计算2点之间的距离
1 #include <stdio.h> 2 #include <math.h> 3 int mydistance(int a,int b,int c,int d); 4 int main() 5 { 6 char buff[8]; 7 int buffer[4]; 8 while(gets(buff)) 9 { 10 buffer[0] = buff[0] - ‘0‘; 11 buffer[1] = buff[2] - ‘0‘; 12 buffer[2] = buff[4] - ‘0‘; 13 buffer[3] = buff[6] - ‘0‘; 14 printf("%d\n",mydistance(buffer[0],buffer[1],buffer[2],buffer[3])); 15 } 16 return 0; 17 } 18 19 int mydistance(int a,int b,int c,int d) 20 { 21 int e; 22 e = sqrt((c - a)*(c - a) + (d - b)*(d - b)); 23 return e; 24 }
参考c++
1 #include <cmath> 2 #include <cstdio> 3 4 int main(void) 5 { 6 double x[2], y[2]; 7 8 while (scanf("%lf%lf%lf%lf", x, y, x+1, y+1) != EOF) 9 printf("%.2f\n", sqrt((x[1]-x[0])*(x[1]-x[0]) + (y[1]-y[0])*(y[1]-y[0]))); 10 11 return 0; 12 }
