C :: Radix Sort Function To Sort Array Of 64 Bit Unsigned Integers
Aug 19, 2013Example radix sort function to sort an array of 64 bit unsigned integers. To allow for variable bin sizes, the array is scanned one time to create a matrix of 8 histograms of 256 counts each, corresponding to the number of instances of each possible 8 bit value in the 8 bytes of each integer, and the histograms are then converted into indices by summing the histograms counts. Then a radix sort is performed using the matrix of indices, post incrementing each index as it is used.
Code:
typedef unsigned long long UI64;
typedef unsigned long long *PUI64;
PUI64 RadixSort(PUI64 pData, PUI64 pTemp, size_t count) {
size_t mIndex[8][256] = {0};
/* index matrix */
PUI64 pDst, pSrc, pTmp;
size_t i,j,m,n;
UI64 u;

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>

int term(int a, int b, int c) {
int result;
result = (2*b - 4*a*c);

Problem: I keep getting error messages, here is a look at the ones i'm getting.

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)

}
and calling the class in the Engine:
int test1(int a)
{
}
void Main()
{
gameTime.TimerEvent<int>(gh, test1(1));

C++ :: How To Sort Integer Array
Jul 28, 2013I want to sort an array like Myarray[3][4] based on the second column while other correspondent rows exchange consequently.
My array is as follows:
3 8 7 2
9 12 0 4
12 2 14 1
I want to sort it based on the second column using “std::qsort" or "std::sort” or other quick method that would lead to the following :
12 2 14 1
3 8 7 2
9 12 0 4
C :: Array Sort With Qsort By Using Two Criteria?
Sep 26, 2014I am starting a new thread. So I try to sort an array with qsort and then save the new order, so this means if I have a list like:
4 3 7 2 [0] [1] [2] [3],
after sorting it becomes:
2 3 4 7 [3] [1] [0] [2] <== this is what I want to have!
Which works fine, with following code:
void qsort_my(int *a, int l, int r, int *array_order) {
int j;
if( l < r ) {
j = split( a, l, r, array_order);
qsort_my( a, l, j-1, array_order);
qsort_my( a, j+1, r, array_order);
[Code]...
I tried to add the criteria :
(if (a[i] != a[j] || (a[i] == a[j] && array_order[i] > array_order[j])))
before calling switch_pos, but it is not working since sometimes you swap two numbers like:
11 9 15 9 <= here the 11 and 15 are swapped, but the two 9's will never be swapped <=> compared.I mean I could run it again with the array_order on the first parameter position, but this would increase my runtime enormously!
C :: Sort Array By Function To Get Max Number
Mar 6, 2015I have this code(homework) i've been working on for several days i couldn't fix this error.
Question is: to write a sort program in c . Ineed to ask user for how many numbers to be sorted(n) ask again for values. The approach of sort is this:
1- store n in temporary var (temp)
2- search for largest number in array (0 until temp-1)
3- switch the fied that store largest with field indexed by (temp-1)
4- temp-- (decrement)
5- repeat steps 2 to 4 until temp is 1
the program then prints the numbers of array on screen in one line. I also should use a function getMax(int *list , int n) that determines largest value and returns its location in that array
list : is the array
n: number of elements
Code:
#include<stdio.h>
int getMax(int *list, int n); //definition of getMax function
int main(void) {
int n,i;
[Code] .....
so i tried to sort this array
Code:
input 2 7 9 4 3 1 6 5
The out put should be : 9 7 6 5 4 3 2 1
instead it prints : 7 9 2 4 3 1 6

C/C++ :: Dynamically Allocate Array And Sort
Aug 31, 2014Write a program that dynamically allocates an array large enough to hold a user-defined number of test scores. Once all the scores are entered by the user, the array must be passed to a function that sorts them in ascending order. It must use another function that calculates the average score. The program should display the sorted list of scores and average with appropriate headings. The program must use pointer notation instead of array notation. Validation: Do not accept negative numbers for test scores; keep prompting the user for a new grade. Do not accept negative numbers for the number of scores the user wants to enter.
#include <iostream>
#include <iomanip>
using namespace std;
// Function prototypes
double getAverage(int*, int);
void sortScore(int *,int );

I have no errors in my code but when i run it and i enter a positive interger it just goes into a loop to enter a positive number.

C :: Sort Array And Save New Order Of Elements
Sep 25, 2014So I try to sort an array with qsort and then save the new order, so this means if I have a list like:

after sorting it becomes:
2 3 4 7
[3] [1] [0] [2] <== this is what I want to have!
Code:
void qsort_my(int *a, int l, int r, int *array_order) {
int j;
if( l < r ) {
j = split( a, l, r, array_order);
qsort_my( a, l, j-1, array_order);
qsort_my( a, j+1, r, array_order);

But my problem is that the list gets sorted, but the indexes do strange stuff. When I run with this list:
4 8 14 1 2 1 22 12 2 14
Pos: 0 1 2 3 4 5 6 7 8 9
I get:
1 1 2 2 4 8 12 14 14 22
Pos: 1 0 1 0 0 5 7 6 5 6
And with some printfs I noticed, the first two calls of split it is fine but then strange things start to happen, what I do wrong?

C++ :: Selection Sort On Array Of Class Objects?
Jan 24, 2013I have written a selection sort algorithm to go sort an array of class objects by age in ascending order, the problem is that the output being given does not match what i think the code should do. when the program runs the 3 records are added to the array and when they are sorted should be outputed in ascending order, the problem is that with my code the last 2 are sorted properly but the first element does not seem to move, it remains the same as the original unsorted value.
My code for the selection sort function and the display method are below:
void selectionSort() {
int i, minIndex, minValue;
for (i = 0; i < (arrlength - 1); i++) {
minIndex = i ;
