I don't know how to turn this recursive function into an iterative...
I am trying to make from f_rec (recursive function) to f_iter (iterative function) but I can't.
(My logic was to create a loop to calculate the results of f_rec(n-1), another loop for 2*f_rec(n-2) and one loop for f_rec(n-3);
But I'm wrong)
int f_rec(int n) {
if(n>=3)
return f_rec(n-1)+2*f_rec(n-2)+f_rec(n-3);
[Code] .....
I also think that my run time for the f_rec is 3^n ...
So I have a code like this one below :
void get_sum( INNER_ID id, vector<INNER_ID>& dont_check ) {
vector<INNER_ID> below = get_below( id );
vector<INNER_ID>::iterator second;
[Code]....
I use this algorithm for my "crappy" physic engine, so the point of this algorithm is to get the sum of mass below an object. get_below( id ) function can get the ids of what object is below them.
But before I need ids of the object below them to apply impulse, force, and some other physic stuff.
One object doesn't neccesarrly rest on top of one object, it can rest on 2 object or more.
when I look at it, it resemble a tree, maybe it's not. I just don't really know very much about tree algorithm
I cannot optimize a recursive code so I think, I better turn this into an iterative but I cannot seem to find a way to do that
Thing I want is find the largest sum down a triangle,(moving to adjacent numbers on the row below )there are many methods to go down.

I wrote a program with a recursive() called finder. But it dose not work properly,at run time it becomes to a infinite status. How to detect the error at runtime. Here is the code.
#include<stdio.h>
void finder(int x,int y);
int tot;
[Code] ....
I think the error is the changing value of x after a round of for loop.
In this code nothing modify except function minMaxSearchRecursive
Code:
int min(int a, int b) {
if (a < b) {
return a;
} else {
return b;

I am trying to create a function to find the entry point of my map.But my program does not seem to be working correctly. I am trying to place a dot there because I will have to use recursion to fill up the whole map. But I'm not asking for the answer. I just need writing a function to locate the starting row for the first column of the maze (first non zero element). My code seems to have a bug in it when I try and call my function FindEntry. What I am trying to do is read in column by column until I can find the starting point and then place a dot there with ASCII character 249. This is my code so far:
Code:
#include<stdio.h>
#include<Windows.h>
#define HEIGHT 21
#define WIDTH 78
[Code]....
If you try and run it, it will give you a bug. But if you comment out the FindEntry function in the main it will work and look like this:
I am supposed to write a recursive function which find the partition of a number n ,, for example if n=3 , it should print 1 1 1 , 1 2 , 3
I wrote the program but i am getting the two partition 1 2 and 2 1 which are the same ,, how can i avoid that ?
this is the code :
void PrintPartition( int n , int A[] , int j ) {
if( n<=0 ) {
printArray( A, j );
return ;
} for( int i=1 ; i<=n ; i++ ) {
A[j]=i;
PrintPartition( n-i , A ,j+1 );
} }
the first call of the function is : PrintPartition( n , A , 0 ) ;
For an assignment I have to finish prewritten code which consists of multiple source files and a header file.
Code:
#include "tree.h"
#include <fstream>
#include <iostream>
#include <string>
using namespace std;
[Code] .....
I understand that I have to find the height by using _left->height() and _right->height() as long as it is not a null-pointer , each time I do this the values of _left and _right change. That way you can check if it is possible to go further down in the tree. I also have to use a counter to keep track of the number of layers at each side of the root. I don't understand how to implement it.
int a = 9, b = 4, c = -1;
c *= --b * a;
I am trying to write code to find all the prime numbers before a user entered number. I started with a working program and when I tried to create a function, it got all messed up.
Code:
#include <stdio.h>
int is_prime( int num );
int get_positive_integer(void);
int main( ) {
int upper; /* upper limit to check */
int num; /* current number to check */
int isprime;
/* used to flag if number is prime or not */
[Code]...
It says the error is on line 23
I'm writing the function as described in the title but it isn't quite working. It works as long as the value passed is less than the parent (going left) but when the value should be placed to the right, it doesn't actually insert the node.
template <typename T>
void BST<T>::insertHelper(BST<T>::BinNodePtr &subRoot, const T& item) {
BinNode *newNode;
BinNode *parent;
BinNode *child;
[Code] ....
FYI, I've commented out setting the children of the new leaf to NULL because the constructor already does that.
I tried my best but I can't figure out the problem. At the last part of "createArray", I output the final array created. I mean it to repeat once but then it repeat more times than I expect. createArray is an iterative function. If it repeats 3 times, than at last the array created which fulfil the criterion would be printed out 3+1 times.
I am trying to create an array with 3 numbers 5 times, resulting in a 2D array. The 3 numbers in a array are picked from 0 - 5. I enter createArray(5,3,5). Then these 5 arrays are compared with each other to see if there are repetitions. If there are, the whole process begins again, 5 arrays with 3 numbers each will be picked again and compared with each other. If there are no repetitions at last, there 5 arrays would be printed out.
void deleteArray(int** array){
delete[] array;
}
int** createArray(int simu_times, int randomrun,int numberofrun){
vector<Int_t>fChosenRun;
int** Array = new int*[simu_times];
[Code] ....
im trying to write a source code that find the smallest, largest and average of numbers in array. the code runs fine, but it is not giving the highest number and the the average should include only four number excluding highest and smallest number from the array.
void OlympicJudging() // Olympic Judging {
int numbers [6];
double average, sum = 0;
int temp;
for(int i = 0; i < 6; i++){
cout << "Please type a value for scores: ";
cin >> numbers[i];

I was studying BST and tried to make a iterative function to insert, the original recursive function is the following:
void insert(node *&tree, int value) {
if (!tree) {
tree = new node;
tree->num = value;
tree->left = tree->right = NULL;
[Code] ....
And the code that i did is (but doesn't work):
void insert(node *&tree, int value) {
if (!tree) {
tree = new node;
tree->num = value;
tree->left = tree->right = NULL;
[Code] ....
I don't see where the error is or why it doesn't work.
I am trying to make a utility program for work that will update multiple projects with local dll references. Basically I work with two solutions (for talk sake solutIon1 and solutIon2). Generally solutIon1 will reference the dll's built In solutIon2 which reside on a server. However for debugging proposes I sometimes need to D/L the solutIon2 projects and build them local-ally, so that I can reference the solutIon2 dll's local-ally (this Is so that I can easily attach the dll and step Into the code). However this require changing the reference paths, so that I am pointing to the local-ally built dll's, which Is quite a laborious task.
So the question is how would I update references in solution1 from the program that I am making. I don't really know what to start reading about as I have never done anything like this before.
when we are trying to shift one tab to other one event should occur, can any one tell what is the event,how and where we have to write the event? give example. if he successfully login in first tab only then second tab will open,if he doesnt login in first and tries to open the second tab message should appear...

How can I save an CDocument programatically, without to bring him to the top, only if I get a pointer to that document ? I mean if I have several document opened into a MDI app, and if I have a pointer to one of them, to save it without to turn them as active childs ?
View 3 Replies View RelatedI'm trying to get my C program to perform a few shell commands in a Linux environment, one of them being mount. The specific command is:
Code:
mount -o rw -t ext3 /source /destination
If I put the above command in a system() call, it works. However, i tried to call mount directly, as defined in sys/mount.h, as follows:
Code:
mount("/source", "/destination", "ext3", 0, "rw");
This doesn't work - it throws me back the error "Invalid argument".
Did I translate wrongly? What's the correct syntax?

I have looked into this and I've also read that I should be able to Config Each column Accordingly.

Currently it does not error, but it also does not Show the DateTime in the GridView when running either..
