}然后是vector2.cpp
//头文件要求
#include <cmath>
struct vector2
{

vector2(int* data):x(data[0]),y(data[1]){}

};
//加法

}
//减法
vector2 operator -(vector2 x, vector2 y) {

}
// 乘法
vector2 operator *(vector2 x, vector2 y) {

}
// 乘法
vector2 operator *(vector2 y, float x) {

}
vector2 operator *(float x, vector2 y) {
return vector2(x * y.x, x * y.y);
}
//叉积
long long cross(vector2 x, vector2 y) { return x.y * y.x - x.x * y.y; }
//数量积 点积
long long dot(vector2 x, vector2 y) { return x.x * y.x + x.y * y.y; }
//四舍五入除法
long long dv(long long a, long long b) {//注意重名！！！
return b < 0 ? dv(-a, -b)
: (a < 0 ? -dv(-a, b)
: (a + b / 2) / b);
}
//模长平方
long long len(vector2 x) { return x.x * x.x + x.y * x.y; }
//模长
long long dis(vector2 x) { return sqrt(x.x * x.x + x.y * x.y); }
//向量除法
vector2 operator /(vector2 x, vector2 y) {
long long l = len(y);
return vector2(dv(dot(x, y), l), dv(cross(x, y), l));
}
//向量膜
vector2 operator %(vector2 x, vector2 y) { return x - ((x / y) * y); }
//向量GCD
vector2 gcd(vector2 x, vector2 y) { return len(y) ? gcd(y, x % y) : x; }
vector2 calcBezierPoint(float t, vector2 p0, vector2 p1, vector2 p2, vector2 p3) {
float u = 1 - t;
float tt = t * t;
float uu = u * u;
float uuu = uu * u;
float ttt = tt * t;
vector2 p = uuu * p0;
p = p + 3 * uu * t * p1;
p = p + 3 * u * tt * p2;
p = p + ttt * p3;
return p;
}
最后头文件tools.h
#pragma once
#include <graphics.h>
void putimagePNG(int picture_x, int picture_y, IMAGE* picture);
int getDelay();vector2.h
#pragma once
//头文件要求
#include <cmath>
struct vector2 {
vector2(int _x=0, int _y=0) :x(_x), y(_y) {}
vector2(int* data) :x(data[0]), y(data[1]){}
long long x, y;
};
//加法
vector2 operator +(vector2 x, vector2 y);
//减法
vector2 operator -(vector2 x, vector2 y);
// 乘法
vector2 operator *(vector2 x, vector2 y);
vector2 operator *(vector2, float);
vector2 operator *(float, vector2);
//叉积
long long cross(vector2 x, vector2 y);
//数量积 点积
long long dot(vector2 x, vector2 y);
//四舍五入除法
long long dv(long long a, long long b);
//模长平方
long long len(vector2 x);
//模长
long long dis(vector2 x);
//向量除法
vector2 operator /(vector2 x, vector2 y);
//向量膜
vector2 operator %(vector2 x, vector2 y);
//向量GCD
vector2 gcd(vector2 x, vector2 y);
vector2 calcBezierPoint(float t, vector2 p0, vector2 p1, vector2 p2, vector2 p3);这里给大家演示一下画面
