C++ documentation

Write a recursive function to sort an array of integers into ascending order using the following idea: place the smallest element in the first position, then sort the rest of the array by a recursive call. This is a recursive version of the selection sort. (call an auxiliary function that finds the index of the smallest item in the array. Make sure that the sorting function itself is recursive. Any auxiliary function that you use may be either recursive or iterative.) Embed your sort function in a driver program to test it.
