Data Structure - Insertion Sort Example using C program

/*Insertion Sort - C program to sort an Array 
in Ascending and Descending Order.*/
 
#include <stdio.h>
 
#define MAX 100
 
int main()
{
    int arr[MAX],limit;
    int i,j,temp;
     
    printf("Enter total number of elements: ");
    scanf("%d",&limit);
     
    /*Read array*/
    printf("Enter array elements: \n");
    for(i=0; i<limit; i++)
    {
        printf("Enter element %3d: ",i+1);
        scanf("%d",&arr[i]);
    }
     
    /*sort elements in Ascending Order*/
    for(i=1; i<(limit); i++)
    {
        j=i;
        while(j>0 && arr[j]<arr[j-1])
        {
            temp=arr[j];
            arr[j]=arr[j-1];
            arr[j-1]=temp;
             
            j--;
        }
    }
 
    printf("Array elements in Ascending Order:\n");
    for(i=0; i<limit; i++)
        printf("%d ",arr[i]);
     
    printf("\n");
         
    /*sort elements in Descending Order*/
    for(i=1; i<(limit); i++)
    {
        j=i;
        while(j>0 && arr[j]>arr[j-1])
        {
            temp=arr[j];
            arr[j]=arr[j-1];
            arr[j-1]=temp;
             
            j--;
        }
    }
 
    printf("Array elements in Descending Order:\n");
    for(i=0; i<limit; i++)
        printf("%d ",arr[i]);
         
    printf("\n");
     
    return 0;
}

Output

 
    Enter total number of elements: 10
    Enter array elements: 
    Enter element 1: 40 
    Enter element 2: 10 
    Enter element 3: 100
    Enter element 4: 20 
    Enter element 5: 90 
    Enter element 6: 60 
    Enter element 7: 80 
    Enter element 8: 70 
    Enter element 9: 30 
    Enter element10: 50 
    Array elements in Ascending Order:
    10 20 30 40 50 60 70 80 90 100
    Array elements in Descending Order:
    100 90 80 70 60 50 40 30 20 10
