# readability-deleted-default

Checks that constructors and assignment operators marked as `= default` are not actually deleted by the compiler.

    class Example {
    public:
      // This constructor is deleted because I is missing a default value.
      Example() = default;
      // This is fine.
      Example(const Example& Other) = default;
      // This operator is deleted because I cannot be assigned (it is const).
      Example& operator=(const Example& Other) = default;

    private:
      const int I;
    };
