C++ and Java code can be automatically syntax-highlighted.

#include <iostream>


/** An example of some C++ code
*/

using namespace std;

int main() {
  cout << "Hello world!" << endl;
  return 0;
}

You can also apply various highlighting and other formatting to the code.

#include <iostream>


/** An example of some C++ code
*/

using namespace std;

int main() {
  cout << "Hello world!" << endl;
  return 0;
}

You can also place callouts in the code

#include <iostream>


/** An example of some C++ code
*/

using namespace std;

int main() {
  cout << "Hello world!" << endl;
  return 0;
}
