I'm trying to draw and pivot a rectangle. How to get the new coordinates if I turn it 90 degree for example?
From this:
To this:
This is not good because it will reduce it in size.
Code:
int size = 50;
if(b) // draw rectangle
{
POINT points[4] =
{{xCoord, yCoord},
[Code] ....
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.
I have the code to make the text roll. But the problem is that the application can't execute other instructions coz its busy in the infinite loop of the marquee. How do i make the application to execute its normal instructions as well as roll the text simultaneously
View 7 Replies View RelatedI saw a program in which it uses rand like this:-
d1=rand() % 6+ 1;
where, d1 is any integer. The program is to simulate the roll of a dice. The whole program is this:-
Code:
#include<stdio.h>
#include<stdlib.h>
main() {
int i;
int d1, d2;
int a[13];
[Code] .....
My issue is that my program dies whenever it attempts to readout the average and sum of the rolls. I think I need to include the size function in here somewhere but am not sure how to go about it. Possibly scrap the "do while" loop and go with something else, or just am completely missing something.
Here's the code:
#include<iostream>
#include<random>
#include<ctime>
#include<vector>
#include<cstdlib>
#include<iomanip>
using namespace std;
int sum5(int d1, int d2, int d3, int d4, int d5);
int DiceRoll();
[Code] ....
Why certain projects always roll their own data structures/utililiy classes rather than using the C++ standard libraries? such as linked lists and queues? Is there a particular reason for this?

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.
View 2 Replies View RelatedI 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;

rectangleList = new List<Rectangle>();

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.

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.

// subtracting the area of two circles from a rectangle

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?
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;

View 2 Replies View RelatedHow to move a rectangle in TabPage ?
View 2 Replies View RelatedWrite 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.

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;
