C :: Store Character Array In Reverse Order Then Display Reversed Array
Jun 14, 2013
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?
I need fastest method to reverse order of bytes in my char array.
For example i have:
unsigned char buf[8]; // consider data stored in buf is 88 77 66 55 44 33 22 11 // how to reverse it to: 11 22 33 44 55 66 77 88 // currently i can do it by equal assignment , i make another buf like: unsigned char buf_ok[8];
[Code] ....
// This does reverse the bytes as i want but its very slow , i am looking for fast method ..
I'm trying to use a priority queue sorting in reverse order to take a vector or 2d array. The problem is that I want to sort by the vector/array cell value but keep the reference to the vector/array index of the value. I don't know quite howto keep them both related so when I pop. I can find the corresponding cell.
Using the array to accept 10 testscore. Calculate and print the highest, lowest, fifth test score entered and all the test score entered in reverse order.
How i would get it to print the highest,and lowest and in reverse order. I'm confused as to what to do...
I need to reverse a word . For instance "Hello" after reversing will be "olleh" . It reverse first and last letter but its not reversing the rest of them
char arr[]="Hello"; int first=0; int last=sizeof(arr-1); int mid=sizeof(arr)/2;
I'm coding a hangman game. I'm trying to store user entries so i can output them to show the user what they have already entered. Problem is that it's not display anything at all.
I'm trying to store multiple characters of course, and then display all characters stored.
How 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.
#include <iostream> #include <fstream> #include <string> using namespace std; int nwords(string);
I am currently having an issue with validating user input for a state abbreviation. I have an array where a list of abbreviations is stored to use as a comparison for whatever the user inputs. I have been able to get the list loaded properly but whenever i go to compare, it always comes back as true even if it isn't. Here is some relevant code:
static char stateTable[STATE_TABLE_SIZE][STATE_SIZE]; int main() { char buffer[40], *testCustName[40], testState[5], testCode; buffer[0] = ' '; int quit = 0; int p = 0;
I have two vectors of float that I need to sort in reverse order. reverse() seems to work for one of them, but not the other. I have toggled between sort() and reverse(). for one vector, the expected behavior is seen and the order reverses. For the other, there is no change in order.
This is very simple code, so it's hard to imagine what is going wrong.
You can see that the order of the first vector did not change. Am I right in suspecting that the numbers are too similar for what ever method reverse() uses to determine the difference between values?
The next step for my project is to take data from a file, and create a new file with the same data, but in reverse order. If a file has the following values:
1 2 3 4 5
The program should create a new file with the following values:
5 4 3 2 1
Seems pretty straight forward, yet I am hitting a snag when I try to compile my program:
The following errors occur when I try to compile the fore mentioned code:
intrev.c: In function 'main': intrev.c:25: warning: unused variable 'out' intrev.c: At top level: intrev.c:39: error: expected identifier or '(' before 'while'
[Code] .....
Now I am not concerned with "unused variable 'out'" as it is used, just in a for loop. Is this a problem?
I'm not entirely sure why it's giving me the error at line 39. I've gone over this a couple times and it doesn't look like I've missed any methods which need to be closed. Maybe I've missed something?
I'm also not sure why I am getting an error when I try to close the opened files. I've done this before in the same manner, but without errors. Not sure why I am now, but my guess is that it has something to do with the error on line 39.
I was trying to reverse a linklist in reverse direction using the recursion. I was able to reverse n - 1 element but it is not printing the first one. Below is my code.
Code:
typedef struct linklist { int data; linklist *next; };
void add(int data,linklist **node) {
[code]....
This is happening since recursion is starting from second node, which is due to reason not printing the first one when recursion print values from stack once
node != NULL
Condition is met.
Currently I am using below statement for printing the first element;
reverse_recur(node); printf(" Print In Reverse Order %d ",node->data);
1. Construct a class diagram that can be used to represent food items. A type of food can be classified as basic or prepared. Basic food items can be further classified as meat, fruit, veg or Grain. The services provide by the class should be the ability to enter data for new food, to change data for food and to display existing data about food.
using this class definition write a main program to include a simple menu that offers the following choices:
1. Add food 2. Modify Food 3. Delete Food 4. Exit this menu
2. Read a list of numbers from a file and then print them out in reverse order. State whether the list is palindromic or not.
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.
In my program, the function 'myreverse' is not getting invoked and the original array is being displayed as it is.
#include <iostream> using namespace std; void myreverse(int arr[],int n) { int *p=&arr[n-1]; int temp; for(int i=0;i<n;++i)
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.
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 << " "; }
