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;

The user thinks of a number from 0 to 100 and the program tries to guess it. The problem is, I'm new to random numbers and use a function to generate them that isn't my own. It generates the same numbers each time the program runs, here are screen shots:
Run 1: [URL] .....
Run 2: [URL] .....
I read something about seeding or something, if I need it, must don't give me the answer. If you have the liberty of time explain more to me about the random business.
Here is my code:
#include <iostream>
#include <cstdlib>
#include <iomanip>
#include <unistd.h>
#include <string>
#include <ctime>
using namespace std;
int rand_lim(int limit) {
[Code] ....
one of my project involves loop inside loops and creating random numbers. Here is what I have so far:#include <iostream>
#include <string>
#include <cstdlib>
#include <ctime>
[Code]....
so the program will create a random value for the inflow. The idea is that the internal for loop will continue to run until the fill_level of the reservoir, which starts at 0, hits the capacity. The process of simulating how many years (each iteration of the internal for loop representing a year) is to be repeated 10 times by the parent for loop of the water_level simulation for loop.
The problem is that the random number that is supposed to created are the same number. THey are different every time I run it, but they are the same every time the loops repeat to make a new simulation.
I want to make 10 random numbers thus making 10 random flips of a coin. I am getting 10 tails or 10 heads!
Code: #include <iostream>
#include <ctime>
#include <cstdlib>
using namespace std;
int main(int argc, const char * argv[])
{
[Code].....
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

I am reading certain int's at a time from one int number stored in a file. I'll explain. I am working on an ezpass project and basically I have to store an int in a file, and from that file, write a program that separates numbers into information.
For example:
the number 204601324 is stored in a file. I know how to open a file from terminal, but the issue is reading the individual numbers. The first number is weight class (2). My program has to display that number as the Variable "weightClass." how do I get it to do that? In addition, miles allowed is the number "0460." How do I get that number to display as the variable "oMiles?"
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?

How do i make the srand() function make new numbers every time i call it? Now it seems like it repeats its result over an over again.
Below is a program that should generate random numbers for 3 dices and print these out. But it prints out the same nr over and over.
Code:
#include <stdio.h>
#define MAX 100
int filler(int dice1[MAX], int dice2[MAX], int dice3[MAX]) {
int throws, nr;
printf("Define the number of throws");
scanf("%d", &kast);

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?
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.

int main() {
int a, b, c, d, e, f;

I have the random values down but when I try to assign randValue to another integer I get an error.I want to make an inner loop where I find 5 random number 50 times and print the average of those numbers.
I know I have the bare bones of the below, but without giving me a huge shove in the right direction can I have a poke? I have been programing for three months now. I have noticed when I do simple fun projects I learn more then what my professor assigned to me. The class is over but I want to keep building.C++ starts in one week...
Code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define NUMBERS 5
int main(int argc, const char * argv[]) {
float randValue = 0.0;
int i;
[code]....
Inside my loop is this
srand(time(NULL))
a=rand()%10;
So it will generate numbers again and again as the loop goes on but it always repeat some numbers. My question is, how would you generate numbers without repeating? Somebody told me that i have to use auto increment, but i really have no idea about that.
