This PHP example program demonstrates how to color comments with regular expressions.
<?php // Code to load the program file and style the comments $sCppProgramFileName = "main.cpp"; $saCppProgramFile = file($sCppProgramFileName); $sCppProgram = ""; $bInsideComment = false; foreach($saCppProgramFile as $sNextLine) { // Check for three typs of comments; start, end, and to the end of the line. $sNextLine = htmlspecialchars($sNextLine, ENT_QUOTES | ENT_HTML5); $sNextLine = str_replace('$', '$', $sNextLine); $sNextLine = preg_replace('/\/\*/', '<span class="comments">/*', $sNextLine); $sNextLine = preg_replace('/\*\//', '*/</span>', $sNextLine); $sNextLine = preg_replace('/\/\/(.*)(\r\n)/', '<span class="comments">//\1</span>\2', $sNextLine); $sCppProgram .= $sNextLine; } echo "<!DOCTYPE html><html>"; echo "<head> <style type=\"text/css\"> .comments { color: Red; } </style>"; echo "</head>"; echo "<body>"; echo "<pre>".$sCppProgram."</pre>"; echo "</body>"; echo "</html>"; ?>
#include <iostream> #include <fstream> int main() { std::cout << "Writing to the file . . ." << std::endl; // We will create an output file stream so that we can open it for writing. std::ofstream qTextFile; // Create a new file or write over an old one. qTextFile.open("Virtues.txt"); /* Write the four cardinal virtues to it.*/ qTextFile << "Fortitude" << std::endl; qTextFile << "Prudence" << std::endl; qTextFile << "Justice" << std::endl; qTextFile << "Temperance" << std::endl; qTextFile.close(); return 0; }
