C/C++ :: Remove Repeating Numbers In Array?
Nov 14, 2014
Question was:
QuoteWrite a program that reads in ten numbers and displays distinct numbers. If a number appears multiple times, it is displayed only once.For example: if user enters 1,1,2,3,4,4,5,1,0,9. You should output: 1,2,3,4,5,0,9. Order doesn't matter.
Steps:
a. Create an int[] to hold all the integers of user input and another int[] to store the distinct numbers.
b. Make a nested for-loops which the outer loop goes though the first array and inner loop to check if the value is already inside. Store the value to the second array if new number,otherwise do nothing.
c. Make a for loop to print out the elements of the second array

Well I've given myself a lil project and I can't seem to figure out why the numbers keep repeating. What is the cause of this repetition. the function that generate the numbers is below
Code:
void numGen(struct Ticket *pick){
int x;
int y;
int check = 0;

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.

I want to a C program to delete an element from an array which can use both index method & character method
For example
input : "1 222 333 4444"
output:"1 22 333 4444"
if either index = "4" or character ="2" is entered
It should able to read in/accept any input array of varying length, and the position/index or element in array to be deleted...

I was wondering if there was a way to set up a code with an array of variable dimensions that removed random points on that array i.e.
1111
1111
1111
then randomly remove a point:
1101
1111
1111
and then be able to repeat this process until all points are removed.

So I am currently working on a program that will remove elements from an array. Suppose I had a 3x3 Array
1 2 3
4 5 6
7 8 9
and chose the element 5 as the one I wanted to remove. How would I do that? This is where I am so far.
#include <iostream>
#include <stdlib.h>
#include <cmath>
#include <time.h>
#include <algorithm>
#include <vector>
using namespace std;

I'm currently trying to remove the first element in an int array using objects in C#. I have just coded how to add an element to that start of the array and though it was just a case of changing a few things.
Here's the code for the addFirst() but i can't for the life of me figure out removeFirst()
public void addFirst(int value) {
if (isFull()) {
throw new Exception("List full");

The goal is to merge two files of names, sort them and remove duplicates.I've managed to merge the two files into a single char array and sort them with a function so they are alphabetical.I'm having problems removing the duplicate entries from the array. Here is my code:
Code:
#include <stdio.h>
#include <string.h>
#define NUMSTR 10
#define STRLNG 9

I am working with cart algorithm and i have the following problem,i need to try all possible splits of n values in order to determine the best.
So lets say i have 3 values("low","medium",high) then the possible splits(pairs) would be:
(assuming low=0,medium=1,high=2)
0,1-2 low,medium-high
1,0-2 medium,low-high
2,1-0 high,medium-low
For 4 values(a,b,c,d) it would be:
ab,cd
ac,bd
ad,bc
abc,d
adb,c
adc,b
bcd,a
Problem is i dont know n so the solution must be recursive. The possible splits are 2^(n-1)-1. I am really stuck and most of the code is complete for cart and i really don't want to restrict it to binary values.

So I wanted to make a program which randomizes a list letters or something without repeating the letters like I get here:
Code:
#include <iostream>
#include <string>
#include <stdio.h> /* printf, scanf, puts, NULL */
#include <stdlib.h> /* srand, rand */
#include <time.h> /* time */
int main () {
using std::cout;
using std::cin;
using std::string;

I am having a issues with an assignment in my class and don't really understand why. I am getting undeclared identifier errors even though I have declared and I am also getting an error. Here is the code:
#include "stdafx.h"
#include <iostream>
#include <cassert>
[Code].....
Last time I came to you all with an error it was a simple brain fart on my part but I don't think this one is like that. I would love to tell you what the program is supposed to do but I still do not really know, which might be part of the problem. I guess it outputs different sized rectangles...

I have two arrays:
const char *mymp3list[15] = { "Song 1", "Song 2", "Song 3", "Song 4", "Song 5", "Song 6", "Song 7", "Song 8", "Song 9", "Song 10", "Song 11", "Song 12", "Song 13", "Song 14", "Song 15" };
const char *myFriendsmp3list[20] = { "Song 1", "Song 2", "Song 3", "Song 4", "Song 5", "Song 6", "Song 7", "Song 8", "Song 9", "Song 10", "Song 11", "Song 12", "Song 13", "Song 14", "Song 15", "Song 16", "Song 17", "Song 18", "Song 19", "Song 20"};
And I want to compare the two arrays and print out a list of all the "songs" without repeating any.
I've figured out how to print the just the duplicates using:
for (int count = 0; count < SIZE1; count++){
for (int i = 0; i < SIZE2; i++){
if (mysonglist[count] == friendsonglist[i])
cout << mysonglist[count] << "";
}
}
But I'm stumped on how to print a full list containing no duplicates.

Find all the prime numbers between a given pair of numbers. Numbers should be read in from an input file called "numbers.txt" and find all the prime numbers between them. Store the prime numbers in an array, then sort the array from greatest to least. Display the array before and after the sort.
I'm stuck on how to put the prime numbers into an array.
The input file has the numbers 1 & 100.
Here's what I have so far.
#include <iostream>
#include <fstream>
using namespace std;
int main() {
ifstream fin;
fin.open("numbers.txt");

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>
#include <numeric>
