i want to create an arry with random value. in 50% times the average of this array is upper of 0.5 and in 50% times the average of this array is lower of 0.5 . i want to write this code in C++. but i dont know what the algorithm is.
My code is this.
#include <algorithm>
#include <cstdlib>
#include <iostream>
int main() {
int a[10] = {0, 1, 2, 3, 4, 5, 6, 7,8 ,9};
std::srand(unsigned(std::time(0)));
}
Write a program that generates an array of 20 random numbers between 1 and 100. Use a loop to output the numbers on the screen with a field width of 4 characters. Write code that will reverse the numbers in the array and then output the numbers to the screen with a copy of the same output loop used with the original numbers.

How to generate random and different number in a range. This is my code:
Code:
#include <stdio.h>#define n 8
#define m 7
int main() {
int i,j,a[n][n];
printf("Relaxed Latin Square (%d,%d)
[Code] .....
When I executed that code, the number is random but not different.
Code:
for(int i = 0 ; i < SIZE ; i ++)
{
scanf("%d" , & selection[i]);
srand((unsigned) time(&t));
draw[i] = rand() % 50; //feeling could be a problem with this line of code :::::
}
is it possible to do this. i am trying to get 6 different numbers stored into 6 elements of an array . this is the piece of the code i think there is a problem with. ie my program scans the numbers and then crashes at this point so think it could be something to do with the commented line?
I have to write a program that selects a random color from an array. I used the srand (time(0)); statement but it still gives me the same color each time. Here is my code.
// Color.cpp

using namespace std;
#include <string>
#include <cstdlib>
#include "Color.h"

The program has two array of character. One of them has size 26 and is initialized with the alphabet a to z. A random number generator generates two numbers and these two numbers are used to index into this array of alphabets. The second array is used to hold the indexed alphabets. For example, the first row is the value held in the second array and the second row are the two generated numbers.
b g c z k e <- letter index by generate number n1=1 n2=6 n1=2 n2=25 n1=10 … … … … n2=4 <- generated n1 & n2
Please see illustration below for clarification on the above question.
Element a b c ……… x y z
Index 0 1 2 ……… 23 24 25
Array2
Element a b c ……… x y z
Index 0 1 2 ……… 23 24 25
Final state after program execution
Array1
Element a b c ……… x y z
Index 0 1 2 ……… 23 24 25
Array2*
Element c e m ……… z f g
Index 0 1 2 ……… 23 24 25
Random No generated 2 4 12 ……… 25 5 6
* Actual char element allocated to each index location will depend on corresponding random number generated. Program completes execution after filling all 26 locations in Array2.
Basically we have this 7 bit binary code, and i would like to pick out 3 numbers randomly from it, how do we do that ?
for example 1011101
int Num[7];
for(int i=6; i>=0 ; i--)
{Num[i] = binary % 2;
binary = binary/10;}
I'm currently working on assignment which requires to generate a random permutation of the first N integers. For example, if N = 4, one possible answer is {3,1,2,4} without duplicates. {3,3,2,4} is not correct
to fill a[4], generate random numbers until you get one that is not already in a[0], a[1], ..., a[n-1]. for a[0] whatever random number you generate can be put in it. So here is my code. It seem to works but sometime it give duplicates.

I'm currently working on a code, its a wheel of fortune type of game. I have specific values of an array of size 10, and i have to get these at a random. so they would not print out in order. but how to assign each value of the random to the array.
#include <stdlib.h>
#include <stdlib.h>
#define CHANCES 5
int main(void){
int num, i;
int money[10] = { 100, 300, 200, 350, 250, 150, 175, 500, 50, 75 };

I need to select a random item from an array but I am going to have more than 1 such array so I created the random value selector as different function. Right now I am getting a correct value for random function but when I try to access the array value associated with that index I get 2 digits which does not make any sense.
#include <iostream>
#include <cmath>
#include <ctime>
using namespace std;
int randFunction(int size);
int main() {
int heapsize;

I need to finish this program which has to ask for seed, then the user gives 5 friends, and then it will choose who to text randomly and show who did not make the cut.
This all i have, I am stuck and I do not know if it correct.

#include <string>
using namespace std;
int main() {
string num_friends[5];
int user_input;

So we're having an assignment for school where you code a Roulette game which simulates you playing and you can choose how many times you "play" to check how many times you'd win (if that makes any sense, im german :P)
Anyways, the problem is how do i store all the random generated numbers in an array while NOT doing this (it's just a snip):
Code:
void randomzahl(void){
int i;
int zahl5[5];
int zahl10[10];
int zahl100[100];
int zahl1000[1000];
int zahl10000[10000];
if(runden == 5)

i have a programming problem and i am unsure of what the final part is.the question is:
Write a program that fills an array with 10 random numbers between 1 and 20, displays the 10 numbers, and finds the sum of the 10 numbers. Call the getData, displayData, and getSum functions from the main function. Output the sum from the main program by calling the getSum function within a printf statement.
i am just really unsure of what this is--getData, displayData, and getSum functions from the main function. Output the sum from the main program by calling the getSum function within a printf statement.what i have got so far is;
Code:
#include <stdio.h>
#include <stdlib.h>
#define ARY_SIZE 10
int main() {
int randomNumbers[ARY_SIZE], sum = 0, i;
[Code]....
How would i go about loading an array with random numbers with in a range. For example, loading an array of 500 elements with random numbers in the range of 50-100.

At the end in the 4 lines some of the names, actions and locations repeat. How do I make them to not repeat and use every name that you will enter? do I need random_shuffle? How can I integrate it in my code?
Below is my code for a program that is suppose to generate and display six unique random numbers (between 1 and 54). The issue seems to be in my check for duplicates. I know what I am doing wrong but can't seem to find a way to fix it. I think it is getting stuck in an endless loop because the way I have written it looks like it checks the first value against itself which will of course look like a duplicate everytime.

I am a very fresh c programme user, and need to fscanf data to arrays. Somehow it just doesn't gets recorded, wonder what is wrong with my code?
When I printf the array it always ends up with random numbers. Below is my programme which is just designed to read a doc and print it back out, as well as the text doc it is designed to read.
I am trying to sort an array of random numbers by passing it to a method Sort(), sort the array, and then pass the entire array back to the calling program. Each time I run this though, the array doesn't seem to sort. I'm not sure if the problem lies with my sorting algorithm or if it has something to do with calling the function.

static void HighAverage(int[] a) {

The thing is, The first 2 rows having 7 columns like this:
0000000
0000000
User gives an input of seats reserved, for example user inputs 3 seats, then the program should give output like:
1110000
0000000
I will not ask any specific seat but put assign seats randomly where available.. How to do it?
