如何将不同的模板类型放入一个向量中

#include<iostream>
#include<vector>

// 定义基类模板
template<typename T>
class Element {
public:
    virtual void print() = 0;
};

// 定义特化的子类
template<typename T>
class ElementImpl : public Element<T> {
public:
    ElementImpl(const T& value) : m_value(value) {}
    virtual void print() {
        std::cout << m_value<< std::endl;
    }
private:
    T m_value;
};

// 定义向量类型
typedef std::vector<Element<int>*> Vector;

int main() {
    // 将不同的模板类型放入向量中
    Vector vec;
    vec.push_back(new ElementImpl<int>(10));
    vec.push_back(new ElementImpl<float>(3.14));
    vec.push_back(new ElementImpl<double>(2.718));

    // 遍历向量并打印元素
    for (Vector::iterator it = vec.begin(); it != vec.end(); ++it) {
        (*it)->print();
    }

    // 释放内存
    for (Vector::iterator it = vec.begin(); it != vec.end(); ++it) {
        delete *it;
    }

    return 0;
}
