C++ :: Send Rectangle To A Function Which Takes A Rectangle Argument

May 13, 2014

Consider I have a rectangle like this:

Point p1(100,100);
Point p2(300,200);
Graph_lib::Rectangle r(p1,p2);

And also I have a function that takes a rectangle and returns a Point of that, say, top-left corner of that rectangle. For example:

Point N(Graph_lib::Rectangle R1);

My question is that, first, how to send that Rectangle r(p1,p2) to the Point N(Graph_lib::Rectangle R1) function? And then, how to return a Point from that function?

My IDE is visual studio 2012.

C++ :: Representing A Rectangle With Only 3 Variables Instead Of 4

Apr 6, 2013

how to use 3 variables to represent a rectangle in a grid instead of using 4. The traditional way is to use (x,y) (x2,y2). I propose using (x,l,h).In the traditional way as you probably know, (x,y) is the left op most corner, and (x2,y2) is the bottom right most corner. In the way I am proposing X is the left side, l is the length of the top side, and also the length of the bottom. 'h' is the height of the left and right. I think it's obvious how these three can define a rectangle same as the four.

C# :: Indexing Through Rectangle List?

Mar 11, 2014

I have having trouble looping through the list in the update section to update each object in the rectangleList. I am not sure how to format it because it is only drawing one and it does not move across the screen. I thought this section of code would work and loop through each object and make each one move but it does not.

for (int i = 0; i < rectangleList.Count; i++) {
enemyPosition = new Rectangle(rectangleList[i].X + 2, rectangleList[i].Y ,enemyPosition.Width,enemyPosition.Height);
} List<Rectangle> rectangleList;
protected override void Initialize() {
rectangleList = new List<Rectangle>();

C :: Produce A Rectangle Out Of Asterisks Using While Loops

Jan 30, 2015

I am new to C and am unfortunately racking my brain against this simple assignment. I believe the task is to produce a rectangle out of asterisks using while loops, yet I can only produce an "L" shape. We were given a code, with syntax errors included.We are to correct the errors and test.

Code:

#include <stdio.h>

C++ :: Calculate Area Using Rectangle / Trapezoid Or Both

Feb 17, 2014

#include <iostream>
#include <cmath>
using namespace std;

//prototypes for all separate functions
int chooseFunc(int);
int chooseMethod(int);
int numRect(int);

[Code] .....

It seems that my program will ask the user for the number of rectangles and trapezoids but will fail to compute the area under the curve from the user input. Therefore, I believe I have a logical error somewhere or I'm forgetting to call something somewhere.

C/C++ :: Subtracting Area Of Two Circles From A Rectangle

C/C++ :: How To Use Rectangle Height And Width In Functions

May 13, 2014

The problem says:

Define functions n(), s(), e(), w(), center(), ne(), se(), sw() and nw(). Each takes a Rectangle argument and returns a Point. These functions define connection points on and in the rectangle. For example, nw® is the northwest (top-left corner) of a rectangle called r.

I wrote below code for that:

#include <Simple_window.h>
Point n(const Graph_lib::Rectangle& r);
Point s(const Graph_lib::Rectangle& r);
Point e(const Graph_lib::Rectangle& r);
Point w(const Graph_lib::Rectangle& r);
Point ne(const Graph_lib::Rectangle& r);
Point se(const Graph_lib::Rectangle& r);

[Code]...

As you see, this just mark the top-left corner of the rectangle r. In other functions I need the specifications of that rectangle, for example its height and width. How to use these specs in those functions?

C# :: Drawing Rectangle On Bitmap (Mandelbrot)

Nov 3, 2014

I've been given the task of converting a java application to a c# windows form application. The program displays a Mandelbrot which then allows the user to zoom into. I've managed to display the Mandelbrot and even zoom. However when dragging a box to zoom, the box its self doesn't show, meaning the user cannot see what area they will be zooming into.

I believe I need to call the update function which draws the rectangle as I drag however no matter what I try, I get errors from a red cross instead of the Mandelbrot to compile errors. Here is the code that I believe is relevant.

public void update(Graphics g) {
Color color = Color.White;
Pen myPen = new Pen(color);
g.DrawImage(myBitmap, 0, 0);
if (rectangle) {

C++ :: Calculate Area And Perimeter Of A Rectangle

Jan 28, 2013

Write a program that prompts the user to input the length of a rectangle and the width of a rectangle and then displays the rectangle's area and perimeter. The program should be broken down in 3 parts:

1. Input the length and the width (two input statements)

2. Calculate the area & perimeter (results should be saved in variables

3. print results.

Format the output so the user can easily read the results. Use the tab escape so its easy to read.
---------------------------------------------------------------
So here's what I have so far. I have been stuck for two days

#include iostream
using namespace std;
int main () {
int double length;
int width;
int area;
int perimeter;

[Code] ....

I dont want to get a zero for not turning this in...

C :: Calculate Area Of Rectangle - Variable R Is Being Used Without Being Initialized

Mar 15, 2014

I am writing a program to calculate a rectangle's area.

Eg.
Enter top left point: 1 1 (User input)
Enter bottom right point: 2 -1 (User input)
Top Left x = 1.000000 y: 1.000000
Bottom Right x = 2.000000 y: -1.000000
Area = 2.000000 (Program output)

It keeps on prompting me my variable r is being used without being initialized, when I think I already did so.

Code:
typedef struct {
double x;
double y;
} Point;

C :: Creating PPM Image - Black Rectangle With A Circle

Mar 12, 2013

I'm trying to create a PPM image for a class assignment. A black rectangle with a circle at the point 225, 175 with a radius of 75. I have to use certain specific methods, so I can't use like Bresenham's really famous method for creating a circle.

The problem is that it compiles fine, and transfers to an image fine, but always says that I have a negative or zero image size.

Code:

#include "shapes.h"
int main () {
int i, j, x, y;

fprintf(stdout,"P6 width height 255
");

[Code] ....

And my header is:

Code:
#include <stdio.h>#include <math.h>
#define height 480
#define width 640
#define cy 175
#define cx 225
#define radius 75

The circle has to be filled in. I made it white. Also, i and j are unsused so far, so just ignore them.

C/C++ :: Rectangle Not Resizing Properly - Odd Multiplication Result

May 28, 2014

I'm having some issues understanding why the "rectangle" in the following code isn't resizing properly. Here's the code:

#include <iostream>
using namespace std;
class Rectangle {
public:
Rectangle(double w, double h, double f)
: width(w), height(h), factor(f)

[Code] .....

I tested the code with a simple multiplication factor of "2", which should result in a new width and height of 4, but instead I get an odd value that seems be close to 4.

Output:

Numerically enter the width of the rectangle: 1
Numerically enter the height of the rectangle: 1

The width of the rectangle is: 1
The height of the rectangle is: 1
The area of the rectangle is: 1
The perimeter of the rectangle is: 4

Numerically enter a number to resize the rectangle: 2

The width of the rectangle after resizing is: 2.07408e-317
The height of the rectangle after resizing is: 2.07408e-317

C Sharp :: Implement Drag And Drop For Rectangle

Oct 12, 2012

I would like to know the simplest way to implement a drag and drop feature for my rectangles I draw up.

I can select the rectangles and I know I have to get the old position to equal the new position but wouldn't know how to actually do this.

I would think that I would have to put it into MouseMove but again, not sure.

public:
CrectTracker m_tracker;//Changed to CRectTracker

};

Secondly, in the constructor to initialize the object CRectTracker document class:

CSampleDoc :: CSampleDOC () {
// Initialize tracker position, size and style.
m_tracker.m_rect.SetRect (0, 0, 10, 10);
m_tracker.m_nStyle = CRectTracker :: resizeInside |
CRectTracker :: dottedLine;
}

The error is:

error C2065: 'm_tracker' : undeclared identifier

How to get rid of this error??
