C :: Function To Find Starting Point For Recursive
Mar 6, 2015
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:
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.
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.
Is there any way to programatically find if the given code is taking recursive approach or iterative apporaoch using concept of files in C programming.
I have write a program to read ppm file and write a new ppm file. However, I'm not sure how to find the darkest point in this ppm file.
Note: 1. there are 610200 RGB point, but my new file only created 176196 RGB point. 2. RGB range: 0-255. (0,0,0)= black; (255,255,255)= white 3. When reporting the location of your dark pixels, assume the upper left corner of the image is location 1, 1
Using VC++ 2010 Express. I am creating a dll to export a simple Multiply function so I can use it in Excel/VBA
These e are the steps I am following :
. Create a Win32 C++ Project and give a name. For example: CallDllFromVBA . Select the DLL option in the Wizard and click Finish . In the CPP file (here CallDllFromVBA.cpp), add the following code
#include "stdafx.h" int _stdcall Multiply(int x, int y) { return x * y;
[Code] ....
The Build output show everything is ok as follows :
CallDllFromVBA.cpp CallDllFromVBA.vcxproj -> c:documents and settingsadministrateurmes documentsvisual studio 2010ProjectsCallDllFromVBADebugCallDllFromVBA.dll ========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========
In VBA, I insert a module and add the following code:
Declare Function Multiply Lib _ "c:documents and settingsadministrateurmes documentsvisual studio 2010ProjectsCallDllFromVBADebugCallDllFromVBA.dll" _ (ByVal x As Long, ByVal y As Long) As Long Sub test() MsgBox Multiply(2, 4) End Sub
When I run the Test sub I get the error: 453 - Can't find dll entry point
I also opened the CallDllFromVBA dll with Dependency walker and I can't find the Multiply export function - In fact, the dependency walker doesn't show any function exports at all for the CallDllFromVBA dll !
Let (x,y) be the center of the circle. (x,y) will not be (0,0). I have radius of the circle. Now i want to find the angle and radius of the given point inside the circle.
The recursive function is bolded, i got feedback and was told that the static variable made the function seem a lot like a iterative function but he did not say why.
Code: #define MAX 100 #include <string.h> #include <stdio.h> int checkPalindrome(char string[MAX]); int checkRecPalindrome(char string[MAX]);
the functions checks if the word is a palindrome like"level" "madam" etc. but with input "dfdfdfdffdfd" my recursive function fails.
Code:
/* main.c - Created on: Nov 9, 2013 - Author: Kaj P. Madsen*/ #define MAX 100 #include <string.h> #include <stdio.h> int checkPalindrome(char checkString[MAX]); int checkRecPalindrome(char checkString[MAX], int strLgt, int a); }
[code]....
results from "dfdfdfdffdfd" added some print to see that its the variables a and strLgt not functioning properly
Code:
dfdfdfdffdfd. The word is not a palindrome(iterative) strLgt: 11 a: 0 a: d strLgt: dstrLgt: 10 a: 1 a: f strLgt: fstrLgt: 9 a: 2 a: d strLgt: dstrLgt: 8 a: 3 a: f strLgt: fstrLgt: 7 a: 4
I am just practicing some recursion and I am having trouble with printing out a recursive function in main. Here is what I have:
Code:
// This function adds the squares 4, 5 = 4*4 + 5*5 recursiveley int recursive_sumSquares(int m, int n) { if (m < n) { return m*m + recursive_SumSquares(m+1, n); } else { return m*m;
[Code]...
I am getting an error that says undefined reference to 'recursive_SumSquares'
I am working on a problem that requires a nest for loop to be converted to a recursive function. I am going to provide just the code instead of the entire program.
Code:
for (R1=1; R1 <+3, R1++){ //for loop printf (something); } // the recursive function void loopR1 (int R1, int max){ if (R1 <= max){ printf (something);
[Code]...
when calling the recursive function in main i am using the following statement...
I am trying to learn so much C as possible by my own. I have learned a bit already and made my first game. I made a tictactoe with a 3x3 board that works great. But now i want to make it a NxN-board. But the problem right now is my checkwinner-function. I really don't know how I should check the diagonal for winner in the for loop. Earlier I have checked the diagonal manually like you can see down there.
how to write a non-recursive JSON parser function using libjson in C++. libjson is quite useful librray. It's source code of libjson comes with an example C++ parser but it uses recursion to parse JSON arrays and child nodes. I am looking for parser function based on libjson that does not use recursion to parse JSON arrays and child nodes.
Task: To create a recursive function to sort elements in an array of integers.
The function must start the sorting from the first element, and the recursion calls must go on until the last element in the array is sorted. In each step of recursion, the function must work only with the subset of array elements that have not been sorted yet.
Problem: I am getting a 'Segmentation fault: 11' in the recursive call to the function (please, see the code below).
Environment: Mac, OS X = Mavericks
Code: //////////////////////////////////////////////////////////////////////////////// ////////// Recursively sorting an array of ints. ////////// Arguments: array, array size, index from where to start sorting. void sort_incr_array_int_recursive(int a[], int size, int i){ int tmp, idx_small, small = a[i];
// Locating the smaller element in the array section.
