Unknown said selection sort write a c program to perform selection sort on an array of n elements. The selection sort algorithm is based on the idea of finding the minimum or maximum element in an unsorted array and then putting it in its correct position in a sorted array. Repeatedly searches for the largest value in a section of the data moves that value into its correct position in a sorted section of the list. This sorting algorithm is an inplace comparisonbased algorithm in which the list is divided into two parts, the sorted part at the left end and the unsorted part at the right end. From the bubble sort it was obvious that the sorting isnt efficient for larger list, even for a list more than 100 numbers although you wont see any difference on a good machine. To sort an array in ascending order using selection sort technique in c programming, you have to ask to the user to enter the array elements, now start comparing the array elements, on found, start swapping with the help of temp variable, place first number in the temp and second number in the first. Find the minimum element again in the remaining array2, n and swap it with the element at 2nd position, now we have two elements at their. Replace the smallest element with the array element placed at position i. Before going through the program, lets see the steps of insertion sort with the help of an example. Selection sort is an algorithm that works by selecting the smallest element from the array and putting it at its correct position and then selecting the second smallest element and putting it at its correct position and so on for ascending order.
A selection sort is a sorting algorithm which finds the smallest element in the array and swaps with the first element then with the second element and continues until the entire array is sorted. Insertion sort algorithm picks elements one by one and places it to the right position where it belongs in the sorted list of elements. The results of insertion sort for each pass is as follows a list of sorted elements now. The purpose of this program was just to demonstrate how these different sorting algorithms can be implemented in c language. C program for insertion sort programs and tutorials. C programs in selection sort, the smallest element is exchanged with the first element of the unsorted list of elements the exchanged element takes the place where smallest element is initially placed.
The algorithm divides the input list into two parts.
