空间中两点间距离
#include<stdio.h>#include<math.h>
int main()
{
float GPS1,GPS2;
int i=0,j=0;
float d;
printf("Please input the first coordinate of the point:\n");
for(i;i<3;i++)
{
scanf("%f",GPS1);
}
printf("Please input the second coordinate of the point");
for(j;j<3;j++)//从这开始代码就没有继续运行下去了，为什么？如何改进？
{
printf("--------");
scanf("%f",GPS2);
}
d=sqrt((GPS1-GPS2)*(GPS1-GPS2)
+(GPS1-GPS2)*(GPS1-GPS1)
+(GPS1-GPS2)*(GPS1-GPS2));
printf("The distance of the two points is %f",d);
return 0;
} 两个输入函数没有&符号 scanf() 读取数值给出的参数必须是变量地址，不可以直接使用变量本身。
#include<stdio.h>
#include<math.h>
int main(void)
{
float d , e , GPS ;
int i , j ;
for(i = 0 ; i < 2 ; i ++) {
printf("Please input the No. %d coordinate of the point:\n" , i + 1) ;
for(j = 0 ; j < 3 ; j ++) scanf("%f" , & GPS) ;
}
for(e = 0.0 , i = 0 ; i < 3 ; i ++) e += (GPS - GPS) * (GPS - GPS) ;
d = sqrt(e) ;
printf("The distance of the two points is : %.6f\n" , d) ;
}
