C/C++ :: Lottery Program That Generate 5 Different Numbers Between 1 And 20
Nov 4, 2014
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;
I need to write a lottery program that generate 5 non duplicate number between 1-20. Below is my code and it said my [i] is undefined and it is an undeclare identifier.
#include <iostream> #include <stdlib.h> #include <time.h> #include <iomanip> using namespace std; int main(){ srand(time(NULL));
Write a function named generateLotteryNumbers. The function is passed an int array of size 5. The function should generate 5 different lottery numbers in the range 1 to 50 inclusive and place the numbers in the array. The declaration is as follows:
Note that no data is passed in to the function. The array is used to return the function results. Thus the parameter is an OUT parameter. Do not display the result. Return the result.
Do not seed the random number generator inside the function. If you seed the random number generator inside the function and the function is called many times in the same second, your function will return the same results each time it is called.
I know how to generate the numbers in the specified range but I do not know how to test for duplicates. Here is the code I have so far:
Code: //This program will test the "generateLotteryNumbers" function #include <iostream> #include <cstdlib> #include <ctime> using namespace std; void generateLotteryNumbers (int lotteryNumbers[]);
[Code] ....
When I try to compile this, my compiler tells me that lines 41 and 46 require an array or pointer type.
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?
Suppose you want to develop a program to play lottery. The program randomly generates a Lottery of a three-digit number( any number from 100 to 999), prompts the user to enter a three-digit number, and determines whether the user wins according to the following rule:
1. If the user matches the lottery in exact order , the awards is $100,000. 2. If the user input matches the lottery digits, the awards is $50,000. 3. If two digit in the user input matches a digit in the lottery, the awards is $30,000. 4. If one digit in the user input matches a digit in the lottery, the awards is $10,000.
Sample: The winning number is 865.
Your ticket is 865 then 100000 Your tickect is 686, or 568,.. all digits are right but not in order You get 50000 Your ticket is 860, or 186 .. then 30000 Your ticket is 800, 706, 600.. just one digit much you get 10000 Else 0
Im using if/else statements. Which syntax would I use to figure out the limit between 100-99?
I have an a problem I need to make lottery random generation program what asks from user how many lines to gerenate random numbers. But i am now stuck.
Console.WriteLine(" choose how many numbers "); int i = int.Parse(Console.ReadLine()); Random randomizer = new Random(); for(int j = 0; j < 7; j++) { i = randomizer.Next(1, 39); } Console.WriteLine("Your random numbers are{0}", i); Console.ReadLine();
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:
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
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;
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
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 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:
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'm creating a program that generates random sentences with structs..I'm trying to use structs and and create 4 different groupings article, noun, verb, and preposition. Then I'm trying to use "r = rand() % ;" to randomly pick one one word from each group to make a sentence. this is what i have
Code:
typedef enum article { the = 1, a, one, some, any } article; typedef enum noun { boy = 1, girl, dog, town, car }
Problem: Write a program to generate a calendar for a year. The program should accept the year and the day of the week for January 1 of that year (0 = Sunday, 1 = Monday, etc.). The calendar should be printed in the following form:
I have wrote code that has three functions, one to print the month, one to print the days in month, and one to find if it is a leap year or not. I have gotten up to the point where I can print the 12 months with a for loop, but how to print out the days in the format above.
This is my code.
#include <iostream> using namespace std; void printOneMonth(int month, int& dow, int year); void daysInMonth(int month, int year, int& dim); bool isLeapYear(int year); int main(){ int year=0, dow, count;
