C Sharp :: How To Remove First Element From Int Array
Nov 14, 2012
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");
How can I remove an element in a list when I have only an iterator that points to the object I want to remove. Is there a build in command? remove() takes an object reference as its argument. Is it possible to convert the iterator into a pointer type so it can be deferenced and passed to remove?
This is the code I am working on:
//player.cpp void Player::CheckCollectableCollisions(std::list<Collectable>& c) { std::list<Collectable>::iterator i = c.begin(); while(i != c.end()) { if (Collider::CheckCollision(pNodes_.front().getLocation(), i->getLocation()))
This code is from a example in Jumping Into C++ and I understand the example. But it is a practice problem that is to write a program to remove an element from a linked list; the remove function should take just the element to be removed.
Code: #include <iostream> using namespace std; struct EnemySpaceShip { int x_coordinate; int y_coordinate;
[Code]...
If I got this right I will create a pointer that points to the first SHIP (getNewEnemy) and the other one will not be printed out.
This is my current code. The code is to remove the element in the list "head" that is "e". The code works if there is only one element in the list but if there are more than 1 element in the list, it doesn't work. The function should return true if there is an element that equals "e" and then it removes it and false if no element equals "e".
bool StringLinkedList::remove(const std::string& e){ StringNode* current = head; int i = 0; if (current == NULL) return false;
I am getting an error with my while loop(feels dumb) when running this code that I am allowed to modify. It is to remove all instances of an element within the list.
I want to sequentially remove one element at a time starting with the first. When the second element is removed, the first element needs to go back in. The sequence would look like
Code: // original vector, row_numbers.size()=9 row_numbers{1,2,3,4,5,6,7,8,9}; // trimmed vector, row_numbers_trim.size()=8
[Code] .......
I have been working under the assumption that the best method would be to have row_numbers remain untouched and work on a copy. For each step in the sequence, you would create row_numbers_trim as a copy of row_numbers, and then remove an element from row_numbers_trim.
Code: // position being removed int counter = 0; // copy original vector row_numbers_trim = row_numbers; // remove the first element from the copy row_numbers_trim(row_numbers_trim.begin()+counter);
All you would have to do here is to increment counter in a loop. is there a better way?
I am writing a parse system, and I want to go in and check a string for multiple Ks to be exact a K at the beginning and one at the end, if it does have a K at the end of the string I want to remove that K. I don't have an exact size of my string. I know how to remove the last K but not how to check the string for the multiple Ks.
This is what I have:
if (poNumber.Contains("K...K")) poNumber.Remove(poNumber.Length - 1,1);
I know that the first part will not work the way I want it to.
I need to remove all namespaces from xml file shown after c sharp code (also been attached). The problem is that I am getting the following error being returned by one of the functions
{System.Xml.XmlException: The prefix '' cannot be redefined from '' to 'http://sample.response.power.core.com' within the same start element tag. at System.Xml.XmlWellFormedWriter.PushNamespaceExplic it(String prefix, String ns) at System.Xml.XmlWellFormedWriter.WriteEndAttribute() at System.Xml.Linq.ElementWriter.WriteStartElement(XE lement e)
int index = -1; string NewStr = null; char[] lower = {'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'}; char[] upper = {'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'}; foreach (char c in str)
[Code]....
The code above loops through a string and for each character checks to see if it is a lower case character, then checks to see if it an upper case. It then removes it if it is. Leaving only the numbers.
However, it reuses the same string the entire time, never updating the string so it always finds the same (first) character.
I have made a new Windows Phone App and I would like there to be two versions: one without ads (79p) and one with ads (free). I have sorted out everything expect one issue. I collapse the advert if the app is in the full version but the rest of the page stays the same. How do I move the 'content panel' after the advert is collapsed?
I'm trying to find a way to remove an item that has been dynamically added when I change my drop down list selected user. The way this works is I add an edit and delete button dynamically when I select a user. I need to have the existing one be removed when I change users. Here is the code I'm using to build the two buttons. How do I remove them? Do I wipe out the columns and then add the columns again?
I am creating small application using c#.net.I removed all image tag using regular expression no I want to remove all video file and flash file also in source code of webpage.
so far I have tried this ...
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text;
So I have linked list and function which deletes element if next element is bigger, so my code is working but its not working with first element, in the comment I have wrote code which I would code for checking that first element, but when ever I check it is blowing up all program.
#include <iostream> using namespace std; struct llist { int x; llist *next;
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
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:
My code has been acting odd. I made a function that layers my art resources but only the last tile of my art resource acts the way it should. My character goes behind and in front of the last tile and gets printed correctly. Strangely its really exclusive to the last tiles I print. What I need is to figure out in step by step order what going on with my code sample below and be able to layer the resources.
Here is a small sample of my main function. This is how I do my rendering.
Code: Int main (int arc, char* args[]) { //Move class Move character; //Class Tile & Side Tile Tile *tiles [TOTAL_TILES];
how to delete an element(s) from an array; suppose I have an array x[10] = {1,2,3,4,5,6,7,8,9,10}, and I want to delete array{5} so that the values of the array become {1,2,3,4,5,7,8,9,10}; how do I go about this? This is not the same as setting the value of array{5} to null; but completely eliminating it so that it does not get printed alongside the other elements of the screen.
