100% program to insert a element from given location in the array

#include <stdio.h>

    printf("\n enter no of elements in the array with max limit of 19:"); /*the max limit u enter should be 1 less than array size (of 20) used (here) in the initial declaration becoz after inserting the element overall size should not cross initially declared size, which is 20 here*/
    scanf("%d",&n);
    for(i=0;i<n;i++)
    {
        printf("\n enter the (integer) element a[%d]:",i);

    a[location-1]=nayA;
    printf("\n the elements in the array after deletion of 1 element are:\n");

enter no of elements in the array with max limit of 19:4

enter the (integer) element a[0]:2
enter the (integer) element a[1]:4
enter the (integer) element a[2]:7
enter the (integer) element a[3]:-1
enter the location where new element has to be inserted:
3
enter the integer element to be inserted:0
the elements in the array after deletion of 1 element are:

a[0]=2       a[1]=4       a[2]=0       a[3]=7       a[4]=-1
