HAVE TO BE SOLVED WİTH C PROGRAMMİNG

A programming task is given in below (i.e., you are supposed to write a single program involving all 5 tasks in below). You should write a C program and upload your c/cpp file .
Students are allowed to use MAK104E course (powerpoint) slights.

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
struct Circle

{

double x;

double y;

double r; };
struct rectangle

{

double xBottomLeft;

double yBottomLeft;

double xtopRight;

double ytopLeft; };
struct Triangle

{

double x1;

double y1;

double x2;

double y2;

double x3;

double y3; };
these three geometrric entities can/should be represented using the following C struct samples in your program:

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.
  
2) Write three functions for each geometric entity that samples 300 points on these geometries and returns these points. Note that these points should be represented using a linked list as in below (in such a way that Pt1
--> Pt2 --> .... --> Pt300 --> NULL).
Use pointers to represent these linked lists. Do not forget allocate memory (new) for pointers and deallocate (free) after using them.
struct point
{
double x;
double y;
struct point *pnext;
};

{

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..

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();
