Question

建立名为CStudent的类，该类有成员变量：姓名、学号、数学、语文、英语三门课成绩

还包括两个成员函数：用于初始化学生姓名、学号、性别和三门课成绩的构造函数；用于输出学生信息的函数。编写主函数，并声明一个CStudent对象，然后调用成员函数在屏幕输出对象信息。

Answer 1

#include <iostream>
#include <string>
#include <memory.h>

using std::string;
using std::cout;
using std::endl;

class CStudent
{
public:
CStudent(){}
CStudent(string name, unsigned int id, bool Isman, float score[3]);
~CStudent(){}

void PrintInfo(); // 输出学生信息.

protected:
private:
string m_name;
unsigned int m_id;
bool m_Isman;
float m_score[3];
};

CStudent::CStudent(string name, unsigned int id, bool Isman, float score[3])
{
m_name = name;
m_id = id;
m_Isman = Isman;
memcpy(m_score, score, 3 * sizeof(float));
}

void CStudent::PrintInfo()
{
cout<<"姓名:"<<m_name
<<", 学号:"<<m_id;
m_Isman ? (cout<<", 男性") : (cout<<", 女性");
cout<<", 成绩:"<<m_score[0]<<" "<<m_score[1]<<" "<<m_score[2]<<endl;

}

int main(void)
{
string name("张三");
unsigned int id(210);
bool man = true; // 是爷们
float score[3] = {80, 90, 99};
CStudent student(name, id, man, score);
student.PrintInfo();

return 0;
}
