//把测试程序写在Cycle的main方法里了
C语言编写程序输入任意两个量作为x,y的源码python摇号源码坐标,计算该点到原点的代码线上棋牌软件源码距离及与x轴的夹角。
#include <stdio.h>
#include <math.h>
#define PI 3.
int main ()
{
double x = 0,坐标坐标 y = 0;
double s = 0;
double angle;
printf("请输入x=");
scanf("%lf",&x);
printf("请输入y=");
scanf("%lf",&y);
printf("输入的点坐标为(%f,%f)\n",x,y);
s = sqrt(fabs(x)*fabs(x) + fabs(y)*fabs(y));
angle = atan2(y,x) * /PI;
printf("该点到原点的距离:%lf\n",s);
printf("该点到原点x轴的夹角:%lf°\n",angle);
}
源码如上
运行结果如下
