为什么我在VScommunity2017上编写的程序无法运行？但是程序可以在2015上面运行？
1、'Coordinate': is not a class or namespace name
2、~Coordinate': destructor tag mismatch
......等诸多问题

coordiante.h
class coordinate
{
public:
coordinate(int x, int y);
~coordinate();
int getx();
int gety();
public:
int m_ix;
int m_iy;
};
coordinate.cpp
#include"coordinate.h"
#include<iostream>
using namespace std;
coordinate::coordinate(int x, int y)
{

m_iy = y;
cout << "(" << m_ix << "," << m_iy << ")" << endl;
}
coordinate::~coordinate()
{
cout << "我是析构函数" << endl;
}
int coordinate::getx()
{
return m_ix;
}
line.h
#include"coordinate.h"
class line
{
line(int x1, int y1, int x2, int y2);
~line();
void printinfo();
private:
coordinate *m_pcoora;
coordinate *m_pcoorb;
};
line.cpp
#include"line.h"
#include<iostream>
using namespace std;
line::line(int x1, int y1, int x2, int y2)

m_pcoorb = new coordinate(x2, y2);
cout << "line" << endl;
}
line::~line()
{
delete m_pcoora;
m_pcoora = NULL;
delete m_pcoorb;
m_pcoorb = NULL;
cout << "~line" << endl;
}
void line::printinfo()

}
main.cpp
#include<iostream>
#include"line.h"
using namespace std;
int main()
{
line *p = new line(1, 2, 3, 4);
delete p;
