Javascript syntax highlighting

Page author does not have to prettify code.
Just include it on page and this Javascript program syntax-highlights it at runtime.

From here.

C++ code

#include <stdio.h>
#include <stdlib.h>  

// comment

main ( int argc, char **argv )
{
 double lamb = atof ( argv[1] );
 double x = atof ( argv[2] );   

 for ( int i=1; i<=30; i++ ) 
 {
   printf( "%.5f \n", x );
   x = lamb * x * (1-x);
 }           
}
