C :: How To Print Out Recursive Function In Main
Feb 9, 2013
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 trying to create a recursive function that i can call on in order to take a user inputed base and exponent and give final answer this is what i have but im completely lost after this i dont even know how to continue. What i have so far
#include <iostream>
using namespace std;
int Exp(int x,int y){
if(base <= 1 || exp == 0) return 1;
if(exp == 1) return base;
int main(){
int number, exp;
[Code] .....
After i set the base situations im not sure how to get the function to make the function take the base to the exponent recursively.

I need to make a recursive function(s) which prints the hour glass pattern. This is my code so far:
void HourGlass(int n) {
if (n==1){
cout<<"*"<<endl;
cout<<"*"<<endl;
} else {
stars(n-2);
HourGlass(n-2);
[Code] ....
Problem is, it doesn't print the spaces in front of the pattern. This is what it prints:
*****
***
*
*
***
*****
and this is what it is supposed to print:
*****
***
*
*
***
*****
Do I make a separate function for the spaces? How do I go about it?

Implement a recursive function named void printBack(DoublyLinkedNode<T>* node) for the class DoublyLinkedCircularList which will print out the elements in the list from back to front. The function is initially called with the first node in the list. You may not make use of the previous(prev) links
This is my solution where I got 2 out of a possible 3 marks:
template<class T>
void DoublyLinkedCircularList<T> :: printBack(DoublyLinkedNode<T>* node) {
if(node->next == NULL) //Correct- 1 mark
return 0;
else
printBack(node->next); //Correct - 1 mark
cout << current-> element << " ";
}

if you have something like this how can you print the string in main??
Code:
/#include <stdio.h>
#include <stdlib.h>
void myf(char *p)
{
p="balls";
}
int main()
{

Ok so I am working on a game and I'm in the process of developing my Player class. Anyways, what I have is a keyboard function that is called in my main function to make a shape move.
void myKeyboardFunction(unsigned char key, int x, int y) {
switch ( key ) {
[Code].....
But when I try to call it, trying to copy my previous method,
glutKeyboardFunc(Player1.playerControls);
I get an error
error C3867: 'Player::playerControls': function call missing argument list; use '&Player::playerControls' to create a pointer to member
I get an error saying it can't convert parameters. I would just like to understand why the arguments become a problem when I make the function a member of my class, when the first method I used is so easy.

How do I change the following recursive function into a iterator function and basically what should it look like?
int f(int i) {
if(i<2)
return i;
return f(i-2)+f(i-1);
}

I had the following question in my exam and received 3 out of a possible 4 marks
Here is the question:
Assume the following recursive function:
int f(int i)
{
if(i < 2)
return i;
return f(i - 2) + f(i -1);
}
Translate this function into an iterative version:
Here is my solution:
int f(int i)
{
int prev,next,final;
prev = 0;
[Code]....

The function is supposed to return value from the file in my main, but I am getting empty value. I am trying to get better with pointer. Right now just teaching myself.
right now the only way for this code to show value is when in put the putchar(*ps) inside my readfile function. I would like to readfile to return value and print in the main function.
Code:
#include <stdio.h>
char *readfile(char filename[]);
int main(int argc, char *argv[] ) {

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 following is my code, it compiles but after I enter an integer the program crashes.
Code:
#include<stdio.h>

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
The word is palindrome (recursive)

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 ...

I am writing a program in which a Fucntion has to be wriiten to parse the Command Line . When I include Code for parsing in main fuction iteslf ,its run ok . But I want to make a fucntion of that code and call it from main ,than it show Segmentation error .
By using Debugging I found Some thing is mess with " -m" Parameter of Command line , But Cant Rectify it ..
Code:
int main (int argc, char *argv[]){
//get_parameter_value(argc,argv);
// buffer[packet_size+1]= char ("'");
while (argc > 1) {
if (argv[h][0] == '-')

I am making a program where the user enters numbers into an array and then a number,x. The array is sorted, then x is inserted into the appropriate place. I wrote my selection sort
Code:
void Sort(int ary[], int size)
{
int temp;
int smallest;
int current;
int move;
}
[code]....
put it wont print the numbers sorted when I use my print function, just the unsorted numbers.

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...
loop r1(1,3)

this function has to check if an array is not descending it has to be recursive and it's space complexity has to be O(log(n))
Code:
int is_sorted(int a[ ], int n) {
int check=n-1;
if(n==1 || n==0) return 1;
if(a[check]<a[check-1])return 0;
else return(is_sorted(a,n-1));
}
this is what i came up with. i know it's space complexity is O(n) how do i make it O(log(n))?

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.
Code:
for (Row = 0; Row < BOARDSIZE; Row++) {
if ((game[Row][0] == 'X' && game[Row][1] == 'X' && game[Row][2] == 'X') ||
(game[0][Row] == 'X' && game[1][Row] == 'X' && game[2][Row] == 'X') ||
(game[0][0] == 'X' && game[1][1] == 'X' && game[2][2] == 'X') ||
(game[0][2] == 'X' && game[1][1] == 'X' && game[2][0] == 'X'))
return 1;
I think I need two foor-loops in each other too and need to check the spots in the board like 0,0, 0+1,1, 0+2,2. Is that even possible?

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.

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:
