;
  padding: 6px;
  width: 300px;
  display: block;
}

</style>
</head>

<body>
<p><samp class="code">
      std::vector<std::vector<double> > rawdata(3);<br/>
    int datapts = readdata_NxM(argv[4], rawdata);<br/>
    if (datapts <= 0) {<br/>
        std::cerr << "Error reading data from file \n" << argv[4] << std::endl;<br/>
        usage(argv[0]);<br/>
    }<br/>
<br/>
    // convert from Nx3 matrix to individual vectors. Not very elegant...<br/>
    double* xpos = &rawdata[0][0];<br/>
    double* ypos = &rawdata[1][0];<br/>
    double* clst = &rawdata[2][0];<br/>
    double* weights = &weightdata[0][0];<br/>

<br/>
</samp></p>

</body>
</html>
