C/C++ :: Swapping Of Position Of Elements In A Sequence

Oct 24, 2013

Write a program that gets a sequence of unsigned integers.the user can enter at most 100 integers.

After getting the numbers, the program allows the user to repeatedly choose one of the three options:

1. swap the location of two entries in the sequence. if this option is chosen the user is prompted to enter the two locations to be swapped.

2. print out the sequence.

3. repeatedly swap two locations in the sequence until getting back to the state before this operation started. then print out the number of swaps performed.

C++ :: Swapping Elements In Array?

Nov 25, 2014

I thought I'm done doing mg activity, but my professor said that we need to use a Temporary Variable for Swapping but where to put it.

Here is his activity:

Activity: Swapping Create a program that accepts a 10-element array of type int. Where the 1st user-input is stored in the 1st element of the array; the 2nd user-input is stored in the 2nd element of the array; so on so forth until the last user-input stored in the last element of the array. Your source code should be able to SWAP the values of the 1st and 10th; 2nd and 9th; 3rd and 8th; 4th and 7th; and 5th and 6th elements. It should display the values of the original and the swapped values of the array. example:

Enter 10 integer values:
array[0] = 1
array[1] = 2
array[2] = 3
array[3] = 4

C/C++ :: Swapping Elements In A Struct Dynamic Array

Dec 1, 2014

Let's say there is a document which stores data of exams of 3 subject. The document is in the below format:

Subject code [spc] Student code [spc] Exam score [endl]

Repeatedly, there are 100 data. E.g.

ENGL_S12 [spc] 000001 [spc] 90.5
ENGL_S12 [spc] 000005 [spc] 77.3
MATH_G22 [spc] 000502 [spc] 100
LATI_F11 [spc] 002005 [spc] 65.4
...

Now I have to write a function show_exam_descending(Data d, string subCode)
when I call show_exam_descending(d, "ENGL_S12")
the program will execute to show all the students' exam scores in ENGL_S12 in DESCENDING order...

For this to run, I have declared a struct Data:

struct Data {
string subjectCode;
int studentCode;
double examScore;
);

For the search, I have written a function before to load all the data from the document by using pointer and dynamic arrays. It works so well. What troubles me is the way to swap the elements (i.e. examScore) of different students in struct dynamic arrays. I am able to display all of them, but don't know how to swap.

C++ :: Indicating A Sequence Of Elements

May 20, 2013

Why is it that in the STL it is standard to indicate a sequence of elements in a container by a begin iterator that points to the first element and an end iterator that points to one past the last element?

C++ :: Building Special Order Of Elements For Given Sequence

Jun 1, 2013

Let assume that there is an array of integer numbers in the range from 1 to N that are located in the ascending order. For example

#include <iostream>
#include <numeric>
#include <iterator>
int main() {
const size_t N = 20;

[Code] .....

How can it be converted using some one standard algorithm such a way that the resulted sequence would look like

1 3 5 7 9 11 13 15 17 19 20 18 16 14 12 10 8 6 4 2

Visual C++ :: Reading Character Symbols On Lines Of Text Position By Position?

Mar 4, 2013

What I have to do is write a small program in C++ to parse the symbols that are used on 5 different lines of text in each position until position 30 is reached on each line. The goal of the parsing program is to interpret the symbols (characters), if there are any per each position, on the 5 lines of text in order to output the actual data that the group of symbols represents.

My question for is this: Is there anything special from a C++ environment that should go in to something like this outside of using standard stuff like the math associated with the search algorithm that has to happen here? The symbols are located in a file, so I know I have to include "iostream" and a few other headers. But outside of header inclusions and the code necessary to iterate and streamline the search and interpretation process, am I missing anything special that I couldn't otherwise find through simple google searches?

C :: Swapping Like Function

Feb 15, 2015

I have a question about one function in my program. Write a function that will replace players in a tim. New player gets in the game, and takes the place of one that leaves. Prototype of function is:

Code:

void replace(TEAM *p,PLAYER newplayer,int num)

where second parameter is new player, and the third is a jersey number of player who leaves the game.Two structures are defined as:

Code:

typedef struct{ char name[25],surname[25];int number;}PLAYER;typedef struct{ char nameofteam[25];int numberofplayers;PLAYER *players;}TEAM;

First I tried to read which player should get out, but that didnt work:

Code:

printf("which player should get out?
"); do { scanf("%s",p->players.number) } while(p->players.number);//

Choose one of previously read players Second thing is to read a new player and replace him with the chosen who leaves.

C :: Swapping Some Numbers In String

Jun 15, 2013

I have a pointer to a pointer to a C string:

char**objectData;

In this string there are some numbers with a dash between them, for example, "5-10". I need to read these numbers in and then increment them. So "5-10" becomes "6-11", "6-11" becomes "7-12", etc.

So far I have:

Code: char temp[350]; //350 chars is plenty enough

// Copy the first characters BEFORE the numbers into a new char array. The next characters are the numbers.
strncpy(temp, *objectData, 39); The next steps are:
- Extract the two numbers from the C string (determining if the number is 0,2 or 3 digits long) and write them into two ints. I'm stuck here.

- Increment the ints

- Write the ints into the array with a dash inbetween.

C# :: Swapping Multi Usercontrol In 1 Winform?

Jul 29, 2014

So basically, I started out with each wizard == 1 winform, but then I found another way to do it by making the content of each wizard step a user control, then say, on initial deployment, it load usercontrol1, then when i click next, the panel hide usercontrol1 for usercontrol2 and so forth. Would it be feasible to create all usercontrols (all the wizard step) and add them in an array, then i can load them by index?

C++ :: Swapping Two Adjacent Linked Lists Nodes

Oct 22, 2014

I am working on a program where I sort elements into alphabetical order and then when one is less than the other I swap them. I first did it by swapping the data but they want me to swap the nodes instead and I am having trouble doing that.

Node *add_node( Node *list, const string &s ) {
struct Node *n = new struct Node;
n->word = s; // copy string s to word
n->next = 0;

// add node n to the list
// the list should always be in ascending alphabetical order
n->next = list;
list = n;

C++ :: Swapping Nodes In Doubly Linked List?

Nov 15, 2014

I've been working on this linked list priority queue . I know that the root of the problem is in my swapUp() function (swapping the positioning of two nodes based on their priority), because the list works great up until it is called. The seg fault is not actually being caused by swapUp(), it's being caused by peekAt(), which returns the element in the node at position n. But the error does not occur unless swapUp() is called first, so that is where the issue is (I think).

There is also a seg fault being caused in the destructor, which I believe may have the same root cause in swapUp().

PRIORITY QUEUE:

#ifndef JMF_PriorityQueue
#define JMF_PriorityQueue
#include <iostream>
#include <string>
template <typename T>
class PriorityQueue{

[Code] .....

Okay, so I've tried implementing SwapUp() in a different new way, but it's still giving me the same problem

template <typename T>
void PriorityQueue<T>::swapUp(Node * target){
Node * partner = target->next; //Partner = target next

[Code] .....

This is such an elementary logic problem I don't know why I'm having so much trouble with it.

C++ :: User Defined Function - String Related Program (swapping)

Jan 4, 2015

Write a program using user-defined function which is passed a string and that function should cycle the string.(Do not use any string related functions). E.g.

If the string is : Chetna then it should print as Chetna, hetnaC, etnaCh, tnaChe,naChet, aChetn

Ans.

C++ :: Finding Nth Number Of A Sequence?

Sep 16, 2013

I have to write a program to find the nth number of the Ulam numbers.

It's a bit complicated to explain what an Ulam number is but Wolfram explains it very well here: [URL]

I have to find the nth Ulam number but I don't know what I have to do to get that. My program gives me all the Ulam numbers from a range of 0 to n.

What I want the program to do is tell me that the 49th Ulam number is 243.

/*

C++ :: Number Of Sequence In Array?

Apr 24, 2013

I am trying to write a program that checks whether the number is in sequence(as in if the numbers are in order it is a sequence). Ex: If the numbers are {1,2,3,6,7,8,9,10,11,13,15,17,20,21}, then, the underlined parts are a sequence. Now i want to find

1) the no of sequence in the array(in the above it is 3 )
2) the longest sequence (7to 11 which is 5).

C++ :: Sequence Of Fibonacci Number

Feb 16, 2014

The next code is right. I mean it works. It gives the sequence of fibonaci numbers ...

Code:
#include <iostream>
#include <iomanip>
using namespace std;
int fibo(int pos) {

if(!pos)return 0;
if(pos==1)return 1;

[Code] .....

But.... when I change the lines:

Code:
int r1=fibo(pos1);
int r2=fibo(pos2);
int r=r1+r2;

For the lines:

Code:
int r=fibo(pos1)+fibo(pos2);

It doesn't work right. Apparently it should work the same.

C :: Warning - Unknown Escape Sequence

Feb 2, 2013

I'm doing some file input/output work here in C and received this warning during compilation (GCC). My research indicates that this error is in response to white space or a character cancellation function or something like that. I'm not 100% sure exactly what it means. My code works fine, but the following warning does appear.

Code:
warning: unknown escape sequence: '40'

Here's my code (excluding a bunch of comments at the bottom of the file).

Code:
#include <stdio.h>
int main(void){
FILE *file;
file = fopen("Running Practice.c", "a");
fprintf(file, "Testing...
");
fclose(file);
}

I believe the error I received has to do with either the ' ' I used when appending text to my file, or something to do with there being a space in the file name itself.
