C++ :: Getting Multiple Objects To Move Randomly At A Designated Number Of Intervals
Jan 9, 2015
I have a piece of code which gets multiple objects to move randomly at a designated number of intervals. I want to create a function which calculates the distance between each pair of points after that number of steps. so the distance between object 1 and object 2, object 1 and object 3, ..., object 1 and object N. then object 2 and object 3, object 2 and object 4, ..., object 2 and object N. then then object 3 and object 4, object 3 and object 5, ..., object 3 and object N and so on until the distance between all the pairs of points have been calculated.
Is there any way to generate random types I build? I know rand command returns random integers, but I want to create some classes and and a function that will generate randomly 3 objects of the types I have created.
Every time the timer clicks it should show a text letter like (T) for tortoise and (H) for hare that moves around the board when the user hits go on the GUI.
I am writing a pure C based win32 applications. I have drawn line. Now i want to translate that line, move the line whereved user wants to move on screen. Then again I drawn another line, I am drawing multiple lines.
I have created rectangle region for each line and trying to move the line.
When I move the 2nd line over the 1st line on screen the 1st line is getting wiped out. Because I am InvalidateRect() of the rect for the line being moved, so when that rectangle is crossing the other line then the other line is getting removed from the screen.
How can I rectify it. How can I have all the lined being on the screen and moved according to the user's wish. The code should be pure C and win32 no MFC.
I have a error with one of my programs. I'm supposed to get rid of negative numbers when there are numbers that are randomly generated. Here is the middle part of the code.
{ int vectorLength = 10; vector<int> bothSigns(vectorLength); cout << " Input vector: "; for (int i = 0; i < vectorLength; i = i + 1) { bothSigns[i] = rand()%201 - 100;
[code] .....
The part where i'm supposed to start is after the /////'s. However, whenever I input a number for the random numbers(not put in part of code), i keep getting a segmentation error.
IF statement. Really new, so this will be simple I'm sure. I'm essentially just trying to roll a 6 and 20 sided die. I want the statement to run "If 20,then display the randomly selected number for 20".
// auto dice roller #include <iostream> #include <string> #include <ctime> #include <cstdlib> using namespace std;
Essentially, the 'Sequence' below uses linked lists to store data. If 'result' refers to the same sequence as 'seq1' or 'seq2', I want 'result' to refer to a new sequence. This new sequence can be default constructed (no copy of 'seq1' or 'seq2' is required). I can't seem to do this correctly. Also, the prototype of the function cannot be altered.
void fun(const Sequence& seq1, const Sequence& seq2, Sequence& result) { // Check for reference to same sequence. If they are the same, // create new sequence for 'result' to refer to if ((&seq1 == &result) || (&seq2 == &result)) {
My project is to get a file from a designated location in my computer and not just read, but grab the values from the user and make a count, sum, and average calculation of the numbers in my code. I am using the fstream library and I am trying I did do it, I got the values and calcualated them, however I want the values to be accessed from maybe my desktop or my drive, I want to know how to manipulate my code to get a path like C:UserDesktop and maybe executed from the path input or given. I dont know if this is possible, or easy to do. ALso I did copy some of this code from my teachers examples and I dont know exatly why the variables have to be initilized at zero, and I would like to know a little more on the Bitwise right shift breaker used in line 20 something.
Here is my code below.
#include <iostream>//For avergae functionality #include <fstream>//For the file commands, such as ifstream and the Bitwise right breakers(<< and >>). #include <iomanip> // To control the amount of decimals in my results desired. using namespace std; int main () { int aNumber=0; //Initilized at zero because of Stack Overflow:
I'm trying to write a code that displays lines between user designated points with circles at each point, but I can't get the lines to display! I'm at a loss on what to do and need fresh eyes on the subject.
#include <iostream> #include "graph1.h" using namespace std; //Function Prototypes Follow void getNoPoints(int* no_points); void getPoints(int* x, int* y,int no_points); void drawPolyLine(int* x, int* y, int no_points,int objects[]);
[Code] ....
I imagine the error is in this segment:
int i=0; for (i = 0; i < no_points;) { objects[i] = drawLine(x[i],y[i],x[++i],y[++i],1); setColor(objects[i],255,255,0); }
So I have a small program which is supposed to write and read multiple objects from a file, but for some reason it doesn't write the information when I use "fstream" to create the object from the fstream class, but it does when I use "ofstream". Also, it doesn't read the information from the file no matter if I use "fstream" or "ifstream". I watched a video where this exact code worked just fine, but it just won't work when I run it. I'm using Dev C++ 4.9.9.2, I don't know if that has anything to do with it, I also tried it with Code::Blocks, didn't work either.
Here's the code.
#include <iostream> #include <fstream> using namespace std; class Person
I am looking for simple code that subtract two time interval. I have time t1=5hour 30 minute and other time in 24 hour format. This code i written but it not working as expected. it not printing 5:30 minute subtract
Code: main() { intTime1; intTime2; int hour=10; int minute=5; int second=13; int h;int m; doubleNtime;

Is there any easy way of doing above code. Above two code section not working....
I am trying to run a simulation with a large number of objects (mainly arrays and vectors). I am not sure where shall I define my objects: inside or outside of the main() function, like the following two structures:
I know there is a question about scope. But besides this question (which seems have no difference between these two structures here), is there any difference in terms of execution performance or security issue?
How would I be able to round a number in multiples of another...
Let's say width is 150 And multiple to be 64... I want 150 to become 128... if it was 160 to become 192...
The width number will change and I want to covert it in multiples of the other number example 64... The minimum value will always be the multiple number used...
This has been bothering me for a while now, and I finally put together an example:
#include <iostream> #include <string> using namespace::std;
[Code]....
In the code above, the two classes hold pointers to each other, and that's fine but it doesn't seem right since C++ prefers to pass by reference. Yes, it can still do that (see testbox and testball) but even that seems odd to me because still you need to use pointer notation for the enclosed object. Am I the only one who feels this way, and should I just get over it? Or am I missing something that would allow an object to hold a reference?
I am very much a beginner at C and a large amount of it still tends to go over my head, I've created a 2d array which its size is generated from user input and filled with random integers. Next I need to locate the maximum and minimum figures in the integer and as dull..This is the code I have so far
Code:
#include <stdio.h>#include <stdlib.h> int main () { int firstDimension, secondDimension, firstDimensionIndex, secondDimensionIndex,index; int **table; }
So I have a vector that I want to iterate through randomly, and by random I mean that each element is only accessed once but I don't want to shuffle the vector because the vector elements are large. So I want this functionality:
std::vector<SomeLargeObjectWithoutACopyConstructor> myvec; // ...fill myvec std::random_shuffle(myvec.begin(),myvec.end()); for (auto& value : myvec) { // do stuff }
Only I don't want to do this because the object type has no copy constructor and is large, so I don't want to shuffle the vector, just the iteration path. Is there a simple and efficient way of iterating randomly through a vector while ensuring that each object is only accessed once?
I am making a game and I am attempting to get the zombies to move randomly but for the life of me, I simply don't have the knowledge with srand to do it
I can't get the sum of two randomly generated numbers - I don't believe the program is adding wrong what I think might be happening is upon hitting enter its adding two new randomly generated numbers -
Code: // Program functions as a math tutor #include <cstdlib> #include <iostream> #include <ctime> using namespace std; int main() { // Constants const int Min_Value = 1;
