Sample C Program To Insert An Element In An Array.

3. /* Program for insertion of an element in an array*/

#include <stdio.h>
#include <conio.h>
#include <stdlib.h>
#define S 7

main()
{

int arr[10];
int i, pos, num, j;
clrscr();

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

clrscr();
printf(" \n\nArray is \n\n ");

for( i = 0; i < S; i++ )
     printf(" %2d ", arr[i] );

printf(" \nEnter the element which you want to insert\n ");
scanf(" %d ", &num );
printf(" \nEnter the position (first is 0)\n " );
scanf("%d", &pos);

if( pos > = 0 && pos <= 9)
  {
     for( j = S;j > pos; j-- )
           arr[j] = arr[j-1];

     arr[j] = num;
}
else
  {
      printf(" Wrong position selected\n ");
      getch();
     exit(1);
  }

printf(" Array after insertion\n ");
for(i = 0; i < S; i++ )
     printf(" %d ", arr[i]);

getch();
}


OUTPUT:

Enter arr[0] element: 4
Enter arr[1] element: 7
Enter arr[2] element: 3
Enter arr[3] element: 6
Enter arr[4] element: 8
Enter arr[5] element: 4

Array is

4 7 3 6 8 4

Enter the element which you want to insert

3

Enter the position (first is 0)

4

Array after insertion

4 7 3 6 8 4 4
