Quicksort, invented by Tony Hoare in 1959, is one of the fastest sorting algorithms. However, conventional implementations have some weak points, including the following: swaps to exchange two elements are redundant, deep recursive calls may encounter stack overflow, and the case of repeated many elements in input data is a well- known issue. This paper improves quicksort to make it more secure and faster using new or known ideas in C language.
