Chapter 6. Contributions Guide
Spacing
• Don’t indent inside namespaces.
• Put public, protected and private labels at the same indentation level as the corresponding class
label.
Simple Example
// file spaceship.h
#ifndef SPACESHIP_H_
#define SPACESHIP_H_
#include <cstdlib>
namespace spaceships {
class SpaceShip {
public:
SpaceShip(size_t crew);
size_t get_crew_size() const;
private:
const size_t crew;
};
class SpaceShuttle : public SpaceShip {
public:
SpaceShuttle();
};
class Sojuz : public SpaceShip {
public:
Sojuz();
};
template <typename T>
class CargoShip {
public:
CargoShip(const T &cargo);
private:
T cargo;
};
} // namespace spaceships
#endif // SPACESHIP_H_
// file spaceship.cpp
#include "spaceship.h"
namespace spaceships {
// Putting the curly braces in the same line for constructors is OK if it only␣
,→initializes
// values in the initializer list
SpaceShip::SpaceShip(size_t crew) : crew(crew) { }
size_t SpaceShip::get_crew_size() const
{
return crew;
}
