Thanks for the question, here is the code in C

Let me know for any help with any other quesitons.

=====================================================================

#include<stdio.h>

#include <stdlib.h>

//------ POINT ----------------------------------------------------------------

typedef struct point point;

struct point { double x, y; };

//------ SQUARE -----------------------------------------------------------------

typedef struct square square;

struct square { point ul; size_t side; };

square* square_init(double ulx, double uly, double side) // TODO

{

                square* p = (square*)malloc(sizeof(square))        ;

                p->ul.x = ulx;

                p->ul.y = uly;

                p->side = (size_t)side;

                return p;

}

                return (sq->side)*(sq->side);

}

double square_perimeter(square* r) // TODO

return 4*(r->side);

}

square_print(char* msg, square* sq){

                printf(msg);

                printf("Point: %.2lf by %.2lf, Area: %.2lf, Perimeter: %.2lf \n",sq->ul.x,sq->ul.y,square_area(sq),square_perimeter(sq));

}

// print location, side, area and perimeter

void test_square(double ulx, double uly, double side) {

square_print("sq is: ", sq);

square_print("sq has expanded to: ", sq);

square_delete(sq);

printf("\n\n");

}

void tests_square() {
