C ++程序显示线和点的对偶转换
这是一个C++程序，用于显示线和点的对偶转换。所以它可以有两种情况-
情况1：点(a,b)变换为线（y=ax-b）。
情况2：线D（y=cx+d）变换为点D'(c,-d)。
函数和伪代码
函数LineTransformation（doublec，doubled）
Print C: (d / c) D: (d * -1)
功能PointTransformation（doublex，doubley）
Print a = (-1 * y / x) b = (-1 * y)
示例
#include <iostream>
#include <time.h>
#include <stdlib.h>
using namespace std;
void LineTransformation(double c, double d) {
cout << "C: " << (d / c) << ", D: " << (d * -1);
}
void PointTransformation(double x, double y) {
cout << "y=" << (-1 * y / x) << "x +" << (-1 * y);
}
int main(int argc, char **argv) {
cout << "\n1. Line Transformation\n2. Point Transformation";
int c;
cin >> c;
switch (c) {
case 1:
cout << "Enter the coefficients of line y=ax-b:";
double a, b;
cin >> a >> b;
LineTransformation(a, b);
break;
case 2:
cout << "Enter the coordinate of point <a, b>";
double x, y;
cin >> x >> y;
PointTransformation(x, y);
break;
default:
break;
}
}输出结果
1. Line Transformation 2. Point Transformation 1 Enter the coefficients of line y=ax-b: 1 2 C: 2, D: -2 1. Line Transformation 2. Point Transformation 2 Enter the coordinate of point <a, b> 1 2 y=-2x +-2
