Constructors

Always try to provide a default constructor if possible.

Always try to initialize variables with their declaration.

C++

Delegating constructors is much faster than using assignment.

Foo(const unsigned int f, const bool b) : foo(f), bar(b) {}

Always follow the rule of three: if you include one of the following, you have to include all of them.

• Constructor

• Destructor

• Copy constructor

In virtual classes, always declare the destructor virtual.

Aggregate initialization for structs is great. Use them.

Not required, but declaring your constructor and destructor noexcept is good practice.

Java

When extending a class, always make sure to call super() unless the documentation explicitly tells you not to.
