I implement copy constructor for priority queue like this, is it right?
PRIORITY_QUEUE<T>::PRIORITY_QUEUE(const PRIORITY_QUEUE &aQueue)
{
this->maxSize = aQueue.maxSize;
this->items = new T [maxSize + 1];
this->rear = aQueue.rear;
for (int i = 0; i < aQueue.rear; i++)

By the way, how to implement "insert" and "heapify" and in insert, when we insert an element we also heapify it?
I am unable to implement the insert function properly, every time i run the program i just get the first value and name, I am not getting other Id's and name.

how to insert a variable for the size of array and prompt user to insert the elements for the array?
View 13 Replies View RelatedI'm trying to learn how to implement vectorization. Lets say I have this an array like this.
Code: int Array[10] = { 3,4,5,3,4,5,6,7,8,9};
If I traverse through the array and preform some simple calculation like adding numbers, how would I go about vectorizing this feat? For example if I want to add numbers, .
An example, add element at index 5,6,7 to element with index 1.
Code:
0 1 2 3 4 5 6 7 8 9 --- index
3,4,5,2,8,2,3,5,1,2 --- ints
When inserting elements in a set it should only insert unique elements but I get duplicates too.
Code: #include <iostream> // cout
#include <algorithm> // unique, distance
#include <string>
#include <iterator> // std::back_inserter

I have a dice roller program that I want to use in different program and I know there is a better way to add than copy and paste all of the code, but dont know how. Can I attached it as a file and call the file in my main program?

I have to make a prgrama using the C programming language that is able to read several lines of commands entered by the user and interpret it as a command to run.
I have to implement the following command:
a) Command generic - program should be able to read any one command and execute the same command on the operating system through primitives for implementing generic processes (eg "ls-l/etc").
Code:
char str[40][40];
int number = 7;
for (int i=0;i<number;i++){
printf("enter %d th string::",i+1);
scanf("%s",str[i]);
}
Above, I have a little snippet of a code that I'm trying to figure out. I don't really understand how to implement 2d arrays in C that well. But, I mostly want to know is how and where the strings are being stored, especially with the code below.
Code:
for (int i=0;i<number;i++){
printf("enter %d th string::",i+1);
scanf("%s",str[i]);
}
I know that it's asking the user to enter strings, which will be stored into the 2d array. I just don't understand how it's being stored. Will it be placed in the 1st column or 2nd row or something?
I'm trying to implement the flocking algorithm in C++. I've tried to implement it myself by making all the particles 'home-in' on the player. When 2 particles then collide within their larger bounding boxes they home-in to each other. And when the 2 particles are actually touching they repel each other until they are outside of their bounding boxes and find another particle to home-into.when I run my application the particles all home into the player and come to a stand still along the Y-axis above the player.
All the particles in question are stored in a Vector, with a pos and velocity.
for(int i = 0; i < swarm.size(); i++) {
for (int j = 0; j < swarm.size(); j++) {
if (swarm.at(i)->getParticleModel()->getPosition().x < gameObjects.front()->getParticleModel()->getPosition().x) {
if (swarm.at(i)->getParticleModel()->getTouching() == false)

Ok so i am coding in WPF i was coding just fine and im trying to implement a browserDialog
Here is the class
The issue i am having is in the DialogResult.Cancel This is the issue i receive 'System.Nullable<bool>' does not contain a definition for 'Cancel' and no extension method 'Cancel' accepting a first argument of type 'System.Nullable<bool>' could be found (are you missing a using directive or an assembly reference.
private void ArmaPathSelect_Click(object sender, RoutedEventArgs e)
{
FolderBrowserDialog folderBrowserDialog = new FolderBrowserDialog();
if (folderBrowserDialog.ShowDialog() == DialogResult.Cancel)
return;
this.Path_Arma3.Text = folderBrowserDialog.SelectedPath;

I do this because I want to transform the .x format into xml... The "frame" data structure can contain other frames, and a name for the frame and a transformation. For example:
Code:
struct frame {
std::string name;
Matrix transform;
std::vector<struct frame> child;
std::vector<struct frame> sibling;
[Code] ....
I know the above won't compile. But am I on the right track to implement data structures this way using linked lists? about directx, I'd like to ask is the .x format implemented with a tree structure rather than linked lists.
Let's say i have a string "file.txt" and i want to insert "_out" to make it look like "file_out.txt"

I have lots of files needed for program named text1,text2, etc. I tried to do a loop like this:
ofstream of;
for(char i='1';i<'9';i++)
{
of.open("text"<<i<<".txt");
}
I tried without << too, but it doesn't work neither. How can I make it work, without writing a line for each operation?
My program will ask the user to enter the number of lines for the sentence "I will always use object Oriented programming. " if for example, the user enters 3, it should print out
I will always use object Oriented programming. I will always use object Oriented programming. I will always use object Oriented programming.
the second part of my program asks the user to enter the line which we want to make a typo. If they enter 2, it will replace the "I will always use object Oriented programming. " with "I will always use object Oriented programing." in the second line.
this is how it should look like but I am having trouble putting the second part together. I don't know how to remove the sentence and replace it with the second part.
Enter the number of lines for the punishment: 6
Enter the line for which we want to make a typo: 3
I will always use object oriented programming. I will always use object oriented programming. I will always use object oriented programing. I will always use object oriented programming. I will always use object oriented programming. I will always use object oriented programming.

Make a C++ Program that will use nested if else and any looping statement to display the following a certain number of times depending on how many times the user wants it to do so.
Input Values:
1. Name of employee
2. Position in the company
3. No. of hours worked
4. Rate per hour
5. Overtime hours
Required Output:
No. Name Position Rate per No. of hours Basic No. of overtime Overtime
hour worked Pay hours Pay
1. Juan Manager 160 140 22400 10 2100
Computations:
basic pay = no. hours worked x rate per hour
overtime = overtime hours x 150% of rate per hour
Just asking how can I input the name, position, rate per hour, overtime hours and hours worked in a horizontal manner?
Because I need to achieve the required output.
