Question

1) Three geometric entities (a circle, a rectangle and a triangle) should be first randomized using rand function in line with srand(time(NULL)). These three geometrric entities can/should be represented using the following C struct samples in your program: struct Circle { double x; double y; doubler; }; struct Rectangle { double xBottomLeft; double yBottomLeft; double xTopRight; double y TopRight; }; struct Triangle double x1; double y1; double x2; double y2; double x3; double y3; }; Write three functions for each geometric entity that randomizes the geometric parameters (such as center X and Y coordinates and radius for a circle) and returns these geometries (such as struct Circle, struct Rectangle and struct Triangle). Note that floating numbers should be randmized from 0 to 10.

Answer 1

Ideas is simple to randomize the number using the range [0 10 ] an dwe use use the two random numbers in int to divide each other to get the same

#include<stdio.h>

#include<stdlib.h>

#include<time.h>

struct Circle

{

    double x;

    double y;

    double r;

    

};

struct Circle randomize_circle()

{

    struct Circle c1;

    double a=10;

    /*here a=10 is the range from 0 to 10 upt0 which we

    want to get the double values. as defined here.

    since we cant get the direct random double values so

    we find random int values in range of 0 to RAND_MAX

     and then we divide it by RAND_MAX to get it in range of

     [0 to 1] and then we multiply it with 10 to get the

      to get it in range of [0 10]..

    */

    c1.x= (double)(rand()*a)/(double)(RAND_MAX);

   

    c1.y=(double)(rand()*a)/(double)(RAND_MAX);

    c1.r=(double)(rand()*a)/(double)(RAND_MAX);

      //assingn the random x ,y and return c1..

    return c1;

    

}

//we have the rectangle as x y and x top and y top here as defined

struct rectangle

{

    double xBottomLeft;

    double yBottomLeft;

    double xtopRight;

    double ytopLeft;

    

};

struct rectangle randomize_rectangle()

{

    struct rectangle r1;

    double a=10.00;

    r1.xBottomLeft=(double)(rand()*a)/(double)(RAND_MAX);

    r1.yBottomLeft=(double)(rand()*a)/(double)(RAND_MAX);

    r1.xtopRight=(double)(rand()*a)/(double)(RAND_MAX);

    r1.ytopLeft=(double)(rand()*a)/(double)(RAND_MAX);

    return r1;

    

}

struct Triangle

{

    double x1;

    double y1;

    double x2;

    double y2;

    double x3;

    double y3;

    

};

//we get the randomize_triangle and randomize_rectangle as defined...

struct Triangle randomize_triangle()

{

    struct Triangle t1;

    double a=10.00;

    t1.x1=(double)(rand()*a)/(double)(RAND_MAX);

    t1.y1=(double)(rand()*a)/(double)(RAND_MAX);

    t1.x2=(double)(rand()*a)/(double)(RAND_MAX);

    t1.y2=(double)(rand()*a)/(double)(RAND_MAX);

    t1.x3=(double)(rand()*a)/(double)(RAND_MAX);

    t1.y3=(double)(rand()*a)/(double)(RAND_MAX);

    return t1;

    

}

int main(){

    

   srand((unsigned int )time(NULL));

    

    //we randomize_circle the teh rectangle and Triangle and get the rectangle

   struct Circle c2= randomize_circle();

   struct rectangle r2= randomize_rectangle();

   struct Triangle t1=randomize_triangle();

    

    

return 0;

}
