派生类调用基类构造函数```#include using namespace std; //基类People class

using namespace std;
//基类People
class People {
protected:
	char *m_name;
	int m_age;
public:
	People(char*, int);
};
People::People(char *name, int age) : m_name(name), m_age(age) {}
//派生类Student
class Student : public People {
private:
	float m_score;
public:
	Student(char *name, int age, float score);
	void display();
};
//People(name, age)就是调用基类的构造函数
Student::Student(char *name, int age, float score) : People(name, age), m_score(score) { }
void Student::display() {
	cout << m_name << "的年龄是" << m_age << "，成绩是" << m_score << "。" << endl;
}
int main() {
	Student stu("小明", 16, 90.5);
	stu.display();
	return 0;
}
