Selection Sort :- The selection Sort is basically the selection of the position of the element from the beginning with the other elements.Elements are compared and exchanged based on position and then the selection position is moved to the next position until it reaches the end. As you can see that we have entered 6 elements in random order and the program sorted them in ascending order by using selection sort algorithm which we have implemented in the program. You can also modify this same program to sort the elements in descending order as well. After executing the nested loop, we will obtain an array in descending order arranged elements. To sort array we select an element and place it to its correct position by comparing with subsequent elements. There are numerous logic to sort given set of numbers. Moving on with this article on Sorting Algorithms In C, Selection Sort. Write a program to sort an array elements in descending order using selection sort. Sorting is useful in large data collection to optimise the data searching to a very high level. Online C++ arrays programs and examples with solutions, explanation and output for computer science and information technology students pursuing BE, BTech, MCA, MTech, MCS, MSc, BCA, BSc. Selection sort first finds the smallest element in the unsorted array and swaps it with the first element. Arranging the array’s elements from largest to smallest is termed as sorting the array in descending order. And each data item is called an element of the array. Selection Sort in C. For example- See the following list of alphabets and then sorted list after arranging in alphabetical order.
