使用类/结构的不同方法 - C++

class MyClass {
public:
    void set_value(int value) { this->value = value; }
    int get_value() { return value; }
private:
    int value;
};

struct MyStruct {
    void set_value(int value) { this->value = value; }
    int get_value() { return value; }
    int value;
};

class DerivedClass : public BaseClass {
    // ...
};

struct DerivedStruct : BaseStruct {
    // ...
};

template<typename T>
class MyClass {
    T value;
public:
    void set_value(T value) { this->value = value; }
    T get_value() { return value; }
};

template<typename T>
struct MyStruct {
    T value;
    void set_value(T value) { this->value = value; }
    T get_value() { return value; }
};

class MyClass {
public:
    MyClass(int value) : value(value) {}
private:
    int value;
};

struct MyStruct {
    int value;
};

int main() {
    MyClass obj1(10);
    MyStruct obj2 = {10};
}
