Eg. User input : abcde
Program Output : edcba
I keep on getting weird ASCI symbol in return, I couldn't achieve what I need, and tried debugging for days,
Code: char ar[20];
int len,n=0;
printf("enter the string to be reversed :
");
[Code].....
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 << " ";
}
Code:
#include <stdio.h>
#include <string.h>
#include <conio.h>
#include <math.h>
void reverseAr(char ar[], int n);
int main() {
int choice;
char *abc= ar[];

My codes keep couldn't get the reverse array of characters.
I am attempting to write a recursive function that, given a string, recursively computes a new string where all the lowercase 'x' chars have been moved to the end of the string.
For example,
moveXs("xxre") --> "rexx"
moveXs("xxhixx") --> "hixxxx"
moveXs("xhixhix") --> "hihixxx"
Below is the code I have written thus far, but it seems to be returning only empty strings.
string moveXs(const string& str) {
string strCopy = str;
if (strCopy.length() <= 1) {
return str;
[Code] ....
Here's my program: - Program which inputs a string from user, reverses it and displays it.
#include <iostream>
using namespace std;
void string_reverse (char [], const int);
int main() {
const int arraysize = 10;
char string[arraysize];
[Code] ....
In the string_reverse function, I have declared temp character type array but on line 38, the
compiler is throwing 3 errors: -
error C2057: expected constant expression
error C2466: cannot allocate an array of constant size 0
error C2133: 'temp' : unknown size
I have declared a constant integer arraysize in line 35. Now I have no clue why is this happening because I think as I have declared it as a constant integer variable, this should not happen.
i want to write an array sorting program that works with recursive function.but i can not do it.
my algorithm
Recursive
find the min value
find the min value and save it
find the min value and save it and remove it from loop
put the rest in loop again
find the min value again
..
...
i didnt write the function because i dont know how will it work
Code:
#include<stdio.h>
#include<stdlib.h>
#define s 5
void main() {
int a[s]={25,3,2,4,1},c[s]; // c[s] for new sorting
int i,ek,j; //ek = min
[Code]....
so my question is i want to print characters,no string just an array of characters,i do this but it s not working,maybe i have to put the '' at the end?
Code:
int main() {
int i;
char ch[5];
for(i = 0; i < 5; i++) {
scanf("%c",&ch[i]);
[Code]...
I have written a function that inserts and prints a binary function correctly.
For example a tree like this [URL] ..... would print like this
Code:
node: 10
node: 7
node: 6
node: 8
node: 9
[Code] ....
Here is my print function
Code:
void prt_tree(struct node *tree) {
if (tree == NULL) {
printf("Null Tree
");
return;
[Code] .....
Could I just make some adjustments to my function to reverse it? and if so, how?
I have an array of characters. I am trying to find "houston". The only way I can think of to do this is to use a for loop and check each individual character. Is there an easier way to do this?
char string[] = "Fishing tourism miami atlanta dallas houston";
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]....
I am trying to translate the following recursive function into its iterative function:
int f(int i)
{
if(i < 2)
return i;
return f(i - 2) + f(i -1);
}
This is what I tried to do:
int f(int i)
{
int prev,next,final;
prev = 0;
next = 1;
if(i==1)
final = i;
[Code] .....

The program should store a character array in reverse order then display the reversed array. I have also included in the code that will display the actual characters into the array as it loops through. So I know the characters are being stored, but why doesn't it display the entire string when I call it?
Code:
#include<stdio.h>
int main(){
char str[50];
char rev[50];
printf("Enter Desired Text: ");
scanf ("%[^

Is it just my compiler?
I am new to C and trying to reverse a string but the function is not getting called.. the console says :
Enter a stringabhi
bash: line 1: 229 Segmentation fault (core dumped) ./program
Code:
#include<stdio.h>
#include<math.h>
#include<string.h>
char* reverseString(char input[]);
void main()
[Code] ....
Which value change after call reverse function.
#include<iostream>
using namespace std;
static void reverse (int len, char *buf) {
char tmp[24];
int i;
[Code] ....
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]);

I'm writing a program that starts at a given number n and adds all the way to 2:
n + (n-2) + (n-4) + (n-6) + .....
The following is my code, it compiles but after I enter an integer the program crashes.
Code:
#include<stdio.h>
#include<stdlib.h>
int sum_even(int n);
int sum_even(int n){
if(n==1){
[Code] ....
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 noticed that when using variadic functions, if I pass the va_arg() as parameter to a function, the parameters get passed in reverse. Is that expected?
For example, the following code outputs
Code:
1 2
2 1
Code:
#include <iostream>
#include <stdarg.h>
void foo_func(int v1, int v2)
{
std::cout << v1 << " " << v2 << std::endl;
[Code] .....
I understand that the strrchr function is supposed to search for a string from the reverse. Unfortunately, mine isn't doing that.
#include <stdio.h>
#include <conio.h>
int main() {
char userinput[100] = "null";
char searchchar;
char *s;
char try_Again;
[Code] ....
I have code for conversion of longitude and latitude and I need to reverse the function so it will work in opposite direction:
Code:
float LongitudeDeg = argv[1]; // some longitude
float LatitudeDeg = argv[2]; // some latitude
uint32_t u,v,l,n;
l=15; // l range is 2-29
[Code] .....
On start of the code we know longitude,latitude and l. And the result is u and v. And I need function when I will know the u and v, possibly l too, to calculate longitude, latitude.
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))?
