?把struct结构体改成calss类

#include <iostream>
 
class u
{
public:
    int score;
private:
    int age;
    char sex;
    float high;
public:
    void set_msg(int a,char sex,float high);
    int get_age();
    char get_sex();
    float get_high();
};
using namespace std;
 
void u::set_msg(int a,char s,float h)
{
    age=a;
    sex=s;
    high=h;
}
 
int u::get_age()
{
    return  age;
}
char u::get_sex()
{
    return  sex;
}
float u::get_high()
{
    return high;
}
int main()
{
    u s;
    s.set_msg(18,'w',93.14);
    cout << "age:" <<s.get_age() << endl;
    cout << "sex:" <<s.get_sex() << endl;
    cout << "high:" << s.get_high() << endl;
    return 0;
}

写一个有默认参数的函数，把声明和定义分开，并在主函数内成功调用
