I am trying to solve the following task:
-Write a recursive function that prints an integer with decimal separators. For example, 12345678 should be printed as 12,345,678.
The problem is that I don't know how to modify the integer in such way. I was thinking to convert it into a string, do an algorithm and then turn the string back to integer.
How to do such modification.
I am trying to read hex data from a file (not just hex values in text format). I was able to read it (02 EC) with "fread" into an char before but I need to change the Hex value into an integer in decimal.
I already read about strtol but I would prefer reading the hex Value into an integer.
Here is my code so far:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main() {
int itrack1[1];
int itrack2[1];

I am trying to print out 2^1000. I am not entirely sure on how to implement the constructor. I currently just have x.push_back(n) as my constructors implementation. For the function double(), it is suppose print 2^10 as 1024 and the function addDigits() should print 2^10 as 7. Am I suppose to create a Long object with 2 as a parameter and then use double() to double it 10 times?
#include <iostream>
#include <vector>
#include <iterator>
using namespace std;
class Long {

Write a C++ application program to accept a signed decimal integer as input and output the equivalent 2s complement version in 16-bit binary. Include a space between every four bits in the output string. The input will only be processed by the application if it falls in the valid range that can be represented in 2s complement format with 16 bits. The range of a decimal number from - to + is -32768 to 32767.

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);

int f(int i)
{
int prev,next,final;
prev = 0;

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.

the functions checks if the word is a palindrome like"level" "madam" etc. but with input "dfdfdfdffdfd" my recursive function fails.

#define MAX 100
#include <string.h>

int checkPalindrome(char checkString[MAX]);
int checkRecPalindrome(char checkString[MAX], int strLgt, int a);

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);

I also think that my run time for the f_rec is 3^n ...
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...
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.
View 1 Replies View RelatedTask: 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];

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:
Eg. User input : abcde
Program Output : edcba

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 ) ;

Write a recursive function called sumover that has one argument n which is an unsigned integer. the function returns double value which is the sum of reciprocals of the first n positive integers =.
for example sumover 1 returns 1.0
sumover 2 returns 1.5 like 1/1+1/2
