我只是在学习构造函数和析构函数我正在学习这个人正在做的教程bucky tutorial .我觉得视频过时了？因为我遵循了他说的每一步，但我仍然遇到错误。
main.cpp
#include <iostream>
#include "TESTING.h"
using namespace std;
int main(){
TESTING so;
cout << "TEST" << endl;
}
测试.h
#ifndef TESTING_H
#define TESTING_H
class TESTING
{
public:
TESTING();
protected:
private:
};
#endif // TESTING_H
测试.cpp
#include "TESTING.h"
#include <iostream>
using namespace std;
TESTING::TESTING()
{
cout << "TESTTTTT!!" << endl;
}
错误信息
