主要記錄 struct 和 typedef struct的筆記

# include <iostream>
using namespace std;
struct Student
{
    int age;
}stu1;
int main()
{
    stu1.age = 25;
    cout << stu1.age << endl;
    system("pause");
}

# include <iostream>
using namespace std;
typedef struct Student
{
    int
 
 age;
}stu2;
int main()
{
    stu2 L;
    L.age = 25;
    cout << L.age << endl;
    system("pause");
}

使用時可以直接訪問stu1.a
但是stu2則必須先 stu2 s2;

結構體和類的區別

參考博文
結構體 建構函式的實現

# include <iostream>
using namespace std;
typedef struct Student
{
    Student()
    {
        age = 0;
        high = 0
 
;
    };
    Student(int age1, double high1)
    {
        age = age1;
        high = high1;
    }
    int age;
    double high;
}stu1;
int main()
{
    stu1 L;
    cout << L.high << endl;
    system("pause");
}
