That is why beginning programmers often overlook quicksort as a viable option because of its T(n^2) worst-case running time, which could be made exponentially unlikely with a little effort. In fact, quicksort is the currently fastest known sorting algorithm and is often the best practical ...
Implementing QuickSort in C Here, we will be implementing quicksort in C by taking the first/low element as the pivot element. We will ask the user to select the array’s length and then the values of the elements in the array. Next, we will use the partition() function and define t...

I'm going to assume that you're aware of qsort (C implementation of quicksort) and std::sort (C++ sorting routine). Therefore, you are doing this as a programming exercise. There's a reinventing-the-wheel tag for that if you happen to do something similar in the future. using name...
