CS602 – Computer Graphics Assignment 3 Fall2011

	Assignment No. 03 Fall 2011 CS602 – Computer Graphics	Total Marks: 20 Due Date: December 28, 2011
Question                                      20 marks In the handouts of CS602 – Computer Graphics many examples are given in which GRAPHICS.H Header file is used. If you compile the given code in Dev-C++ IDE / Compiler the errors are reported because the given code is using GRAPHICS.H which is originally provided by Borland (www.borland.com). But there are ways to compile that code on Dev-C++. For this purpose you can consult the following tutorials: http://vulms.vu.edu.pk/Courses/CS602/Downloads/DevCppTutorialGraphics_h.pdf http://www.uniqueness-template.com/devcpp/ You are required to compile the given code after following the above tutorial and submit the following files in zip archive: Dev-C++ Project File (e.g. Project1.dev) C++ Source (e.g. main.cpp) O/Object File (mian.o) Makefile.win Executable File (e.g. Project1.exe) it is much necessary as a proof that you have successfully compiled the code. Microsoft Word File explaining the code. Source Code: #include <graphics.h> #include <iostream> #include <conio.h> #include <math.h> float round(float x){       return x+0.5; } class Table{ private:         int xc, yc;         int xp, yp;         int x1, x2, x3, x4;         int y1, y2, y3, y4;         int legLength;         int sfx, sfy; public: Table(){         xc=320, yc=240;         xp=0; yp=0;         x1=-10, x2=10, x3=10, x4=-10;         y1=-7, y2=-7, y3=7, y4=7;         legLength=10;         sfx=1, sfy=1; } void translate(int tx, int ty){         xp+=tx;         yp+=ty; } void rotate (float angle){         int tempx=x1;         x1=tempx*cos(angle)-y1*sin(angle);         y1=tempx*sin(angle)+y1*cos(angle);         tempx=x2;         x2=tempx*cos(angle)-y2*sin(angle);         y2=tempx*sin(angle)+y2*cos(angle);         tempx=x3;         x3=tempx*cos(angle)-y3*sin(angle);         y3=tempx*sin(angle)+y3*cos(angle);         tempx=x4;         x4=tempx*cos(angle)-y4*sin(angle);         y4=tempx*sin(angle)+y4*cos(angle); } void scale(int sx, int sy){         x1=x1*sx;         x2=x2*sx;         x3=x3*sx;         x4=x4*sx;         y1=y1*sy;         y2=y2*sy;         y3=y3*sy;         y4=y4*sy;         legLength=legLength*sy; } void draw(){         int xc=this->xc+xp;         int yc=this->yc+yp;         line (xc+x1, yc+y1, xc+x2, yc+y2);         line (xc+x2, yc+y2, xc+x3, yc+y3);         line (xc+x3, yc+y3, xc+x4, yc+y4);         line (xc+x4, yc+y4, xc+x1, yc+y1);         line (xc+x1, yc+y1, xc+x1, yc+y1+legLength);         line (xc+x2, yc+y2, xc+x2, yc+y2+legLength);         line (xc+x3, yc+y3, xc+x3, yc+y3+legLength);         line (xc+x4, yc+y4, xc+x4, yc+y4+legLength); }}; int main(){         //clrscr(); //it is not needed in DevCPP         int gdriver = DETECT, gmode, errorcode;         initgraph(&gdriver, &gmode, "c:\\Dev-Cpp\\lib");         Table table;         table.draw();         setcolor(CYAN);         table.translate(15, 25);         table.draw();         table.translate(50, 0);         table.scale(3,2);         table.draw();         table.translate(-100, 0);         table.rotate(3.14/4);         table.draw();         getch();         closegraph(); return 0; }
