c sort array function
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
