I wanna store my data by descending order auto without doing a classification after , i have come up with a code but it crashes.
Code:
void list::create(int num) {
struct node * n,*temp;
n=new node;
n->data=num;
if(head==NULL)
[Code]....
I don't wanna use the list library with the push.buck, i need to do it by coding it without fix functions ....
so my program reads a file type which looks like this...

Here is whats in the header of the class
class StudentStat {
private:
int Size;
[Code].....
So as of right now the names are stored in a Names string array and the scores are saved in a Score int array. So my question is where do I begin with my bubble sort? I need it to put the scores in descending order so from greatest score to lowest but I need the Names in the string array to still be connected to the number from the list. Never done a bubble sort before so not sure where to begin.
I have to put these numbers in ascending and descending order . The interesting point of the function is that sortMe does NOT re-arrange elements in the array; instead, it uses a second array, an array of indexes for the elements in the original array and then sortMe sorts the second array based on the values in the original array. A sorted version of the original array can then be produced with these sorted indexes. I'm not sure why the function is working, even though I called it in main.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
void sortMe(int array[], int sortedIndexes[], int size, char mode);
char option;
const int SIZE = 5;
[Code] .....
I'm stuck again on a homework problem. I enter 9 8 7 6 5 4 3 2 1 in to the program when it asks me to. I print out the array (just before the bubble sort routine) and I get the numbers in descending order just as expected. So going into bubble sort routine, the numbers are correct.
I should get 1 2 3 4 5 6 7 8 9 as output.
But I get 1 2 3 4 4 5 6 7 8
Code:
#include <stdio.h>
#include <stdlib.h>
int main() {
int max_size = 20; // max size of array of numbers
int numbers[max_size]; // array for numbers
[Code] .....
What kind of code should i use for sorting numbers in both ascending and descending order? I don't know how to use bubble sorting either, is there another easy way to sort this out?

This code is for (hospital management system).
This code allow you to add patients.
There are two types of patients. which is:
1. Normal patient.
2. Critically ill patient.
once you added any patient. You will be able to show all patient using "ShowAllPatient;" method. -> i want the Auto-increment ID Number to appear for each patient has been added.
And you will be able to call a patient to provide a hospital services for him/her using "GetNextPatient;" method.
I need to generate an Auto-increment Number for each (patient) has been added. (Auto-increment Number) but it just should be different for each patient. For example the first patient will have 1, The second patient will have 2. etc. The Auto-increment number should appear for each patient.

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?
Code:
#include<stdio.h>
int main(){
char str[50];
char rev[50];
printf("Enter Desired Text: ");
scanf ("%[^

Is it just my compiler?
struct Book{
string bookTitle;
string ISBN;
string author;
string publisher;
string dateAdded;
int qty;
double wholesale;
double retail;
};
What's the best way to store multiple of the above structure?Ideally, it would be with a binary output, but that isn't possible with the strings, unless I'm missing something. So that leaves me with two options.
-Create a second structure that has an outrageous char[] length, and then copy the data from the original structure to write/read to/from the file. The flaws I see in this is excess runtime with copying, and a larger amount of memory is temporarily needed. The positive I see is I can use binary output, which is easier.
-The second option is to just use an ASCII file, and put each element on it's own line, and then just use getline to read each line. The flaw I see in this is that I have to read the file into the structure, instead of just reading the structure and the file can be tampered with (Not a huge concern). The positive is the lack of negative from the above.
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:
Code:
#include <stdio.h>
#include <assert.h>
#include <fcntl.h>
#include <unistd.h>
#include <sys/types.h>
[Code] ....
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.
How data actually store in the File. Like do data store just in one line or at different places for example in array data store in adjacent memory block while in struct data store at different memory block.?

I'm having trouble understanding on how to actually store into a container from another class. Any simple example.
View 9 Replies View RelatedI have a class I use to store column data read from delimited text files.
Code:
class column_data {
// class functions here
public:
// initialize class members
column_data()
: header(""),
[Code] ....
Each column is read into the vector of string. Next the string data is copy converted to the vector of double or the vector of int depending on the data type. There can also be additional transformations of the data (normalization, scaling, etc) and the transformed data is copied to the transformed_double_data vector. I do end up with multiple copies of the data, but I can clear some of the vectors if I don't need all the versions of the data anymore. Each column object goes into a container like a vector of objects or map of objects depending on how I need to access the column data.
There are functions that calculate statistics on the data in the columns and the results are assigned to the object variables like validate_r2. There are separate statistics for each column, so it seems logical to store the results in the column object. This works well for statistics like validate_r2 (pearson's correlation coefficient).
The current issue is that I have other statistics like "pw50" that I need to calculate and store. The statistic is the percent within +/- 50 units and the request for pw50 is passed in from the command line. The issue is that there could be several of these and they can have more or less any value like, pw50, pw75, pw100, etc. Storing data like this doesn't fit into my scheme very well because I can't pre-declare a variable to hold the result for every possible option. I don't know in advance how many, if any, of these there will be. I was thinking of adding two vectors, one of string and one of double,
Code:
class column_data {
public:
// initialize class members
column_data()
: header(""),
type(""),
use(""),
validate_r2(0.0),
[Code] ....
For each of this type of statistic requested, I would push_back a label into the string vector and then put the result into the parallel position in the double vector. This seems like I would work, but there are probably some things that could be done with pointers that might be better. Another option would be a vector of objects where each object had a string value for the label and a double for the result. That would be more bullet proof as far as keeping the label and value together, but I have not ever nested objects in a class like that so I thought I would post. I don't know the syntax for declaring an object of class_b inside the definition of class_a. The need is to provide dynamic storage for an unspecified number of these statistics and a reliable way to retrieve the values using the label.
How I would store all the data. Also how would I access it after I store it. Side Note we are not allowed to use structures or objects.
For the purposes of this gradebook you should first provide a menu with the following options
-Add a new course Add a new student to a course Add grades for a student in a course Print a list of all grades for a student in a course Print a list of all students in a course Compute the average for a student in a course Compute the average for a course Store Gradebook (to a disk file) Load Gradebook (from a disk file)
-Each of these menu items should correspond to a function you will write.
-For the basic program each student will be represented by an ID number And each course by a course number
-Grades will be whole numbers only (no fractional part)
As indicated in the menu you will need to store and load using a disk file so that the data is retained.
Here are so limiting values in defining your data structures: Maximum Number of students (total) 100 Max number of courses 25 Max number of courses per student 4 Max number of grades per student per course 10

I serialize a XML file, and i have this values here:
public class ServiceConfig {
public List<DatabaseDescriptor> Databases { get; set; }
} public class DatabaseDescriptor {
[XmlElement("Name")]
[Code] ....
I have a form1 which is a datagrid view and get's updated like this:
dataGridView1.DataSource = xmlData.Databases;
Now i have a button: get tables, and it opens up form 2, there it's supposed to appear all the tables of the selected Database, when i click on the row i get the database name so i get all the list of Tables from
DatabaseDescriptor
where
DatabaseDescriptor.Name == name
(I get this when i select the row)
But then on the 2nd form, i also have 2 textbox so i add a new table, i add the tablename and id. the new value should appear in the datagridview of the tables, and when i close it and reopen it, it should be there. Maybe i should concatenate first the values or something, how do i do?
i need to create a new integer data type called BigInt to store a big big integer, which includes Dint(8 bytes) and Qint(16 bytes)
here is the hint/
typedef struct BigInt {
Int data[2];
}
How can i "scanf" and "printf" them????
void ScanBigInt(const char *format, BigInt &x)
if format is “%dd” -> input Dint, if format is “%qd”--> input Qint
void PrintBigInt(const char *format, BigInt x)
