if there is a spinwheel that has 20 or so numbers. can spin the wheel until stops and that is the number to use.
how to make a program that picks a number like spinning a wheel. could make the wheel pick numerous random numbers each revolution or one number per revolution
say until 9 or so are chosen
be good if program could work however many numbers are to be chosen from
I got this code here id like for it to pick up a random word from a text file and use it as the nick in this line
Code:

How could i do it heres the full code for the client

I'm having some problems with changing an array of numbers of type char to type int. Every time i try to sum 2 array indexed values it returns some letter or symbol. Also, if i change the type of the array in the functions the compiler gives me an error message. I would also like to add that the problem requires that the first two arrays be char so each individual number gets assigned to a different value.
My current code is:
Code:
#include <iostream>
void input(char a[], char b[], int& size_a, int& size_b);
void convert(char a[], int size);
void reverse(char a[], int size);
void add(char a[], char b[], int c[], int size);
int main()

I have recently looked into a self created project where I wanted to compare user input against a list of strings in an external file. That has since been completed to my great satisfaction, however it did throw up some interesting issues in my knowledge and understanding of user input..What is the best way to pick up user input i.e scanf,stdin etc. and when should either be used and can a mixture of types be used, and if so, when and why.
A quick program to take different input methods and display differnt output method (obviously corresponding i.e scanf/printf - fgets/fputs)
My first pothole came when I have setup the method for scanf - fine. Then I setup the method for fgets(test,100,stdin) for example and the fgets method no longer picks up stdin from the user..

#include <iostream>
#include <type_traits>
template<typename T, typename = void>
struct Test {
static int constexpr value = 1;

Why does it output 1 instead of 2? How can I make it output 2 and still output 1 for e.g. Test<double>::value?
I'm using the Bullet physics library in my program and am currently trying to implement picking. The way the world is currently set up, there is a terrain with a box on top of it. Whenever I click on the box, my program only registers that the terrain has been clicked and doesn't recognize that the box has been clicked.
void PhysicsEngine::RayTest() {
vec2 Mouse = MOUSE_POSITION;
Mouse.y = WINDOW_DIMENSIONS.y - Mouse.y;
vec4 RayStart = vec4(2*Mouse.x/WINDOW_DIMENSIONS.x - 1,2*Mouse.y/WINDOW_DIMENSIONS.y - 1, -1, 1);
vec4 RayEnd = RayStart; RayEnd.z = 0;

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] .....
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.
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 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?

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
Code: #include <iostream>
#include <string>
#include <iomanip>
#include <ctime>
#include <fstream>
#include <cstdlib>

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:
Code:
#include <random>
typedef std::uniform_real_distribution<double> distr_uni;
#define max_threads 1
using namespace std;
[Code] ....
When I set max_threads=1 I get 50027, but when max_threads=60 (on a machine that supports it....) I get 50440.
The sensitive RNG and its engine I have declared within the parallelized area, so it's not really clear to me where the error can possibly be.
Looking for error that is apparently there?
