wenbao与类
不知道是什么鬼。。。。
1 #include <iostream> 2 #include <cmath> 3 using namespace std; 4 struct Tpoint{ 5 int x, y, z; 6 void init(int a, int b, int c){//初始化（赋值） 7 x = a, y = b, z = c; 8 } 9 Tpoint operator + (const Tpoint &m){//重载+ 10 Tpoint T; 11 T.x = m.x + x, T.y = m.y + y, T.z = m.z + z; 12 return T; 13 } 14 Tpoint operator - (const Tpoint &m){//重载- 15 Tpoint T; 16 T.x = x - m.x, T.y = y - m.y, T.z = z - m.z; 17 return T; 18 } 19 double dist(Tpoint n){//计算距离 20 return sqrt(pow((double)(x-n.x), 2) + pow((double)(y-n.y), 2) + pow((double)(z-n.z), 2)); 21 } 22 void read(){//读取 23 printf("x = %d, y = %d, z = %d\n", x, y, z); 24 } 25 }; 26 int main(){ 27 Tpoint T, N, M; 28 T.init(1, 2, 3); 29 T.read(); 30 N.init(2, 3, 4); 31 N.read(); 32 M = T + N; 33 M.read(); 34 M = T - N; 35 M.read(); 36 printf("%lf\n", T.dist(N)); 37 return 0; 38 }
只有不断学习才能进步！
