wenbao与类

不知道是什么鬼。。。。

#include <iostream>
#include <cmath>
using namespace std;
struct Tpoint{
    int x, y, z;
    void init(int a, int b, int c){//初始化（赋值）
        x = a, y = b, z = c;
    }
    Tpoint operator + (const Tpoint &m){//重载+
        Tpoint T;
        T.x = m.x + x, T.y = m.y + y, T.z = m.z + z;
        return T;
    }
    Tpoint operator - (const Tpoint &m){//重载-
        Tpoint T;
        T.x = x - m.x, T.y = y - m.y, T.z = z - m.z;
        return T;
    }
    double dist(Tpoint n){//计算距离
        return sqrt(pow((double)(x-n.x), 2) + pow((double)(y-n.y), 2) + pow((double)(z-n.z), 2));
    }
    void read(){//读取
        printf("x = %d, y = %d, z = %d
", x, y, z);
    }
};
int main(){
    Tpoint T, N, M;
    T.init(1, 2, 3);
    T.read();
    N.init(2, 3, 4);
    N.read();
    M = T + N;
    M.read();
    M = T - N;
    M.read();
    printf("%lf
", T.dist(N));
    return 0;
}

只有不断学习才能进步！
