CGI using C++

The Common Gateway Interface (CGI) is a standard protocol for enabling applications (called CGI programs or CGI scripts) to interact with Web servers and with clients. These CGI programs can be a written in Python, PERL, Shell, C or C++ etc.

make sure that your Web Server supports CGI and it is configured to handle CGI Programs. All the CGI Programs to be executed by the HTTP server are kept in a pre-configured directory. This directory is called CGI directory and by convention it is named as /var/www/cgi-bin. By convention CGI files will have extension as .cgi, though they are C++ executable.

By default, Apache Web Server is configured to run CGI programs in /var/www/cgi-bin. 


#include <iostream>
using namespace std;
 
int main ()
{
    
   cout << "Content-type:text/html\r\n\r\n";
   cout << "<html>\n";
   cout << "<head>\n";
   cout << "<title>Hello World - First CGI Program</title>\n";
   cout << "</head>\n";
   cout << "<body>\n";
   cout << "<h2>Hello World! This is my first CGI program</h2>\n";
   cout << "</body>\n";
   cout << "</html>\n";
   
   return 0;
}


Compile above code and name the executable as cplusplus.cgi. This file is being kept in /var/www/cgi-bin directory and it has following content. Before running your CGI program make sure you have change mode of file using chmod 755 cplusplus.cgi UNIX command to make file executable.

Write then read a text file

This C# code snippet writes a text file from an internal string then reads it back using StreamReader, StreamWriter, TextReader, and TextWriter. 
using System;
using System.IO;
 
public class WriteReadClass
{
   public static void Main()
   {
      // write a text file
      TextWriter tws = new StreamWriter ("test.txt");
    
      // write the current datetime to the stream
      tws.WriteLine (DateTime.Now);
    
      // write test strings to the stream
      tws.Write (" Test string 1 to write to file.\n");
      tws.Write (" Test string 2 to write to file.\n");
    
      tws.Close();   // close the stream
 
      // now, read in the text file
      TextReader trs = new StreamReader ("test.txt");
    
      // read the first line of text 
      Console.WriteLine (trs.ReadLine());
 
      // read the rest of the text lines
      Console.WriteLine (trs.ReadToEnd());
    
      trs.Close();   // close the stream
 
      Console.Write ("\nPress \"Enter\" to exit ...");
      Console.Read();
   }
}
