My whole code is included below, although what is really important to me is only the first two functions, the quicksort and the partition...Whenever I build this program, it keeps returning an error for the calling of the partition function, citing that the first variable is in an improper format... I don't know why it's not working though..
Whole Code:
#include <iostream>
#include <string>
#include <algorithm>
using namespace std;
template <class T>
void quicksort(T arr[], int start, int end)
I've been trying to implement a quick sort algorithm for linked list but when i try to run it with 1000000 values my compiler tells me its running too long and ends up not finishing. However when i run it with 10 values it seems to work fine.
I am trying to sort a linked list using quick sort in C. Here is my code--Actually, first I am inserting data in the list from a file. For a small file, it's working fine. But for large file it's just not working.
I'm tinkering with a serial quick sort algorithm. Normally I use qsort() but I wanted to test this.
Somehow I loose the highest number. I can't see where I drop it.
Code: // function to quicksort, leave them in front of qsort. void swap(float_t *left, float_t *right){ float_t temp; temp = *left; *left = *right; *right = temp;
I'm trying to sort the elements in a linked list which contain a variable amount of data in any given case. In the sample code, the code is more static, but I plan on adding it to much more dynamic code once I have it figured out. My main problem is that I am not sure how to sort the linked list while still keeping the correct pointers to the nodes. I thought about writing my own custom quick sort instead of using the C-standard library function, but how I would keep the pointers to the next nodes correct eluded me. Here is my code so far :
I am having some problem with my quick sort problem. My program is supposed to create 5 arrays with 5,10,15,and 20 random integers, respectively. Then it should sort those arrays, where the numbers are bigger or smaller than the middle element in the original array! The program I wrote should do that but, its not! The program just keeps running infinitely!
#include <iostream> #include <cstdlib> using namespace std; void p(int k[],int left, int right) { int i = left, j = right;
Example 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;
I'm trying to implement a simple template array class, but when i came into the operator< i actually have to use a template :
my code is something like :
template<typename _Type, std::size_t _Size> class array { public :
[Code] ......
but i am having an error of shadows template param 'class _Type' is it w/ the name conflict between the array template parameter and the function template parameter ?

I have a generic template class with another template in one of its types. Now I want to specialize one of its methods for a particular (template) class, which leads to a compile error, however.
GCC ends with: :35:27: error: type/value mismatch at argument 2 in template parameter list for ‘template<class Type, template<class> class O> class Foo’ :35:27: error: expected a class template, got ‘Obj2<Type>’
What is wrong with the specialization? Can it even be achieved and how (if so)?
how I want the code to look. Only problem is it doesn't work (Line 11). I have some experience with templates but I'm not a pro.
Basically I want the "Channels<3>" to be a type that I can use to specify a Cable with similar to vector<float/int> it would be Cable<Channels<2 or 3>>.
What have I messed up with the syntax?
#include <iostream> #include <vector> using namespace std;
where 'g()' returns an object of the element type. However, the compiler is claiming, no matter how I write a call to the overload, the original template is selected and/or the overload is invalid, depending on the various ways I attempt to write said overload.
You will write a program that uses a multidimensional array having 3 rows and 8 columns and sorts each of the rows using both a bubble sort and a selection sort.
You must declare the array inside of main. You will have a for loop containing the calls to bubbleSort and selectionSort. You need to pass into function bubbleSort and selectionSort the following: 1) each column of the multidimensional array, 2) the size of the column, and 3) a particular row number of the multidimensional array to be used for printing out the "pass" shown on the following pages.
I keep getting an error that the identifier for bubbleSort and selectionSort is not found. (Error C3861) Also, I feel like I'm missing something in int main() to get it to sort properly.
# include <iostream> using namespace std; int main() {
I have tried several variants on this code to no avail. Outer is in a header, along with the extern template statements, and the specializations after main are in their own cpp file. Main is in a different cpp file.
What do have to do to make this work? I cannot bring the definitions of f() into the header, and they will be different for different template parameters. Ideally, I want Test to remain a private member of Outer, though this can change if it's the only option.
And then have another template function declaration for all the attractor functions where I pass the same template value as in the first one.
As you can see, I'm calling another functions inside called attractors(_tmp). I know that one way around it could be to get rid of that function and just do all the logic inside of each if statement. Is there any way to pass the same template function parameter within a template function parameter?
/** This class build the singleton design pattern. Here you have full control over construction and deconstruction of the object. */ template<class T> class Singleton

I am getting error at the assertion points when i call to the class as follows:
From my tests I found the problem to be somewhere in the Mantissa part that converts it to binary.
bool xsDLL GetHexFromSF_IEEE754( void* to, Text from, ui08 tSize ) { from.UpperCase(); int db = 0, dB = 0, dBEnd = tSize, dBLast = ( tSize - 1u ), dbEnd = dBEnd * 8; ui08 *data = reinterpret_cast< ui08* >( to ); for ( ; dB >= 0; --dB ) data[ dB ] = 0u;

Adjustments made, still having problems though. After finding a more useful resource [URL] ..... I got the function looking more like it should but am still having problems...
according to here [URL] .... ô in decimal is 147 and print ô using alt 147
and here [URL] .... ô in dec is 244 but prints ⌠ using alt 244
put on console
char c = ô; cout << (int)c << endl;
prints -109 and print m using alt -109
I am using alt to test char output. Why I'm getting a negative value? Which of the tables are correct? I have string of char that I want to print in hex. I get a hex string but the hex value don't correspond to any of the two tables on the websites because the console converts special char to negative values.
I am having problems with converting a CString to an int and than doing checks on the int to see if it is in a particualr range.Below is what I am doing.
CString numstr = "28" int num = atoi(numstr); BOOL valid = TRUE; if(num < -32,768 { valid = FALSE; }
For some reason when running the above code the if statement is executed but it should not be becasue 28 is not less than -32,768. Why this is happening, I am not seeing the reason for this at all!! The num variable is being assigned the correct value.
