It depends what language you are using and how the function is implemented. However, generally, you need to pass 4 arguments to the function:
1. A reference to the array.
2. The lower bound of the sub-array to be sorted (usually 0).
3. The upper bound of the sub-array to be sorted (usually n-1 for an array of n elements).
4. A binary predicate to perform comparisons between the elements (usually a less-than predicate).

Write c program to find median?
If you are using an array : sort using qsort() then take middle element.
How do you implement a quick sort in Haskell?
-- empty list is already sorted qsort [] = [] -- choose first element as pivot, -- put all elements less than x on the left, -- put all elements greater than x on the right, -- recurse on both sides qsort (x:xs) = qsort (filter (< x) xs) ++ [x] ++ qsort (filter (>= x) xs)
How do you sort the given contents of an array?
You would sort the given elements of an array by a bubble sort or heap sort code!!
How many types of sorting array in C programming?
You can sort an array with any method you want, but there is a built-in qsort function, declared in stdlib.h (see the attached link).bubble sort, quick sort, insertion sort, merge sort, radix sort and lot more..merge sort is the most efficient one..
Can you modify the bubble sort algorithm to search to sort an array of characters instead of array of integers?
The bubble sort algorithm can be applied to an array of characters. Every character can be translated to an integer equivalent via the ascii table

What is sort in C programming pls ans. this... thanks?
There is a built-in qsort function, see stdlib.h
Simple c program for quicksort?
#include<stdio.h> void print(int a[]) { int i; for( i=0;i<=8;i++) { printf("%d ",a[i]); } } int Qsort(int data[], int left, int right) { int mid,tmp,i,j; i = left; j = right; mid = data[(left+right)/2]; do { while (data[i] < mid) i++; while (mid < data[j]) j--; if (i <= j) { tmp = data[i]; data[i] = data[j]; data[j] = tmp; i++; j--; } } while (i <= j); { if (left < j) Qsort(data,left,j); if (i < right) Qsort(data,i,right); } } main() { int array[]={12,99,4,99,12,12,13,10,13}; printf("Before sort:\n\n"); print(array); Qsort(array,0,8); printf("\n\nAfter sort:\n\n"); print(array); printf(""); }
How do you write an algorithm that puts a list of names in ascending order?
In C language, you can use the string comparing method/*try it, you,ll understand, anr this is not a example done by me. this is the example which i used to learn it*/#include #include #include /* qsort int comparison function */int int_cmp(const void *a, const void *b){const int *ia = (const int *)a; // casting pointer typesconst int *ib = (const int *)b;return *ia - *ib;/* integer comparison: returns negative if b > aand positive if a > b */}/* integer array printing function */void print_int_array(const int *array, size_t len){size_t i;for(i=0; iprice - 100.f*ib->price);/* float comparison: returns negative if b > aand positive if a > b. We multiplied result by 100.0to preserve decimal fraction */}/* qsort struct comparision function (product C-string field) */int struct_cmp_by_product(const void *a, const void *b){struct st_ex *ia = (struct st_ex *)a;struct st_ex *ib = (struct st_ex *)b;return strcmp(ia->product, ib->product);/* strcmp functions works exactly as expected fromcomparison function */}/* Example struct array printing function */void print_struct_array(struct st_ex *array, size_t len){size_t i;for(i=0; i
Sorting an array in PHP without using sort function?
plz as soon as possible give me the program for shorting an array in asscending order without using any sort function in c++
Which is the best sorting methad?
There is no one best sorting method. The qsort() function is a good all rounder. The best sorting method depends on what you want to sort and how many items you need to sort and can only be determined by actual testing.

How do you sort variable in ascending or descending order both in php?
Assuming that the values are stored in an array, you can use the php function sort($array) to sort ascending, and rsort to sort descending. The following link gives a table that lists all of the built in PHP sort functions: http://php.net/manual/en/array.sorting.php
Sorting of array through function in java programming?
// the build in sorting functions in Java will sort pretty much any array // of Comparable objects or primitives Arrays.sort(someArray);
How do you sort array in php without use of sort function?
$arr=array(2,5,4,6,7,8,1); for($i=0;$i<count($arr);$i++) { for($j=$i;$j<count($arr);$j++) { if($arr[$i] > $arr[$j]) { $temp=$arr[$i]; $arr[$i]=$arr[$j]; $arr[$j]=$temp; } } }
When quick sort is preferred?
When you want to sort an array.
