C++ :: Pointer Arrays - Program To Simulate Squares Most Landed On
Jun 8, 2014
I have not been using pointers that long i most of my stuff has not needed them but now they do i need to learn how to use them more. I'm writing a program that simulates the squares most landed on(for fun) and i cant get a method to work because of an array pointer.
The error is no matching function for call to 'GameLoop::Loop(int, int (*)[4])'
Here is the latest version of the code. I've been editing a lot of things so there might be some stupid errors but I've tring everything.
rolling.h and rolling.cpp are just some dice function they are working perfect.
main.cpp
#include <iostream>
#include "Rolling.h"
#include "GameLoop.h"
Rolling Roll;
GameLoop Game;

Write a program that simulates coin tossing. For each toss of the coin, the program should print Heads or Tails. Let the program toss the coin 100 times and count the number of times each side of the coin appears. Print the results. The program should call a separate function flip that takes no arguments and returns 0 for tails and 1 for heads. [Note: If the program realistically simulates the coin tossing, then each side of the coin should appear approximately half the time.]

Create a line class using a linked list that acts as a queue (first in, first out) both enqueue and dequeue. Complete the line class so that customers can be added or removed from the line. Implement the line as a linked list of customer objects that you have developed yourself or use the vector class.

Write a program to simulate a deck of 52 playing cards.
Represent your deck as a 2D Array where the value in the cell is the position of the card in the deck. Represent the names for the suits and faces as an array of Strings.
Write an algorithm to shuffle the deck.
Display the deck. For Example:
1 Jack of Spades
2 Deuce of Diamonds
3 Three of Diamonds
4 King of Spades
5 Eight of Clubs
6 King of Diamonds
7 Six of Clubs
8 Six of Spades
9 Eight of Hearts
Deal two hands of five cards each. For Example:
****** HAND 1 ******
Jack of Spades
Three of Diamonds
Eight of Clubs
Six of Clubs
Eight of Hearts
...
Below is what I have so far. Dealing two hands and displaying it. How would I be able to do that?
#include <iostream>
#include <ctime>
#include <string>
using namespace std;
void shuffle(int[][2]);
int main()
{
int j,deck[52][2];
[Code]...

The problem: I am trying to connect the 1d arrays to the 2d arrays. Right now when I write: cout << deck[3][5] << endl; The output answer is 45. How do I populate the 2d array with the 1d arrays so that when I cout deck[3][5] I get it to say "Six of Spades"?

Consider a program that simulates a card game, with multiple player hands and a deck to draw from. Each hand can use an array to represent the cards it contains; sometimes it is useful to also declare an additional variable for each hand (or deck) indicating exactly how many cards are present.
1) Describe a simple function that would manipulate both the array representing a hand and the number indicating the size of the hand.
2) Describe a simple function that might be able to manipulate the array without referring to the hand size variable at all.
3) Generally, if the array was passed as a parameter to a function, how often would the hand size be included as a parameter?

I have an assignment where i am required to code up in C, a program to simulate a taxi rank that is implemented as a queue via an array that can hold up to a maximum of six taxis.When a taxi arrives, it joins the rear of the queue. When a taxi departs, the first taxi in the rank is used and its departure is logged.A "rolling menu" comprising integer codes as specified below is used until 0 is entered to exit the simulation. I've done this stage but now the next stage is asking me to implement the queue as a linked list. what the difference is between an array and a linked list and what is a linked list?

Can I make these squares appear around the other instead of having them appear under the others. Also if it can be done how can I make it so there is a space between the squares
int main() {
char a;
int size = 0;
cout << "Enter a character: " << endl;
cin >> a;
while (size < 1 || size > 10)

I have been asked to develop a program with 6 methods which I have presented below. The aim of the program is to find and generate a magic square with a given dimension. This is a console program and so the 'Main' is also provided. However, I am having a problem with my code. When ever I try to generate a magic square it continuously cycles through 'forever' and I have never yet got a magic square; no matter what dimension I enter.
I must use methods 'CreateRandomlyAssignedArray' and 'CheckSquareMatrix'. There is another method 'SearchForValue', which we were told to creat. How this can be useful.
I have provided my code below:
class Program {
static Random rand = new Random();
static void Main(string[] args) {
int[,] array = new int[5,5];
array = GenerateMagicSquare(5);
[Code] ....

How would i calculate a surface that up to 10^5 squares cover. The info you get is xpos,ypos and width for each square.
How would you calculate the total surface covered (if any overlap only one counts).
Cannot use a big array of bools as the memory limit is 512 MiB.

I have to write a program for school that displays a random sequence of colored squares, each square is a different color. Then the squares disappear and the 5 more pop up at the bottom. The user has to guess which color was first, second, and so on. They click on the squares on the bottom that matches the first square on the top.
My question is how do you get the computer to say ok this square (that the user clicked on) matches this square here.
is there a command that says something like if this color matches this color?

I am confused whether 'malloc'ing an array of pointers and pointer to a group of arrays are the same.
Suppose I need an integer pointer to a group of arrays of 2 elements each.
int (*LR)[2];
So to dynamically allocate this pointer for M number of arrays suppose, then what is the correct syntax?
int M;
scanf("%d",&M);
int (*LR)[2];
LR = (int*)malloc(2*sizeof(int));
Whether this is correct??

The below example is an initialization of a pointer array:
char *month_name(int n) {
static char *name[] = {
"Illegal month",
"January", "February", "March",
"April", "May", "June",
"July", "August", "September",
"October", "November", "December"
};
return (n < 1 || n > 12) ? name[0] : name[n];
}
Here we have an array of character pointers. The pointers are stored in name[i]. And they point to the characters of the i-th string, which are stored somewhere else in memory. But Is the character pointer pointing to the first character in the character string that is stored somewhere else in memory? I assume so because a string itself is an array of characters. And if that is the case, how does the pointer know what the last character should be? Does it just search for the null terminator?

Do I really need to create a separate pointer to point to dynamic arrays?
T* temp = new T[capacity_ * 2];
T* tIter = &temp; //Do these need to be here?
T* dIter = &data; //Or can I use *(temp + i) and *(data + i)?
(for unsigned int i = 0; i < size_; i++) {
*(tIter + i) = *(dIter + i);
}

If i have a pointer array of classes, e.g. MyClass *foo; and if i try to delete this pointer delete [] foo; does it call a destructor of a class, or wahat happens? this is because i have another pointers in that class which are cleared in destructor.

have udp server-client application written in C. On the client side packet loss is detected using recvfrom function and sequence numbers of packets. How can I now simulate dropped packet's on the client side, for example if server is sending 1000 packet I want to drop 20% of them? I want to do this in the code, not for example using ip tables or WANEM or something like that. And one more thing, I have few clients and I want that they can dropped different packets, not the same one.
Code:
while(1){
nbytes = recvfrom(socket, buffer, MAX_SIZE, 0, (struct sockaddr *) &srv_addr, &addrlen);
if (nbytes != -1) {
// packet is received
}else{
//packet is not received
}
}

I am writing a piece of code that simulates a random walk in 2 dimensions (an object chooses whether to move up, down, left or right randomly). I would like the program to run the simulation for many objects at the same time. The way i have written it means that for every object i add the code becomes about 40 lines longer. Any method that would simplify the code so that i could have many objects but not pages and pages of code.
#include <ctime>
#include <cstdlib>
#include<iostream>
#include<cmath>
#include<iomanip>
#include<fstream>

I want to write a c++ code that due the structure of file space allocation,Simulates file system with 2*n array. Each column represents a sector. The first row is for storing files And second row holds the address of the next sector (Number of columns). And With each click on keyboard Create a file with random size and automatically find Appropriate sectors by using disk allocation method (or index allocation)... Also File names should be asked from user... And we should have file table Where the starting address of each sector,file extension and file size is given..

So this code compiles without any problem but it is not producing the correct output. I know there's a problem in either my getBlock or putBlock functions but I can't see it.
Currently the output is "Should be 32 1s: "
"Should be 32 2s: "
There should be 32 1s and 32 2s and nothing is coming out.

I am trying to simulate memory in C. I want to create a structure in C that will hold a 8bit opcode and a 32bit memory address. This would simulate a 40 bit instruction for my simulator.
I read in an old book that packed structs could be used for this to not waste space. What are the draw backs for using this? I am not worried about wasting space, but just looking for a simple way to access the memory instructions. Below is a sample of the structure that I want to use.
struct memory_area {
unsigned int opcode:8;
unsigned int address:32;
};

#include<stdio.h>
#include<stdlib.h>
main() {
int i;
int d1, d2;
int a[13];

I am trying to make a random number generator to simulate a critical hit if the number generated is from 0-critical amount. However, every time i run the code, despite being within the parameters set by the if statements, it always runs through as a critical hit and never a regular hit.
#include <iostream>
#include <iomanip>
#include <ctime>
#include <cstdlib>
using namespace std;
int main(){
srand((unsigned)time(0));
[Code]...
There are four attempts to save time in getting a good result.
