i am trying to find the max value from a list of 10 values. here i have stored the double values for prices of items in numVal.There are 10 values in numVal i would like to find the max and min value of these numbers. getPrice(1) returns the ten double values.
for(int i = 0; i < store.size(); i++) {
double numVal = this->store[i].getPrice(1);
}
How i can find two equal int in array with O(n) time complexityand O(1) place complexity?

I need to find min value of two decision variables, as far as i know, i should write as a constraint because they are decision variables. "if" statement does not work for decision variables. here is some part of my model in C.
Code:
void TSPMIP(int Scenario, int Agency)

int i,j;

Keep track of the sum of values entered (as well as the smallest and the largest) and the number of values entered. When the loop ends, print the smallest, the largest, the number of values,and the sum of values. Note that to keep the sum, you have to decide on a unit to use for that sum; use cm.

I have a list of integers that i wish to store in some kind of array. However i do not know how many integers are needed to be stored each time i run my program so i therefore cannot define a size for my array.

I have made this program for linked list, but i have one problem with it. I want to make a function that will delete all same values I inuput in the list.
Example: if user inputs 5 I want to delete all 5 for the list. I have tried doing this with the loop inside regular function that erase single value.
This is function that erases single value:
Code:
void list::Delete (int a) {
node *temp=head;
if (temp==NULL)
return ;
if (temp->getNext()==NULL) {

I'd like to be able to just put all of them in ONE type of container, without making multiple lists... Is there any way, using Linq to XML, to maybe add all of these values to a Tuple?
I have a method that traverses a list to compare a number from the list to user input from elsewhere in the program. I have tried a few different things and I am probably overlooking something simple but my problem is my if statement is executing the else statement every run no matter if the input matches. This function is to return the location in the list that the num matches. -1 if no match, 0, 1, 2, otherwise depending on the number of nodes.
int NumberList::find(int num)
{
int temp = 0, count = 0;
ListNode *nodePtr;

I am creating a to-do list application and to store the tasks on the list, I am trying to create a linked list. the code for it so far is as follows:
public class Node //Class for nodes which make up a linked list {
//Declaring the data to be stored in each node and next variable to point to the next node
public string title;
public string description;
public string priority;
public string finish;
public string complete;
[Code] ....
The problem with this arises when I try to create a new node from another class like so:
createForm create = new createForm(); //Creates an object reference to createForm
create.ShowDialog(); //Shows the createTask form for creating a new task
//Declares variables and stores the return value of methods in createForm
string _title = create.getTitle;
[Code] ....
The variables _title etc.. all store values from text boxes as string. However, the code creating the object says the the variables cannot be implicitly converted from type 'string' to 'int'. Why this error is happening??
im using a for loop to find the index values of the tied high scores and store them into string list then reference list in the second for loop to output it to screen however it isnt letting me use an array with index i as an index its self.
void printHighest(Student s[], int length){
int index;
string list[10];//you're never going to have more than 10 people with a tieing highscore.
index = findMax(s, length);
[Code] ....
For the time being I simply removed the idea of string list and just put the contents of the second for loop into the if statement above it. However, I am still curious as to if I can reference an index of an array in an index of another array.
I am grabbing data from three entities and want to grab a field value in each of the entites and place it in an arraylist. What I would like to do is loop through the arraylist for all the values and do something for each value only once. If the value in the array list is repeated, I want to not do anything for it and continue till the end. Basically, I loop through all the values do something for each value and skip over the repeated value if I already did something.
View 1 Replies View RelatedI'm trying to write a debug functions for my application so I can see all the values I like to. My goal is it looks like this:
Code:
void Debug(std::message, ...)
So that I can call it like this:
Code:
Debug("Error: %i, %i", 34, 35);
How I can work with %i, or if there are better solutions. This is what I've so far (not much), just a basic idea:
Code:
void Debug( std::string message, ...) {
va_list list;
va_start(list, message);
??? va_arg(list, ?? );
va_end(list);
// here message should contain everything and be ready for output ?
cout << message << endl;
}
I have problem reading CSV file, i found many solutions but i still got one problem. I need to read CSV file and then these values show in List Control and here i have problem. Idk how to display it in List?

This (2)original list is then to be printed out. The program then uses the algorithm "bubble sort" to (3)order the list in descending order before finally printing it out again.
I have managed to do this but I kind of cheated since I do not quite understand how to manipulate a linked list. What did was I took the values in the linked list and transferred them into an array and then did bubble sort on that array.how to do bubble sort on a linked list as well as how to print a linked list.
Code:
#include<stdio.h>#include<stdlib.h>
typedef struct node
{
int info;
struct node *link;
}Node, *NodePointer;
void printList (NodePointer head)
}

I'm attempting to save values from a char buffer into integer values of a struct.
This is what resides in the buffer "STD 2 2 2 2 2 2 2 " and this is my sscanf call
Code:
sscanf(buffer, "STD %d %d %d %d %d %d %d
", &dt_struct.date,
&dt_struct.mth,
&dt_struct.year,
&dt_struct.dow,
&dt_struct.hr,
&dt_struct.min,
&dt_struct.sec);
I then print the values back out in a string using sprintf.
Code:
sprintf(t_string, "STD %d %d %d %d %d %d %d
", dt_struct.date,
dt_struct.mth,
dt_struct.year,
dt_struct.dow,
dt_struct.hr,
dt_struct.min,
dt_struct.sec);
But this is what I get:
STD 0 0 2 0 0 0 2
Instead of what I want:
STD 2 2 2 2 2 2 2
I've been working on a homework assignment that randomly generates integers and populates them into an array (array1). The program is then supposed to:
1.) copy those values to a second empty array (array2)
2.) sort the values already in array1 (using an inline function)
3.) enqueue the unsorted integers from array2 into a heap vector
4.) a third empty array (array3) is supposed to be populated with those unsorted integers (by dequeuing them from the heap), sorted in reverse order.
But no matter what I do, I always get garbage values like these:
I've tried using both a standard random number generator:
array1[i] = rand()%100+1;
And the d_random.h file my instructor gave us, but nothing works.
Here's the code from all 3 files:
HeapTester.cpp
Code:
#include <iostream> // Provides cin, cout
#include <cstdlib> // Provides EXIT_SUCCESS, rand, srand
#include "d_random.h"//Provides random number generator
#include "Heap.h"
using namespace std; // Use C++ Standard namespace
//Elements in each array.
const int arrayLength = 15;//100;
[Code] ....
Why I'm getting those garbage values?
I was wondering if this was even possible and if so, how do I do it.
else if (speech.ToLower().Contains("truck") && speech.EndsWith(number))
{
Here I would like to see if my speech had ended with any of the values i would have stored in the string "numbers". If it did, I would like to just take the value and add it to a new string called whatever
}
I have tried this a million different ways and I cant get it to work. I'm not even sure how I would go about storing tons of different numbers in one string, or if that's even possible.
From HP / Microsoft (Visual Studio C++) <list>:
Code:
struct _Node
{ // list node
_Genptr _Next; // successor node, or first element if head
_Genptr _Prev; // predecessor node, or last element if head
_Ty _Myval; // the stored value, unused if head
};
The stored value is wasted space for the list head. Is there any advantage to implementing list using the same structure for a list head and node?
Code:
// Write a function called insertEntry() to insert a new entry into a linked list.
Have the procedure take as arguments a pointer to the list entry to be inserted (of type struct entry as defined in this chapter), and a pointer to an element in the list after which the new entry is to be inserted.
// The function dveloped in exercise 2 only inserts an element after an existing element in the list, thereby prenting you from inserting a new entry at the front of the list.
(Hint: Think about setting up a special structure to point to the beginning of the list.)
#include <stdio.h
struct entry1 {
int value;
struct entry1 *next;
};
[code]...
This is a working version of the exercise, but I don't think I'm doing what's asked. I was able to add an element to the beginning of the list using an if statement, not creating a special structure that points to the beginning of the list. How would I go about creating a special structure that points to the beginning of the list to add a new element at the beginning of the list?
Goal: Write a program that compares the values stored in the first array to the user inputted values in the second array.

I had to change my array initialization to one with a star in front of it:
char a1[]={"a","d","b","b","c","b","a","b","c","d","a","c","d","b","d","c","c","a","d","b"};
to:
char *a1[]={"a","d","b","b","c","b","a","b","c","d","a","c","d","b","d","c","c","a","d","b"};
I also changed my 2nd array to one with a star in front of it: char *a2[20];
What does this mean exactly? Putting a star in front of an array?
Also, I am now getting an "unhandled exception" when I try to get input for my 2nd array:
cin>>a2[i];
