you are required to use class templates to create a class that can work with different data types. The task demonstrates how templates help achieve generic programming in C++. Khelo24bet Register

Answer

template<class T>
class AddElements {
public :
    AddElements(T element1) {
        m_element1 = element1;
    }
    T add(T element2) {
        m_element2 = m_element1 + element2;
        return m_element2;
    }
    T concatenate(T element2) {
        m_element2 = m_element1 + element2;
        return m_element2;
    }
    T m_element1;
    T m_element2;
};

using namespace std; template class AddElements { T element; public: AddElements(T arg) : element(arg) {} T add(T arg) { return element + arg; } }; template <> class AddElements { string element; public: AddElements(const string &arg) : element(arg) {} string concatenate(const string &arg) { return element + arg; } };

int main() { ios::sync_with_stdio(false); cin.tie(nullptr); int n; cin >> n;

string type;
for (int i = 0; i < n; ++i) {
    cin >> type;

    if (type == "int") {
        int a, b;
        cin >> a >> b;
        AddElements<int> myint(a);
        cout << myint.add(b) << '\n';
    } 
    else if (type == "float") {
        double a, b;
        cin >> a >> b;
        AddElements<double> myfloat(a);
        cout << myfloat.add(b) << '\n';
    } 
    else if (type == "string") {
        string a, b;
        cin >> a >> b;
        AddElements<string> mystring(a);
        cout << mystring.concatenate(b) << '\n';
    }
}

return 0;

}

/Write the class AddElements here/ template class AddElements { T element; public: AddElements(T arg) : element(arg) {} T add(const T& other) { return element + other; } };

// specialization for string: use concatenate() template <> class AddElements { string element; public: AddElements(string arg) : element(std::move(arg)) {} string concatenate(const string& other) { return element + other; } };

C++ class templates are such a powerful feature! 🌟 They make code reusable and type-safe, which is perfect for solving a variety of problems efficiently. Mahadev Book Login ID and Password
