Question

Write C++ mathematics program that a Given an arc with its center at zero, and the arc should be user defined in 3D-space by means of a 3x3 transformation matrix, and a radius, start-angle and sweep-angle should be user defined. it gives output/tells the most extreme XY points that arc goes to

The radius,start angle and sweep angle should be user defined.

make the code quickly and send me

sir the matrix should always be 3x3 center is at zero initially
and raduis,start angle and sweep angle should be user defined
The program should calculate extreme points values of arc
initially assume any assumptions if u don't find sufficient info kindly solve and send me

Answer 1

In this program , I have used the arc() function in the graphics library to generate the arc which accepts following parameters:
arc(x,y,start,end,radius)

Where: x,y are coordinates of the centre

                start is the staring angle of the arc

                end is the ending angle of the arc

                radius is the radius of the arc

Rest all explanations are there in the code itself as comments, wherever required.

CODE:

#include<bits/stdc++.h>
#include <graphics.h>
using namespace std;

int main()

{

// gm is Graphics mode which is a computer display mode that generates image using pixels.
// DETECT is a macro defined in "graphics.h" header file

int gd = DETECT, gm;
   float x,y;
   float start,end;
   float radius;
  
// Getting input for the location of the arc from user
   cout<<"Enter the starting point of the arc.\n";
   cin>>x>>y;
  

// Getting input the start and end angle from user
  
  
    cout<<"Enter the staring and end angle.\n";
cin>>start>>end;

// Getting the radius of the arc as input

   cout<<"Enter the radius of the arc.\n";
   cin>>radius;
  

// The initgraph function initializes the graphics system by loading a graphics driver from disk

initgraph(&gd, &gm, "");

// Calling the arc function to generate the arc

arc(x, y, start, end, radius);

// This closegraph function closes the graphics mode and deallocates all memory allocated by graphics system

closegraph();

return 0;

}

Hope it helps you.
