Giving the following program, how do i access the swapping function. I've tried swapp::change <int> ( a, b ) ; and it gave me 4 errors. Here's the code:
#include <iostream>
using namespace std;
template <typename T>

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.

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.
#include <iostream>
using namespace std;
char swamp(char a[], int x) {
for(int k=0; k<=x; k++) {
char l= a[x]; a[x]= a[0]; char p=a[x-1]; a[x-1]=l;
for(int i=1; i<x-2; i++) {

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.
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

I have a function that is suppose to swap positions of 2 letters but It doesn't seem to work. Im passing in the array of char into the function.

I am essentially trying to get a value from a 'Matrix' that is created. Using a function in the class where the matrix is created. But when trying to do this I get the error: Call to non-static member function without an object argument in this line when trying to call the function:
Matrix::get(sizeR, sizeC);
I tried normal swapping method like this (counter is number of structures written in file) :
Code:
fopen("books.txt","r+");
system ("cls");
for(i=1;i<counter-1;i++){
for(j=1+1;j<counter;j++){
fscanf(f," %[^,], %[^,], %[^,],
[Code] ....
But it doesn't do anything.
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?

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.
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;

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{

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

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

if we don't provide the acces modifiers for base class and we need to manipulate the private data of base class in derived class. Is there anyway to acces the private data members? Here's a coding example
class A {
private :
int a;
};
class B : public class A {
public :
void displayA() { cout<<a<<endl; }
};
how i can acces the a of base class A in derived class B without acces modifiers.

x is declared outside the functions and defined inside main(). Then why this code produces a compile error?
x is already declared so it can be used in f(); and when I call f(), x is already defined. Then why can't f() sets the value of x (in main) to 10?
