C Program to Implement Selection Sort using Recursion

This C Program implements a Selection sort. Selection sort works by finding the smallest unsorted item in the list and swapping it with the item in the current position. It is used for sorting unsorted list of elements.

Here is the source code of the C program to display a linked list in reverse. The C program is successfully compiled and run on a Linux system. The program output is also shown below.

$ cc pgm18.c
$ a.out
Enter the size of the list: 5
Enter the elements in list:
23
45
64
12
34
The sorted list in ascending order is
12  23  34  45  64
