SYBCom(CA) DS Practical Slip 5 Q.B

Write a ‘C’ program to accept and sort n elements in ascending order using Selection sort method.

#include <stdio.h>

int main() {
    int n, i, j, minIndex, temp;

    printf("Enter number of elements: ");
    scanf("%d", &n);

    int arr[n];

    // Accept elements
    printf("Enter %d elements:\n", n);
    for(i = 0; i < n; i++) {
        scanf("%d", &arr[i]);
    }

    // Selection Sort (Ascending Order)
    for(i = 0; i < n - 1; i++) {
        minIndex = i;
        for(j = i + 1; j < n; j++) {
            if(arr[j] < arr[minIndex]) {
                minIndex = j;
            }
        }
        // Swap elements
        temp = arr[i];
        arr[i] = arr[minIndex];
        arr[minIndex] = temp;
    }

    // Display sorted array
    printf("Sorted array in ascending order:\n");
    for(i = 0; i < n; i++) {
        printf("%d ", arr[i]);
    }

    return 0;
}
