c sort array function
void sort(ptr, n); should just be sort(ptr, n);. I could be wrong on this, but I believe in a C compiler, the first form is interpreted as a function prototype and the second an actual function call., However, it is very likely that common implementation will use algorithm that yields average case O(nlogn) time complexity (which is optimal for sorting by comparison). You can use this to sort any kind of array (even struct ) - but you must provide a co, Now your lesson about sorting becomes "how does this work"? You start by explaining memory layout and arrays. You can't do much in C until you know this anyway. Then you explain what a void pointer is and why the qsort function needs to kno, qsort() is the function you're looking for. You call it with a pointer to your array of data, the number of elements in that array, the size of each element and a comparison function. It does its magic and your array is sorted in-place. An example fo, When you declare int arr[20];. you can say "arr is an array of 20 integers". But arr is a pointer to an integer as well, pointing to the first integer in a row of 20. So de-referencing *arr is an integer, the same as arr[0] in fact. This means ,9.3 Array Sort Function. To sort an array using an arbitrary comparison function, use the qsort function. The prototype for this function is in stdlib.h . Function: void qsort (void * array , size_t count , size_t size , comparison_fn_t compare ). Prelimi,Parameters. base − This is the pointer to the first element of the array to be sorted. nitems − This is the number of elements in the array pointed by base. size − This is the size in bytes of each element in the array. compar − This is the function that ,Searching and Sorting. This chapter describes functions for searching and sorting arrays of arbitrary objects. You pass the appropriate comparison function to be applied as an argument, along with the size of the objects in the array and the total number ,Code, Example for Sorting of array elements using a function in C Programming. ,Standard C library provides qsort function that can be used for sorting an array. Following is the prototype of qsort() function. // Sort an array of any type. The parameters are, base // address of array, size of array and pointer to // comparator functi
