我想寫一個(gè)基于Java代碼的c++1z程序首先在Java中聲明一個(gè)接口。public interface MyExpression {  public boolean interpret();}java中實(shí)現(xiàn)接口的抽象類public abstract class NonTerminal implements MyExpression {  protected MyExpression left, right;  public void setLeft(MyExpression left) {    this.left = left;  }  public void setRight(MyExpression right) {    this.right = right;  }}最后是班級(jí)public class Or extends NonTerminal {  public boolean interpret() {    return left.interpret() || right.interpret();  }  public String toString() {    return String.format("(%s | %s)", left, right);  }}如何在現(xiàn)代 C++ 中創(chuàng)建此功能？更新 C++ 代碼片段#include <iostream>#include <memory>#include <ostream>class BooleanExpression {public:    virtual ~BooleanExpression() = default;    virtual bool interpret() = 0;};class NonTerminal : public BooleanExpression {protected:    std::unique_ptr<BooleanExpression> left, right;public:    void setLeft(std::unique_ptr<BooleanExpression>&& left) {        this->left = std::move(left);    }    void setRight(std::unique_ptr<BooleanExpression>&& right) {        this->right = std::move(right);    }};class Terminal : public BooleanExpression {protected:    bool value;public:    Terminal(bool value) : value(value) {}    //tostring};class False : public Terminal {public:    False() : Terminal(false) {}    //tostring};class True : public Terminal {public:    True() : Terminal(true) {}    //tostring};class Or : public NonTerminal {public:    bool interpret() {        return left->interpret() || right->interpret();    }};class And : public NonTerminal {public:    bool interpret() {        return left->interpret() && right->interpret();    }    //tostring};int main() {    using namespace std;    auto  t1 = make_unique<True>();    auto f1 = make_unique<False>();    auto or1 = make_unique<Or>();    or1->setLeft(t1);    return 0;}這段代碼無法編譯。or1->setLeft不接受t1，即make_unique()。
