I tryed to create program I wich u can guess number, I made some if to prevent inputting 2 times the same number It works. I tryed to apply the same process for generating
#include <cstdlib>
#include <iostream>
#include <stdlib.h>

The code below will generate combinations of numbers from 1 to 25 in an 15 numbers array. The only filter I've applied is that the sum of all the numbers in the vectors divided by 15 needs to be between 13 and 14.
I would like to count how many consecutive numbers there are in one combination, so that later i can apply another filter.. for example:
1 3 4 5 6 8 10 13 14 16 17 18 19 20 25
3 + 4 = 1
4 + 5 = 1
5 + 6 = 1
13 + 14 = 1
16 + 17 = 1
17 + 18 = 1
18 + 19 = 1
19 + 20 = 1
_____________
Count = 8, in this case..
I think it's not very difficult to do, but i just can't see how to do it.
#include <iostream>
#include <vector>

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.
Given a number "n" supplied by the user, write all the prime numbers less than or equal to "n"
not at all how to make the number I enter me for the numbers that I need even a couple makes the prime number if the command is used repeat for but and decision making but the truth is that I can think of no way to do for this exercise is that the prime numbers are those numbers which are divided only by 1 and themselves also
until the moment I have this code
#include <stdio.h>
#include <stdlib.h>
main(){
int n;
n=0;
printf("enter the desired number: ");
scanf("%f",&n);
system("pause");
}
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 am trying to generate 3 random numbers between 1 and 6 using a function called generate_rand. but everytime im having an error : no oprators "<<" matches these operands and the last error was :end of file found before the left brace
my program is the following :
# include<iostream>
#include<cstdlib>
using namespace std;
[Code]....
srand (time(NULL));
for(int i=0; i<N; i++) {
points[i].x=(rand()%(32767-(-32767)))+(-32767);
points[i].y=(rand()%(32767-(-32767)))+(-32767);
cout<<"x="<<points[i].x<<endl;
cout<<"y="<<points[i].y<<endl;
}
Im trying to generate random numbers between -32767 and +32767, where im going wrong, this code generates only negative numbers
I am a C++ beginner with no programming background. I need to write a lottery program that generate 5 non-duplicate numbers between 1 and 20. Here is my code and it just wont work.
#include <iostream>
#include <stdlib.h>
#include <time.h>
#include <iomanip>
using namespace std;
int main() {
srand(time(NULL));
int lottery[5] = { 0, 0, 0, 0, 0 }, count = 0, rand_lottery;

So, there has got to be an easier way to generate random numbers within a specific range. Here is the code that I have been using, for a range of 1-6:
#include <iostream>
#include <ctime>
#include <cstdlib>
using namespace std;
[Code]....
My program generates an array of random numbers. I want to then search a specific number within the array. If the number is in the array then a message apopears on the console saying that its there. I'm using the binary search algorithm to do this.
#include <iostream>
#include <ctime>
#include <cstdlib>
#include <iomanip>
#include <cstring>
using namespace std;
int size;
int getSize() { return size; }

I am trying to generate a random number between two numbers that the user gives me.

I'm trying to write a code which will generate numbers for a binomial coefficient from a number interval [2-10], i think it should look like this:
n=2
r=2
n=2
r=3
n=2
r=4
n=2
r=5
.
.
.
n=10
r=10
-The program should stop here.
This is badly written, but it still has the basic idea in it.
#include <iostream>
using namespace std;
int main () {
int n=2;
int r=1;
[Code] ....
I have made the following code to illustrate my problem:
#pragma once
#include <bitset>
#include <iostream>
[Code].....
Now I want to avoid my bitset field being constructed before the ConstructTest constructor is called. So at first I tried wrapping it in a unique_ptr but found out that this would give me some potential problems with const functions.
And then I realized I could just set it to NULL, as I have in the above code. I tried that, got unexpected print outs, until I found out that NULL is just equal to 0 in C++ and that the bitset has a = operator that takes a number, int, long or maybe something else. Either way, this effectively constructs the bitset and sets it to the number 0.
So my efforts so far have been shut down. But then how can I avoid the bitset being constructed in advance, if at all possible?

View 3 Replies View RelatedI was investigating for the first time how to generate prime numbers with a considerably high upper limit, around 10^6 or so. I read about sieve's algorithm and tried to implement it using c#, as I had previously brute forced the generation. In Sieve's algorithm, instead of marking the values that were not prime I simply eliminated them, but I don't think that would make any difference. The issue is that my implementation of sieve's algorithm must be wrong, as when I establish the limit as 10^5 I get the following output:
Brute force:
Computation time: 00:00:00.0643539
Sieve's algorithm:
Computation time: 00:00:20:6934223
I have already checked that their generation of primes is correct, but I do not know why one is significantly slower than the other. Here is my code.

I have been writing a program to generate pairs of RSA keys using small prime numbers. I have been using mpz_invert() to get a value for d for the private key. On small prime numbers it calculates the correct value, but on larger primes it calculates incorrect values.
I'm assuming there must be an upper limit to the values the mpz_invert() function can handle? If so, what is this limit to avoid erroneous values?
I've just started working on a Database application and maintaining a previous developer's code, one thing I see is that column and table names are hardcoded throughout the code which is something I'd like to avoid. To me it seems like a practice that is prone to spelling mistakes reaping havoc across the application.
Some I've looked at include:
Constant strings
const string TableName_ColumnName = "TestName";
Dictionary and Enum:
public static string GetColumnName(ColumnId inColId)
{
[Code]....
I think I prefer the second option but it means that retrieving the column names means quite a long winded function call.
how to handle reallocation costs when input data is unbounded.
For instance, in a low-latency environment such as a trading platform or real-time data collection system or MMORPG where you can receive a large amount of input, you can not afford a stall while the data structure is rebuilt with a larger buffer. You can use historical data to "guess" an appropriate size but this is far from fool-proof. You can also create a sentinel thread that monitors the load factor of your data structure but that brings its own problems (e.g. another thread that needs execution time and to lock the data).
I am just starting out programming and have an assignment due in the near future. the problem is I cant seem to figure it out. I started it already but got stuck cant seem to figure it out. Here is the assignment.
Create a program that will generate a list of 200 random numbers (ranging from 1-1000) and determine the medium, mode, and average of the list of numbers. Have the program display the original list ant then display the list in ascending and descending order on the screen.
So I've actually used rand() happily without any problems so far, but now I faced a problem. I have an AI loop that initialized a random number between 1 and 2 at the beginning, so something like this:
while (condition) {
int random = rand()% 1 + 2;
if (random == 1) {
[Code] ....
So this doesn't really work since it doesn't actually assign a new random value. I came across srand(time(NULL)), which resets the seed, but I didn't quite get when to use it. Do I have to call it in every cycle of the loop? I'm not completely sure how this works.
I saw a program in which it uses rand like this:-
d1=rand() % 6+ 1;
where, d1 is any integer. The program is to simulate the roll of a dice. The whole program is this:-
Code:
#include<stdio.h>
#include<stdlib.h>
main() {
int i;
int d1, d2;
int a[13];
[Code] .....
So I have an object of class NRG (Normal Rand Generator) which takes, as an argument to it's constructor, an object of class RG (Rand generator).
template<typename RG>
class NRG {
RG rg;
public:
NRG(RG r):rg(r){}
double operator()();
An object of this class will return a normal random when it's member function operator()() is called:
template<typename RG>
double class NRG::operator()() {
static int flag = 0;
static double N2 = 0.0;
if(flag==0)
[Code] ....
However, when I run this I get an error which says:
C:UsersavadhootDesktopb.cpp|69|error: 'template<class RG> class NRG' used without template parameters|
C:UsersavadhootDesktopb.cpp|69|error: expected identifier before 'operator'|

Basically I'm supposed to use a while loop to generate a random number and use a switch statement to output the appropriate information. I feel like I'm missing a few things that are very simple.

I'm writing a program with two classes, one that contains a card's rank and suit and the other contains pile of these cards. I'm having trouble when it comes to adding a pile to another pile...here's what I have so far:
class Card //Card class declaration
{
private:
int rank; //invoking rank
char suit; //invoking suit
public:
void setCard(int r,char s); //determines card suit/rank
[Code] ....
I understand that I'm calling my pile arrays incorrectly, but I'm not sure why.
I am a very very beginner at programming with C. Well, basically i have to generate a real number between 0 and 1 (which as the same as from 0 to 100 k and than dividing everything with 100 k).
Why I am constantly talking about 100 k? Because I would need approx 50 000 random numbers between 0 and 1. My code currently looks something like this:
Code:
int main(int argc, char** argv) { int min,max;
double number;
srand((unsigned)time(NULL));
number = 1 + rand()%100;
printf("The number is: %lf",number);
sleep(2);
return (EXIT_SUCCESS);
}
And If I am not mistaken, should generate numbers between 0 and 100. But I can't figure it out how to change to code in order to get enough numbers.
Using loops that would generate the same results. I need to use a loop that would make the syntax less lengthy ....
Code:
#define _CRT_SECURE_NO_WARNINGS
#include<stdio.h>
#include<iostream>
float check(float s);
void load(float*);
