I have a adjacency matrix. (router adjacency matrix in network). The result should be the router ID.I mean, print all the possible paths from source router to target router(ROUTER id>> 1 - 2 - 3 - 4 so there are four one router). I get the error in the output.)
Code:
#include<stdio.h>
#include<conio.h>
/* graph: Pointer to the starting of mXn matrix
i, j: Current position of the robot (For the first call use 0,0)
m, n: Dimentions of given the matrix
pi: Next index to be filed in path array
is there any way to have the program control go some two paths at once? For example: if my program has two functions, one that does some simple calculation that requires nothing from outside it to set the variables and another that displays text for the user to read then enter something. Is there any way to have both run at the same time?
simpleFnc() {int a = 1; int b = 2 ; int c = a+b ;
[code]....
There is no connection of simplefnc to anywhere else in the program so is there any way to get it to run at the same time the other function is running?
I get a error "Not all code paths return a value" what is the reason i get this error
public String giveHint() { int hintPossible, x, y, val; _game.hint(out hintPossible, out x, out y, out val); if (hintPossible == 1) return "x: " + x + "y: " + y + "val: " + val; }
giveHint() has a red underline and it says not all code path returns a value ....
I'm trying to find vertical paths of length n through a 2D grid of numbers. Paths may connect orthogonally or diagonally. An example grid and an example possible path looks like this:
A example possible path of length n = 3 is running from (3,2) to (3,4) - All 1s ...An example of n = 4 is the run of 3s (1,1) (0,2) (0,3), (0,4)
What is an efficient algorithm for solving this kind of problem? I would like to solve (ideally) millions of grids, giving a list for each grid of all possible paths of length for n = 3-6.
I have written the below but I get an error when I run it. I get the below error.

I am trying to read data from more than one file at once. The files are different types e.g. one is a text file one is an xml file like so, StudentInformation.txt, CollegeInformation.xml. The files are all stored in one place, in this case on the D drive of a local computer. I am trying to locate any files in the D drive with a file extension of .txt or of .xml (there may be more than two of these files in the future, so I'm trying to allow for that). Then I want to open all of these files, extract the information and output all the information in one display window. I want all the information from these two or more files to be displayed together in the display window.
Here is the code so far. It is throwing up errors.
I am trying to include library paths in VS 2012 through the new property pages.I downloaded and installed mpich2-64 bit libraries under "C:Program FilesMPICH2include" and set the include path in Microsoft.cpp.x64.user property file so the path now looks like
I just want to know the code of the program: Write code to accept matrix as aurgument and display its multiplication matrix which return its multiplication matrix.
but if the matrix is compressed_matrix type, there's something with it. the error log as below:

I am trying to see if I can create an array of nodes. I think I have it down somewhat but this is what I have.
Code:
#include <iostream> using namespace std; /*This is a template of a person....sorta*/ class person{ public: int data[32]; bool selected = false; person(){
[Code]...
I am trying to see if there is a way for me to create a 86 slot array of person nodes. I am not sure how to do it and how to access them afterwards. I know that I am creating the bitstring of person correctly but I am not sure how to get the array of person going.
I'm implementing a quad tree for an assignment, and I'm not sure if every node should contain a list of pointers to every Point in its sub tree (implying the root node will contain all Points), or if only leaf nodes should contain the Points.
I wrote function to add to elements in the list, but when I call printList function it returns me empty list ! I'm new with linked list in C
Output:
Empty list List is empty add element at the begining New node with packet num 245 List is not empty add element at the end New node with packet num 486
Linked list: Empty
Main:
Code:
int main(){ struct node * start ; start = NULL; int i; /*Check if list is empty*/ if(start == NULL){ printf("Empty list
Ok so I am having difficulty adding nodes to my linked list....
how to add a third node while keeping track of the address...Thats where I get lost..I don't know how to keep track of the addresses of the next node..
#include <iostream> using namespace std; typedef struct Node{
I am trying to count every node of a binary tree internally (not passing in the root), all my attemps have ended in memory access violation or an inaccurate count (4 or 5) when it should be 10.
This is what I have tried
And yes I am NOT suppose to pass in the root.
int CountChildren() { if ( !Left() && !Right()) return 1; if ( Left() ) return Left()->CountChildren() +1; if ( Right() ) return Right()->CountChildren() +1; }
I'm trying to count the number of node in a binary tree. I have a public count function that calls a private count function. I keep getting a linker error: Undefined symbols for architecture x86_64:
"BST<int>::nodesCount(BST_Node<int>*, int&)", referenced from: BST<int>::nodesCount() in main.o
This is in Xcode. It doesn't seem to like calling the private function in the public one, but I'm not sure why since I'm doing that with several other functions.
//public function template <typename T> int BST<T>::nodesCount() {
I'm simply trying to locate possible logic errors because if I could fill this list properly, I can finish my project very easily. This is just a small portion of a very immersive project.
I am trying to create a linked list that holds objects of type Location *. I have Location defined as
I wish to clarify but can not find where to edit the OP. I believe the list is still empty because I attempt to do a simple read through the list by accessing the head and then reassigning the list to the tail of the list. However, the program never enters the while loop
Right now I'm working on a TreeView for which I would like to add a TextBlock and a ComboBox as child nodes of a Parent TextBlock node. This would look something like this:
My TreeView is implemented using an MVVM style, and utilizes a HierarchicalDataTemplate. I have had no problems with adding TextBlock nodes and TextBlock children, but the confusion seems to arise when adding child nodes of different UI types.
But then I end up with each node looking like this. It's like each node comes with one TextBlock and a ComboBox (Note: The comboBox is not the child, it and the TextBlock are one node):
How do I allow my treeView to have child nodes of different UI types? I am thinking that my solution has to do with my Hierarchical Data Template.
I am having trouble to read all attributes in all nodes called "item". I can load all attributes in one node "item" but I can't move to another node called "item " and load another attributes . I was trying a lot of different codes but I did not succsed.
This code just print all of the attributes in node called "item" but i need to move to another one and I really don't know how. I was trying to put into one for cycle another one but it did not work.
