How can I reverse/toggle bit like 1 to 0 and conversely, 0 to 1?
For instance: 01000100 ('D' 68) to 10111011 ('╗' 187).
Is there any way easier and more simple than:
1. Convert char/string to binary.
2. Toggle bits.
3. Convert binary back to char/string.
If I am executing following code after reversing it is giving "1" but I need "0001".
#include <stdio.h>
int main() {
int n=1000, reverse = 0;
while (n != 0) {
reverse = reverse * 10;

I would like to add a new function to my class, "reverse" that would reverse the order of the list. I have added a prototype in the "public:" section of the code (see the comment with PROTOTYPE in it). Your task is to complete the implementation (see the comment with IMPLEMENTATION in it. See the main() function to see how the results should look
#include
#include
using namespace std;
class List {
public:
// Constructs an empty list
List();

I cant seem to get the right function to put into reverse I have tried everything Im not sure where to start!
I have written a code to find reverse of a number and print if if the original and reversed numbers are equal or not .the problem is in the if condition where the first printf is not working at all. the code is
#include <stdio.h>
#include <conio.h>
int main (void)
{
[Code]....
as if i enter 121 it still shows the 2nd printf instead of 1st one. sort out the bug;;!
I was browsing the web looking for simple yet fun programming challenges and crossed this one. I figured out how to reverse the string in place but I want it to read "blue is house the". I approached it in two ways for the heck of it. My idea was the second one, the first one I googled. I didn't know a simple rbegin() could do that, pretty neat.
I found the question here.[URL] ....
Code:
#include <iostream>
#include <string>
int main(int argc, const char * argv[])

"Destructors for a derived class object are called in the reverse order of the constructors for the object. This is a general rule that always applies. Constructors are invoked starting with the base class constructor and then the derived class constructor, whereas the destructor for the derived class is called first when an object is destroyed, followed by the base class destructor."
But why, or is it just because, so programmers know which one and modify their destructor accordingly??
I am trying to write a program that reverses the elements of an array by using an function 'myreverse'. The function should reverse original array and return nothing.

great are You

I have been trying this for so long. I need to make a separate function named reverseDiagonal where I have to reverse the diagonals in a 2D array.. I have tried swapping it but i don't know where to place the "cout" and print the diagonal.

Im writing a c program that reverses the words in a sentence,
Example:
you can cage a swallow can't you?
you can't swallow a cage can you?
I have it all working, except the fact that I dont know how to get the words themselves to turn around. Heres my code and an example of the output im getting.
Output Im getting:
Enter a sentence: you can cage a swallow can't you?
Reverse of sentence: uoy t'nac wollaws a egac nac uoy?

#include <stdio.h>
#include <stdlib.h>

I was assigned to reverse a unidirectional linked list in C, where I'm not allowed to make a copy of the given linked list, or to change the actual data.
The only thing I'm allowed to do is to manipulate the list's pointers. After doing some thinking and scribbling on a piece of paper, I came up with this:
Initialize three pointers: p1,p2,p3, for the first, second and third elements, respectively.
p1->next=NULLwhile (p3 != NULL) do p2->next=p1p1=p2p2=p3p3=p3->nextp2->next=p1return p2
as the head of the reversed list
This is a pseudo code, of course, as I'm less interested in the actual implementation, and more about the algorithm itself. I was wondering if there's a more elegant way of doing this, since this gets quite complicated considering the cases where the list has less than three elements in it.
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.
Here's what I have to do: Using strcpy() pass it two strings of characters (such as a name like John Johnson) and copy the second string into the first, in reverse order, and print both. Write a main to exercise your function and to illustrate that the function is working properly.
