Before doing example, You have to configure cgi-bin with apache server.
If its done then try your first example.
Open an empty file and write following c++ code.
#include <iostream>
using namespace std;
int main ()
{
cout << "Content-type:text/html\n\n";
cout << "Hello World - First CGI Program";
return 0;
}
Now save this file with .cpp extension(example.cpp) in public_html/cgi-bin folder.
Then compile that program.
$ g++ -o example example.cpp
This will create example file which is executable.
Then open browser and open following link”
localhost/~username/cgi-bin/example
This will show you following o/p on browser.
Hello World – First CGI Program
If you find any problem then share it as comments.
Thankyou.
