vscode 明明已经定义了C++类, 为什么还是显示undefined reference

Question

#include <iostream>
#include "student.h"
using namespace std;

int main()
{
    Student s1;

    return 0;
}

PS D:\C++\xxx\xx> cd "d:\C++\Cspace\test" ; if ($?) { g++ 'main.cpp' -o 'main.exe' -Wall -g -O2 -static-libgcc -std=c++17 -fexec-charset=GBK } ; if ($?) { &'.\main' }

D:\C++\Cspace\test/main.cpp:7: undefined reference to `Student::Student()'

D:\C++\Cspace\test/main.cpp:7: undefined reference to `Student::~Student()'

collect2.exe: error: ld returned 1 exit status

Answer 1

写构造函数和析构函数了么 是不是只写了带参数的构造函数
