Adding element in sorted order in an array

I want to add the element in an array while entering it in a sorted manner. That means at the time of entering the new element in array, it will add its sorted state.

I have tried following examples, but I want to do it in an automatic manner. Can anyone help me, please?

my example

#include <stdio.h>
void main()
{
    int a[20], n, item, i;

    printf("Enter the size of the array");
    scanf("%d", &n);

    printf("Enter elements of the array in the sorted order");
    for (i = 0; i<n; i++)
    {
        scanf("%d", &a[i]);
    }

    printf("\nEnter ITEM to be inserted : ");
    scanf("%d", &item);

    i = n - 1;
    while (item<a[i] && i >= 0)
    {
        a[i + 1] = a[i];
        i--;
    }
    a[i + 1] = item;
    n++;

    printf("\n\nAfter insertion array is :\n");
    for (i = 0; i<n; i++)
    {
        printf("\n%d", a[i]);
    }
    getch();
}
