我这输入输出真的没毛病吗
#include <cstdio> class triangle { private: int y, x; // 分别代表A和B的纵坐标和横坐标 public: triangle(int y = 0, int x = 0) : y(y), x(x) {} int display_x() { return x; } int display_y() { return y; } triangle operator+(const triangle &other) { return triangle(y + other.y, x + other.x); } }; int main() { int a, b; triangle ans; while (scanf("%d%d", &a, &b) != EOF) { if (!a) break; // 某条边长度是0,不是三角形,跳过 triangle tri(a, b); ans = ans + tri; } printf("A(0,%d),B(0,0),C(%d,0)\n", ans.display_y(), ans.display_x()); return 0; }
