C Program for Selection Sort
The selection sort algorithm sorts an array by repeatedly finding the minimum element (considering ascending order) from unsorted part and putting it at the beginning. The algorithm maintains two subarrays in a given array.
1) The subarray which is already sorted.
2) Remaining subarray which is unsorted.
In every iteration of selection sort, the minimum element (considering ascending order) from the unsorted subarray is picked and moved to the sorted subarray.
// C program for implementation of selection sort #include <stdio.h> void swap(int *xp, int *yp) { int temp = *xp; *xp = *yp; *yp = temp; } void selectionSort(int arr[], int n) { int i, j, min_idx; // One by one move boundary of unsorted subarray for (i = 0; i < n-1; i++) { // Find the minimum element in unsorted array min_idx = i; for (j = i+1; j < n; j++) if (arr[j] < arr[min_idx]) min_idx = j; // Swap the found minimum element with the first element swap(&arr[min_idx], &arr[i]); } } /* Function to print an array */void printArray(int arr[], int size) { int i; for (i=0; i < size; i++) printf("%d ", arr[i]); printf("\n"); } // Driver program to test above functions int main() { int arr[] = {64, 25, 12, 22, 11}; int n = sizeof(arr)/sizeof(arr[0]); selectionSort(arr, n); printf("Sorted array: \n"); printArray(arr, n); return 0; } |
