C/C++ :: Sorting Regard To Nth Term
Nov 7, 2014I know how to sort an array but how I can sort an array regard to nth term.
Example:
2 --> nth digit
4 45 62 1 900 105 -->inputs
Output:
001
004
105
900
045

C :: Algorithm To Find Kth Term Of A Series
Dec 8, 2014I want to write an algorithm to find the kth term of a series given by the following recursive formula:
a_0=1 and a_(k+1)=a_k+1/k!
My code (part of it responsible for calculating the value of a series) does not want to compile:
Code:
float series(int n)
{
float F0 = 1;
float F;
unsigned int i;
if (n == 0)
return(1);
[Code]...
thus my question is why it does not want to work properly and what should i change (for certain factorial function is OK)?

C++ :: Define A New Member Method Which Calculates Value Of Term And Display It
Jul 30, 2012A class called 'sample' with the data a, b and c and two methods as defined below. Define a new member method 'term()' which calculates the value of the term (2b - 4ac) and displays it.
Define the method outside of the class definition. Write the main method to create an array of 2 objects called D of class 'sample' and display the values and find the solution to the term (2b - 4ac)
My code so far:
#include <iostream>
using namespace std;
int term(int a, int b, int c) {
int result;
result = (2*b - 4*a*c);
[Code] ....
Problem: I keep getting error messages, here is a look at the ones i'm getting.
error: ISO C++ forbids declaration of 'cout' with no type.
error: expected ';' before '<<' token.
error: new types may not be defined in a return type
error: expected unqualified-id before '{' token.
C/C++ :: Error C2064 / Term Does Not Evaluate To A Function Taking 1 Arguments
Aug 7, 2014i'm implementing a templated function callback.
I get this error:
"error C2064: term does not evaluate to a function taking 1 arguments"
I'm not sure why.
Here's the code for the template function in the timer class header:
template<class T>
void TimerEvent(DateAndTime DateTime, std::function<void(T)> Callback);
Now the class body:
template<class T>
void GameTimer::TimerEvent(DateAndTime DateTime, std::function<void(T)> Callback)
{
DateAndTime time;
time.Now(false);
if (time.Compare(DateTime) == 1)
Callback(T);
}
and calling the class in the Engine:
int test1(int a)
{
}
void Main()
{
gameTime.TimerEvent<int>(gh, test1(1));
}

C++ :: Before And After Sorting Net Pay
May 14, 2014I'm working on a program for payroll that will calculate and display a list of payroll variables (including net pay) then run again sorting the net pay. So the program should run once display all the variables with the net pay not sorted then run a second time with the net pay sorted.
I've written a program. It is working. But it only runs once and it and it only displays the results with the net pay after it's sorted. What I need to do in order to get it to run a first time without sorting the net pays before it runs the second time sorting the net pays.
My input file reads:
1645JohnDoe4025.00

C :: Sorting Four Numbers

C++ :: Sorting First And Last Name With Netpay
May 14, 2014So my ongoing work sorting my net pay program continues.I've got it working to the point where it sorts the net pay and only the net pay. I've been told I can comment out the other variables (hours worked, hourly rate, etc...) with the exception of First Name, and Last Name which I need to sort along with Net Pay.I need to sort First Name and Last Name along with Net Pay so that while Net Pay is being sorted it still corresponds to the same individual.
Right now as I'm only sorting Net Pay and individuals end up with different Net Pays as the sorting occurs. This is the programs current output (Pre Sorting)

C++ :: Map Inside A Map Sorting
Feb 21, 2015I have a map which contains a multiset and another map
std::map<std::multiset<int>, std::map<int, int> >
And I need to sort the whole map according to the mapped value of the inside map, then output the data from the keys i.e. from the multiset and the first value of the inside map. I have tried to create a vector of pairs
std::vector<pair<std::map<:std::multiset<int>, std::map<int, int> >, int> >
and populate the first element with the map and where the second integer of the pair will be the mapped value to sort. I have tried iterating over the map to populate the vector but I'm not sure how to do so.
C# :: Sorting A ListView?
Apr 22, 2014at the moment I lack access to the pc with the code on it, so for now I will try to keep my question basic.
now here is my problem: I have a listview witch is populated by user input(lets say for the ease of argument that the input is "first-name" "last-name" and "e-mail adres") all of with get there information from textboxes.
then all the information gets stored in a list and on closing that list is stored in a xml-file in the following format
<Root>
<Data>
<first-name>
Samual
[Code].....
the input, saving and loading is no problem. when you open the file this listview is in view = List so that you only see the last-name(I prefer it that way since I know how to code that) and when you click it it fills the textboxes with the corresponding information.
what I am trying to figure out it how to make it that it sorts itself(preferred sorting when something is changed).
I tried the ListView.sorting = SortOrder.Ascending; when I do it that way it messes up the corresponding information(is it clear what I mean or do I need to add an example).

Basically what i am trying to do is that sort the names of 10,000 movies and then write those names to a text file. It gives an error in the nested loop by underlining arr and tells that no suitable conversion function from std::string to const char* exists.
C :: File Handling Sorting
Mar 6, 2015I am accepting the word from user and arranging it in ascending order like in dictionary in a file . I am doing this by comparing the user entered word from existing word in the file . All the word which is smaller then user entered word is copied to another file "temp.txt" , then the user word is printed and then the remaining word ( which are larger) from "abc.txt" to "temp.txt" . But program close as soon as i enter the second word
Code:
#include<stdio.h>
#include<string.h>
main() {
FILE *fp,*ft ;
fp = fopen("abc.txt","r+");
ft = fopen("temp.txt","r+");
[Code]....

C :: Sorting Has To Be Based On Int Field
Feb 16, 2013I have a file which has records with 2 fields--one int and one float..what is the best way to sort it?
The sorting has to be based on the int field(the first field) (each time the program runs the file might end up with some hundreds of records).
C :: Selection Sorting A 2D Array
Feb 13, 2013Selection sorting a 2D array . Let's say i have an array like

1 2 3 //3 elements
1 //1 element
And I want to do a selection sort it in descending order which the row with 5 elements will come first then 4 then 3 and so on. So that it would look like this
1 2 3 4 5
1 2 3 4
1 2 3
1 2
1
Code:

C :: Sorting Array Of Size 10
Nov 18, 2013I am trying to sort an array of size 10. If I was given:
Code: int List[Size] = {29, 11,12,10,3,26,13,15,19,2};
I need the program to sort all the odd integers and put the even integers to the back of the array. Like so:
Index: 0 1 2 3 4 5 6 7 8 9
Value:29 11 3 13 15 19 12 10 26 2
And it returns the number of even integers in the List. In this case it returns 4. All I am given to start with is
Code:
int evensToRead(int* const List, const int Size){
//body
}
C :: Sorting Words Alphabetically
Dec 10, 2014I've tried searching for answers around the web but everyone is using syntax that We haven't been taught before in class yet. I understand that the string library is probably the most efficient way of doing this but is there a way without using that library? Like using if, for, while etc. instead?
I've been told that using anything else other than the string syntax is far to complex but I think the more complex it is the more I will understand it.
C :: Sorting 2D Array By Column
