C++ :: Printing String In Reverse Order
May 14, 2014How to print a string in reverse order(for example: "today is Wednesday " to "Wednesday is today"). My professor said we should begin with a null string and build it one word at a time.

C/C++ :: Printing Doubly Linked Lists In Reverse
Apr 1, 2014I'm currently learning how to work with linked lists, specifically, doubly linked lists, and I have come across a problem with my program when I attempt to print it backwards. Here is the portion of the code :
#include <iostream>
using namespace std;
struct node {
int data; //int to store data in the list
node *next; //pointer to next value in list
node *prev; //pointer to previous value in list
[Code] ....
The purpose of this program is to create a list, print it forwards, backwards, insert an element, erase an element, and then destroy the list. I have chopped it down to just the create, print forward, and print backward functions.
The issue I have is that in the createList function I am modifying both begin and end but I can only return one or the other. This means that whichever I don't return is still NULL in the main function and therefore does not point to anything. I've tried setting the begin/current/end to not equal NULL but createList won't work if I do that.
How I could modify both? Just to be clear, the list HAS TO be created in a function, it would be very easy to just initialize it in the main...

C++ :: Comparing Char Pointers To Integer Pointers
May 21, 2013I am a little confused while comparing char pointers to integer pointers. Here is the problem:
Consider the following statement;
char *ptr = "Hello";
char cArr[] = "Hello";
When I do cout << ptr; it prints Hello, same is the case with the statement
cout << cArr;
As ptr and cArr are pointers, they should print addresses rather than contents, but if I have an interger array i.e.
int iArr[] = {1, 2, 3};
If I cout << iArr; it displays the expected result(i.e. prints address) but pointers to character array while outputting doesn't show the address but shows the contents, Why??
C++ :: How To Reverse Bit - 1 To 0 And 0 To 1
Apr 6, 2014How 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.

C++ :: Reverse A String In Place
Jan 12, 2014I 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 found the question here.[URL] ....

C++ :: Why Are Destructors Called In Reverse
May 15, 2013"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??

C++ :: Dynamic Creation Of Arrays Of Pointers To Arrays Of Pointers
Apr 15, 2013I'm trying to write a function that takes a 32bit address and a data to store at this address.
I'm wanting to take the 32 bit memory address eg 0x12345678 and split it
into 4 x 2 bytes
12, 34, 56, 78
then each of the 4 entries is at most a 256 entry array.eg
FF, FF, FF, FF
So in this example, 0x12 points to 0x34 in the second array, which points to 0x56 in the third array, which finally points to 0x78 in the last array. This last array holds the actual data.
After successfully doing 0x12345678, say I might get a read for 0x1234AABB. So, the first and second pointers already exist, but I then have to create and write to dynamically created arrays.
The arrays need to have all entries set to NULL so that i know whether to follow the pointers to overwrite a previously entered value or create new arrays and pointers.
It all looks good and simple in the pseudo code I've written up but I'm having trouble coding it. I'm currently trying to deal with the first entry case, ie all array elements are NULL, but I'm getting confused with the pointers and creation of new arrays.
void cpu::store(unsigned int mem_add,unsigned int mem_val) {
int first = (mem_address&4278190080)>>24;
int second = (mem_address&16711680)>>16;
int third = (mem_address&65280)>>8;
int fourth= (mem_address&255);

C :: How To Reverse Unidirectional Linked List
Sep 12, 2014I 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.
