是由線性 congruential 演算法產生隨機序列。

template<class UIntType,
    UIntType A, UIntType C, UIntType M>
    class linear_congruential_engine {
public:
    typedef UIntType result_type;
    static const UIntType multiplier = A;
    static const UIntType increment = C;
    static const UIntType modulus = M;
    static const UIntType default_seed = 1U;
    explicit linear_congruential_engine(result_type x0 = default_seed);
    explicit linear_congruential_engine(seed_seq& seq);
    void seed(result_type x0 = default_seed);
    void seed(seed_seq& seq);
    static const result_type min();
    static const result_type max();
    result_type operator()();
    void discard(unsigned long long count)();
private:
    result_type stored_value;
    };
