I'm looking to code a completely random distribution of numbers that doesn't affect performance using rand. I believe this code would be ideal but I don't understand how to use it. Where would I input the range of numbers and the quantity?
double uniform_deviate ( int seed ){
return seed * ( 1.0 / ( RAND_MAX + 1.0 ) );
} int r = M + uniform_deviate ( rand() ) * ( N - M );
Write a function that generates 1000 normally distributed (Gaussian Probability Distribution) random numbers. Range should be between -3 and +3. Numbers should be double floating point.
There's more to it than that, but I've got it from there.
I wrote the following program shown below that produces a normally distributed random number several times, and then takes the average of them. The problem that I have been having though is that the output it has been producing is 0.0288385 despite the fact that I set the mean of the normal distribution to be 0.1. Why this output value would be so far off from 0.1 despite having averaged over such a large number of random numbers namely 10,000 of them? Also, how to randomly seed this random number generator such that it gives a different value each time its run perhaps by seeding it with the windows timer? Below is the program.
#include <iostream> #include <random> using namespace std; int main() { default_random_engine generator; normal_distribution<double> distribution1(0.1,3.0); double number1,sum,n;
Create a program that finds all numbers in an array that show up exactly 5 times. I am trying to solve this issue by making a frequency distribution via two loops and two arrays, but I am having trouble getting my loop to not recount a number it has already counted.
For example, if you enter ten 1's into the "entered Numbers" array I want it to store a count of 10 in frequencyarray[1]. Instead it is storing
In my program I have to load a page in a second window based on user's decision. This is how I do it:
case 1: Page1 p1 = new Page1(); secondwindow.frame.Source = new Uri("p1.xaml", UriKind.Relative); secondwindow.Show(); break; case 2: Page2 p2 = new Page2(); secondwindow.frame.Source = new Uri("p2.xaml", UriKind.Relative); secondwindow.Show(); break;
The user should not be able to navigate between these two pages, and between choosing one or the other page, the user will have some interaction with the main window. For the user interaction with the main window, the second window gets hidden:
if (secondWindow != null) { secondwindow.Hide(); }
Now if the user selects the first page and and then the second page, when I show the second window, I can see the first page for a fraction of a second, and then second page gets rendered. I wanted to know if there is a way to make sure the rendering is complete before using:
I am doing a messaging application using Visual C++ window form application.
Sometimes I can't receive a whole message from the sender. If i type short sentence like "123456", it can be shown properly. But, if i type a quite long sentence like "123456789123456789", it can't shown a correct message, can't show exactly the whole message.
here is my code:
//transmission: String^ message; String^ message1; String^ name = this->serialPort1->PortName;
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);
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?
I'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.
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)
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 am designing a math program for kids. I want the program to produce 2 random numbers and check the sum of these numbers against the user's guess. I have the generating random numbers portion complete. What's the coding procedure to compare the sum to the user's guess?
Assuming you have an array of these values x=[16,18,23,24,39,40] how would you write a function to generate random numbers that can add up to a 100? I need to know how many random numbers can add up to a 100.
This is my program i have to choose for random number between 1-25 and display them the program works perfectly just that every time i run its always the same numbers.
#include <iostream> #include <cstdlib> // include library to use rand using namespace std; int main(){ int winner1; // declare variables int winner2;
i wrote this code but don't know if the numbers i array for p will generate in that order. how to get 5 random numbers horizontally and insure that 7,15, 22,27,31 will not generate in that exact sequence?
#include <iostream> #include <stdio.h> #include <stdlib.h> #include <conio.h> #include <stdio.h> #include <time.h> using namespace std; int main() {

The program is to generate random numbers to a file and will have one integer parameter, Open a file and then using a loop write the required number of random numbers to the file. Scale the random numbers from 1 and 100 inclusive. Then closes the file .The last function will read the numbers in the file into your program. so far i have
I generate a series of random numbers in parallel (using OpenMP), but depending on what number of threads I invoke, I get a different result. From that I conclude that I have made an error somewhere!
Here is the MWE, which generates a number between 0..1 and increments a variable if the generated variable is larger than 0.5:
i'm trying to fill an array with random numbers and then sort them via bubblesort. it seems to work so far. the problem is, that i seem to get the same numbers for the same input. somehow the randomness isn't working.
Code:
#include <stdio.h> #include <stdlib.h> int main() { int a, b, c, d, e, f; }
