I've been working on a little experiment, here is the source: [URL]
The problem that I keep running into is when I run the initPop and generate an individual object, the genome of the next individual is _exactly_ the same as the previous one... which confuses me... Shouldn't each individual be randomly different from the one that preceded it? What am I not right when it comes to generating random values?
I want to make 10 random numbers thus making 10 random flips of a coin. I am getting 10 tails or 10 heads!

i have to find 2 random values between a range, lets say from 0-3 i have to find all the possible combinations between this range like (0,0),(0,1)...etc But, it has to be RANDOM and the same combination cannot repeat it self(obviously).

Im trying to generate random numbers between -32767 and +32767, where im going wrong, this code generates only negative numbers
I'm currently working on a code, its a wheel of fortune type of game. I have specific values of an array of size 10, and i have to get these at a random. so they would not print out in order. but how to assign each value of the random to the array.
#include <stdlib.h>
#include <stdlib.h>
#define CHANCES 5
int main(void){
int num, i;

I am having trouble getting values of a dictionary to display in a label and radio button text after the dictionary key is randomly selected.
I first created a class called TheoryQuestions and created a new instance of the class for each dictionary entry. Each entry contains strings for Question, RadioButton Text(x4), and Correct Answer.
The random generator is actually selecting a random number as I can display the generated number in a label. The problem is that the dictionary string values held in the dictionary position represented by the random number are not being displayed.
Here is my TheoryQuestion Class
public class TheoryQuestion {
bool BeenAsked = false;
public string Question
{
get;
set;
}

Its probably some mistake I have made but I just can't see it.
The only part I have working is getting all odd random numbers but the logic in getting the largest and smallest from random is what is giving me alot of trouble.
class Program {
static void Main(string[] args){
int num = 0;
int largest = 0;
Random rand = new Random();
for (int ctr = 1; ctr <= 100; ctr++)
[code]....
Console.Write("{0,5} The larget number out of 100 odd numbers is: {1:n}",y,largest);
my motive is to get random variable at every start of program.so it does not show same sequence when it run again and again
int main()
{
srand( time ( NULL ) );
cout<<rand();
}
when i run this program in code::block the following program is opening with error in new tab called TIME.H

Where those 0s come from nor how to get rid of them. I'm also having trouble putting the output in table format but thats just a minor issue.
I'm trying to generate random number from 7 to 10 but all i got is "Error C2661: 'rand' : no overloaded function takes 1 argument"

i want to create an arry with random value. in 50% times the average of this array is upper of 0.5 and in 50% times the average of this array is lower of 0.5 . i want to write this code in C++. but i dont know what the algorithm is.
My code is this.
#include <algorithm>
#include <cstdlib>
#include <iostream>
int main() {
int a[10] = {0, 1, 2, 3, 4, 5, 6, 7,8 ,9};
std::srand(unsigned(std::time(0)));
}
When I run this program it always generates the number 41 or 42. Why is this? Even if I add the code
magic = rand()%100 + 1;
to specify a range of 1 to 100 it's still always 41 or 42.
This is exactly the same code my book uses just without the cout << magic statement
#include<iostream>
#include<cstdlib>
using namespace std;

int gameplays, n, prize, choice1;

So in this code, the user inputs the amount of games he/she wants the program to simulate. For each game, a "prize" is randomly placed in one out of three doors. My problem is that for each game simulated, the prize is always placed in the same door. How do i fix this? I used the stand function but it still doesn't work.
i have some mathematics instruction to resolve
|z - c| =< r and|z - w| =< d
Because i want just one number , i used randomise
Code:
mini =min((d-w),(c-r));
maxi=max((d+w),(r+c));
z=mini + (rand()%(maxii - minii));
It give me random number but when i use it to calculate another
Code:
f=sqrt(pow(d,2)-pow((z-w),2));
It give me error because many times the "z"is very height
so i get negative inter the sqrt.how i resolve this problem ? shall i add another limit to the Z?
I'm trying to make a C++ program that generate 6 random numbers ( from 100,000 to 999,999 ), okay, so I wrote a few lines..
Code:
srand(time(0));
for (int i = 0; i < 5; i++)
{
std::cout << 100000 + (rand() % 999999) << std::endl;
}
The problem is, that it generates numbers like this:
117,207
123,303
131,083
... etc etc..
They're all starts with 100K, i want them to be an actual random..
My program behaves weird... I wanted to generate 10 random numbers from 1 to 100 each of them bigger than previous, using the while loop and function that returns a random number in specified range.
When I run the program, I get numbers much bigger than 100, even negative number, and numbers are same every time I run the program.
Code:
#include <ctime>#include <cstdlib>
#include <iostream>
using namespace std;
int range(int low, int high);
[Code] .....
When the number is guessed correctly the program doesn't print "You guessed right" ....
Code:
#include"stdafx.h"
#include<iostream>
#include<cstdlib>
#include<ctime>
#include<string>
usingnamespace std;

I have a program that generates random numbers. After the random number is generated, the program asks if you want to generate another random number. However, if you generate another random number, it is always the same as the first random number. How can I fix this?
View 5 Replies View RelatedI'm trying to generate random numbers so that I can assign people to teams. So far I have come up with this
Code:
int generateTeam(){
int i, teamNumber, c, n;
for (c = 0; c <= 5; c++) {
n = rand()%100 + 1;
}
[code]....
}//end generateTeam I'm not sure how to make it so that I can exclude the previous random number when generating the next one. As an example, I have 22 students and I get the number 19. Now I can't have 19 again because that guy already has it.
I'm trying to write a program that generates a random number between 50 and 200. I made a program that generates random numbers, but how to make those random numbers be in-between 50 and 200. Any example of a program that generates random numbers that are confined in-between certain values?
View 1 Replies View RelatedWhat I'm trying to do is to have the program pick random people for different jobs. The user enters the number of people, then, enters both jobs and the people's names. I need the program to pick random people, but randomly pick again if the person has already been picked, so, no repeats. I have the program picking random people, but I can't get it to not pick the person again. I'll run it and there will be no errors, but it's almost like Xcode completely bi-passes the for/if to check if it's picked the person already.
Below is the code.
#include <iostream>
#include <math.h>
using namespace std;
int main() {
int runagain=0, correctnames=0, versiondesciosion=0, correctjobs=0;//vars that make descisions for running again

Dont look at the "fun" version for the switch statement. It's not ready yet, I'm just having trouble with the random thing.
//VALID:
const int CONSTANT=100;
int integerArray[CONSTANT]={ 0 };
//but after getting input let's say:
cin>>randomInteger;
int integerArray[randomInteger]; // This is invalid.
// VISUAL STUDIO 13 Says : randomInteger must be a constant; If so?
const int CONSTANT=randomInteger; //This is also invalid.
How to get user defined
//Input in a constant variable?
How to resolve this? I know dynamically allocation other than this.
I am using VISUAL STUDIO 13 ....
Ok so Im suppose to make this program were the user inputs the size of the array then the user sets a certain range min and max for random numbers to be generated. I have a function named fillarray()
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
int fillarray();
[Code] ....
Whenever i run the program i keep on getting a loop for the size of the array.
I want to generate big random numbers in C(not C++ please).By "big" I mean integers much bigger than srand(time(NULL)) and rand() functions' limit(32767).
I tried writing: (note:I am not able to see "code" tag button in this editor,so I am not using it)
//****
int randomnumber;
srand( time(NULL) );
randomnumber = (( rand() % 33 ) * ( rand() % 33 ) * ( rand() % 33) * ( rand() * 33) * (rand() % 33 )) + 1
//****
But I have doubts about it's randomness quality.Also there is another problem,the program can't know the maximum random number it should use before user input,so maximum random number may need to use much smaller maximum random number according to user input.
Is there a better algorithm to create big random numbers in C?
I'm trying to use a random response generator. I found a ton of information on this site, and I'm running a (very simple) program that is using 5 responses. My issue is, that every time I run the program (debug in visual express), it generates the same responses, in the same order, every time.
