May 17, 2013Suppose I have a class "A", which has a method "void AMP_call()" that calls paralel_for_each in which another method, "float amp_function(float) restrict(amp)". When I call that method, can it then use members of "A"?
class A {
void AMP_call();
float amp_function(float) restrict(amp); // do something on a device
float allowed_variable;
std::vector<bool> not_allowed;
[Code] ....
Another way to frame my question, perhaps to make it easier to understand what I am after, would be that I want to know what happens if an amp-restricted method is called where the body of the class itself (which is not amp-compatible and afaik doesn't have to be since it's not passed to the device) may contain members that are not amp-compatible.
All of the msdn blogs I could find deal with which functions and methods can be called from within a parallel_for_each loop, but not with which variables are available to the lambda function itself.
C++ :: Data Structure - Program Using Stacks
Nov 3, 2013Given a set of different types of paired symbols; determine whether it is balanced or not (the opening and closing version of each type are paired correctly). Any other type of characters may appear in the input will be neglected.
For example:
(**(*[*])****) is balanced, also [{}**[]**()]** is balanced. But ((*{*)*}) is unbalanced as well as [()***[]***{*(*)}.
Write a C++ program that requires a string containing and expression as an input from the user and check for balanced bracket pairs using stack data structure.
Here is my code which give me nothing when I run it.
#include <iostream>
#include <string>
using namespace std;

View 12 Replies View RelatedC/C++ :: Intuitive Data Structure To Use For Memory Management Program
Mar 21, 2014I have an assignment that wants me to better understand how certain calls like malloc() and free() work. I'm supposed to have one function that allocates a pool of memory for the program to use (this is the only place where I'm allowed to use the malloc function. Anyplace else is off limits, except when allocating space for data structures.) Another function needs to be defined that allocates memory from this large pool of memory that we have already allocated. A third function needs to free a block of memory when a call from function main is made and a fourth does something else (haven't gotten that far yet.) I'm not sure if it's ok or not, but I'll attach the pdf form that describes all the requirements. If that's not ok, I'll delete it.)
Anyways, when thinking of data structures to use for this particular problem, one doesn't jump out at me as being THE data structure that would be most useful. How I would imagine using it is to store the addresses currently being used as well as the block length of those addresses (so basically, each node of the linkedlist would have a pointer that points to an allocated address and another field that told the size of the allocated block of memory.) How to communicate to the large pool of memory that a certain block of memory has been allocated and shouldn't be used until a free is made on that specific block of memory.

C++ :: Asymmetric Data Structure
Mar 18, 2013I am trying to create an structure of data with following elements:
struct stest {
std::vector<int> na;
std::vector<double> nb;
std::vector<double> va;
std::vector<double> vb;
std::vector<double> vc;
std::vector<double> vd;
}
I would like to modify the composition of this struct, so that I can create a special data structure by
vector<stest*> data_test;
for(int i = 0; i < 10; i++)
data_test.push_Back(new stest);
within this structure, I have: only one na and one nb, but ten groups of combination of va, vb, vc, vd that I can access by pointer, which means na, nb are independent but still inside of the structure.
C++ :: Two Dimensional Map - Data Structure
Apr 4, 2013I'm currently having the following data structure:
typedef struct {
int a;
int b;
} S;
<vector <vector<S> > v;
Now I also have different pointers that can be set in connection with one instance of the above shown vector. Therefore I was attempting to work with a map:
map<p*, <vector<vector <S> >, vector<sI> > m;
However, it seems like it doesn't work that way. Therefore I tried the following:
map<p*, map<<vector<vector <S> >, vector<S> > > m2;
With this attempt I do now, however, get another mistake here, that [] cannot be used here:
S s;
m2[p][0].push_back(s);
C++ :: What Data Structure Does A Vector Use
Dec 14, 2013Does it use Linked List or Dynamic Array?
I want to know this because if I happen to want to use a lot of insertions and deletions then it is more efficient to make use of Linked List instead of Dynamic Array.
While, if I happen to want to just access random parts of the Array, then Dynamic would be more efficient.
I want to make a 2D game using SDL engine and I need to check whether or not an object is colliding with a list of other objects. (because there would be more then one objects on the map.)
Since I would simply be accessing each object sequentially to check whether or not the object is colliding with another the object in question, and since any of those objects could "die" and be deleted at any time, it makes more sense to use Linked List then a Dynamic Array.

C++ :: Corporate Data Sales Structure
Nov 20, 2013Corporate Data Sales
Write a program that uses a structure named CorpData to store the following information on a company division.
Division Name(North, South, East, Or West)
First quarter sales
Second quarter sales
Third quarter sales
Fourth quarter sales
Total annual sales
Average quarter sales
Include a constructor that allows the division name and four quarterly sales amounts to be specified at the time a CorpData variable is created.
The program should create four variables of this structure, each representing one of the following corporate divisions: North, South, East and West. Each variable should be passed in turn to a function that calculates and stores the total annual sales and average sales for that division.
Once this has been done for each division, each variable should be passed in turn to a function that displays the division name, total sales, and average sales.
Here is my code:
#include "stdafx.h"
#include <iostream>
#include <string>
using namespace std;
struct CorpData {

C :: Data Handling And Structure For Embedded UAV Project
Apr 16, 2014Data handling for a UAV project I am trying. My background is in Microcontrollers but I have never had exposure to "sound" programming practice...
I have got 2 microcontrollers to drive a UAV craft I've made. One "firmware" micro collects all the sensor data and then passes it to the other "application" micro for control processing. Once decisions have been made this is sent back to the "firmware" micro so that actions are taken.
So in essence I am sharing a raw data chunk periodically between the 2 processors that has outputs and feedback data. For the moment this is captured as one big buffer array on either micro after receiving. For easier structure I thought of bouncing this buffer that contains all sensor information and control variables between the 2 processors (visualize a ping pong game with all the possible variables from both micros - bandwidth between the micros is not a limitation) There are quite a few modules that want to access information from this buffer and write control actions back to it.
I was thinking of constructing a struct on both micros to access this "raw data" from the buffer and set it up with variable names so that it is easier for functions to read info and write controls back.
But this would mean that the data is accessible to every function, and there is the fear that some functions will write to the input data or write to control variables that they should not have access to. I also need to reduce memory copies and the like due to limited memory on each micro.
C :: Compact Table Representation - Data Structure
Jul 19, 2013Data structure problem. I have a table of the following format:
Code:
C/R 1 2 3 4 5 6 7 ...
1 x x x
2 x
3 x
4 x
5 x x x
6
... s
So my column and row names are integer numbers if an outcome of some game for a certain column and row lable is a match then we have an x on that position. The size of the integer names for both column and row name is quite large (let us imagine that it is so large that you would need a machine with 500GB of RAM memory to hold this type of table even if x's are treated as regular char's) . In every row there is at least one x and for every column the same holds for the columns. However, the number of x's for a row or a column can be bigger then 1. How to store this table efficiently? (using as less memory as possible).
The data structure should be efficiently accessed in the column fashion that is, if i want to get all values for column 4 I should be able to do that in O(N) time where N= the number of rows.

C/C++ :: How To Create Objects Of Same Data Structure (type)
Dec 31, 2014well i create a State.h class
#ifndef STATE.H
#define STATE_H
class State {
public:
virtual void handle_action() = 0;
virtual void update() = 0;
virtual void render() = 0;
};
#endif //STATE.H
What i'm trying to create is a simple State Manager for SFML! I created another class that inherits State.
#pragma once
#include "state.h"
class FirstState : public State {
public:
FirstState();
~FirstState();
void handle_action();
void update();
void render();
};
So the question is this, each state that i have will inherit the State class. However, i wanted to perhaps add each state object into a vector array. But i'm not sure as to what data type it be? I have a state manager class that will contain the vector.
What i want to do is this, each game state will create an object that will inherit functions from the state.h class. I want to store them all in a vector array, but each object is clearly named different. My curiosity was wondering, since all those different states inherit the State.h class, can i simply create a State Object std::vector<State> *states; that will contain all those different state objects?

View 2 Replies View RelatedVisual C++ :: Print Sequence Data Structure
Sep 15, 2012Printing out a sequence data structure. I am using a PC running Windows 7 with Microsoft Visual Studio 2008. This sequence has a dynamic array which stores a value_type which can be any of the built in data types for C++. Initially the sequence is 30 slots long. When the program starts the user starts at the beginning of the sequence by choosing the "!" option from the menu. The user will then insert a number such as 11 by selecting the "I" option (upper or lower case). Then the user will go to the next position in the sequence by selecting the "+" option then insert 22, then go to the next position and insert 33.
To show that the numbers are actually in the sequence the user goes back to the beginning of the array by selecting "!" and then select "C" to display the current number of 11. Then the user goes to the next position by selecting "+" and then "C" to display 22 and so forth. At this point the member function called current() works just find , but when trying to print the contents of the entire sequence the program displays garbage. Why?
Code:
// FILE: sequence_test.cpp
// An interactive test program for the new sequence class
#include <cctype> // Provides toupper
#include <iostream> // Provides cout and cin
#include <cstdlib> // Provides EXIT_SUCCESS
#include "sequence2.h" // With value_type defined as double
using namespace std;
using namespace CISP430_A2;

C :: Implementing Trie Data Structure With Dynamic Array
Jun 23, 2013i can't implement trie with dynamic array .the problem is in this line i think :
Code:
childs_size = (node_p -> childs_value_p)[0] + 1; here is my code : Code: #include <stdio.h>
#include <stdlib.h>
#include <string.h>
struct trie_node {
unsigned char *childs_value_p; // pointer to an array of child nodes value
struct trie_node **childs_ptp; // pointer to an array of child nodes pointer
struct trie_node *failure_node_p; // pointer to failure node
[code]...
i could write this code with binary tree instead of dynamic array but need a large amount of memory for about 13000000 strings of length 16 . is there any better solution with lower memory usage to implement trie ?
