错误 2 error LNK1120: 1 个无法解析的外部命令
CSND上的大神们 这个怎么弄啊 头文件.c：
#ifndef COORDIN_H_
#define COORDIN_H_
struct polar
{
double distance;
double angle;
};
struct rect
{
double x;
double y;
};
polar rect_to_polar(rect xypos);
void show_polar(polar dapos);
#endif
函数实现.cpp：
#include <iostream>
#include <cmath>
#include "coordin.h"
polar rect_to_polar(rect xypos)
{
using namespace std;
polar answer;
answer.distance = sqrt(xypos.x * xypos.x + xypos.y * xypos.y);
answer.angle = atan2(xypos.y, xypos.x);
return answer;
}
void show_polar(polar dapos)
{
using namespace std;
const double Rad_to_deg = 57.29577951;
cout << "distance = " << dapos.distance;
cout << ", angle = " << dapos.angle * Rad_to_deg;
cout << " degrees\n";
}
源文件.cpp：
#include <iostream>
#include "coordin.h"
using namespace std;
void main(void)
{
rect rplace;
polar pplace;
cout << "Enter the x and y values: ";
while (cin >> rplace.x >> rplace.y)
{
pplace = rect_to_polar(rplace);
show_polar(pplace);
cout << "Next two nubers (q to quit): ";
}
cout << "Bye!\n";
}
