C中的继承:如何向继承它的类隐藏“超类”属性

#include <stdio.h>

// 定义父类结构体
typedef struct {
    int superClassProperty;
} SuperClass;

// 定义子类结构体
typedef struct {
    SuperClass* superClass;
    int subClassProperty;
} SubClass;

// 父类方法
void superClassMethod(SuperClass* superClass) {
    printf("Super class method\n");
    printf("Super class property: %d\n", superClass->superClassProperty);
}

// 子类方法
void subClassMethod(SubClass* subClass) {
    printf("Sub class method\n");
    printf("Sub class property: %d\n", subClass->subClassProperty);
    superClassMethod(subClass->superClass);
}

int main() {
    // 创建父类对象
    SuperClass superClass;
    superClass.superClassProperty = 10;

    // 创建子类对象
    SubClass subClass;
    subClass.superClass = &superClass;
    subClass.subClassProperty = 20;

    // 调用子类方法
    subClassMethod(&subClass);

    return 0;
}
