1. Sort an array of integers

#include <stdio.h>

int main()
{
    int n, i, j, k, temp;
    printf("Enter the number of elements of the array : ");
    scanf("%d", &n);
    int arr[n];
    printf("Enter the %d integers : ", n);
    for(i = 0; i < n; i++)
        scanf("%d", &arr[i]);

    for(i = 0; i < n - 1; i++)
    {
        for(j = 0; j < n - i - 1; j++)
        {
            if(arr[j] > arr[j + 1])
            {
                temp = arr[j];
                arr[j] = arr[j + 1];
                arr[j + 1] = temp;
            }
        }
    }

    printf("\nThe sorted array of integers : ");
    for(i = 0; i < n; i++)
        printf("%d ", arr[i]);
    printf("\n");
    return 0;
