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;
[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.
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

i want to write a c++ program to build min heap which gets above values from user. remember this program should not alloduplicate values to enter. it should discard duplicate values.
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;

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.
I have been given an assignment to make a code to read some text nd display all the words nd the number of times they appear in another file or as output without displaying the repeating words. I made the code but its not giving any output.

User enters sentence "The Smiths have two daughters, three sons, two cats and one dog." (The numbers may change depending on what the user chooses to enter. He told us the range would be from zero to nine.) and we have to convert the written numbers within the sentence into actual decimal numbers and print out the new sentence. Ex. The Smiths have 2 daughters, 3 sons...etc.
I have written the following bit of code which reads the string and finds all the "written numbers" but I am not sure how to proceed from there. I am stuck on how to print out the new sentence with the converted numbers as my professor mentioned something about creating the new string using dynamic memory allocation.
Code:
#include <stdio.h>#include <string.h>
int main () {
char A[100];
int length = 0;

ignoring negative numbers when I am trying to add up only positive numbers.

I need a list generated of all possible subset combinations for the set 1,2,3,4,5,6,7,8,9,10,12. Select six. Numbers cannot repeat.
Example subset: 1,2,3,4,5,6 (six selected, no repeats).
Example of what I dont need: 1,1,2,2,3,3,4,4,5,5,12,12 or 1,1,1,1,1,6.
I will also need the opposites removed, meaning...if I have 1,3,5,7,9,11 then I need 2,4,6,8,10,12 eliminated from the final list.
This is for a game, where you must select all numbers right or no numbers right.
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..

Write a program which reads a stream of numbers from a file, and writes only the positive numbers to a second file. The user should be prompted to enter the names of both the input file and output file in main(), and then main() will open both files. Another function named process() must then be called to read all the numbers from the input file and write the positive numbers to the output file. Note that you must pass the open stream variables for each file as arguments to the process() function, and that you need to (always) double check that the files opened successfully before using them.
This is what I have so far but its not working out!

i have trouble with comparing two of the biggest numbers out of four numbers. Im working on an assigment with a dice game where i need to tell the computer the following;
"if the biggest number out of dice_three and dice_four is the same number as the biggest of dice_two and dice_one, then loop1=true"
this is how i have been writing it so far ;
if
(MAXA(dice_three,dice_four) == MAX(dice_two,dice_one)){
lopp 1=true;
}
(as seen) i am using:
#define MAX(dice_one,dice_two) ( (dice_one) > (dice_two) ? (dice_one) : (dice_two) )
#define MAXA(dice_three,dice_four) ( (dice_three) > (dice_four) ? (dice_three) : (dice_four) )
to calculate which one is the biggest number out of the two pares. The code i have been writing so far seem to have the wrong syntax.
If I have the number 88 how would I add 00 to the end of and turn it into 8800? Bitwise shifts is the only way I can think of to do this but it doesn't work. It completely changes the numbers.
