Write a program to Insert an Element to an Array at Valid Position
#include<stdio.h>
#include<stdlib.h>
#define MAX 5
int a[MAX], pos,
elem;
int n = 0;
void create();
void display();
void insert();
void main()
{
int
i;
printf("\nEnter
the number of elements: ");
scanf("%d",
&n);
if(n
!= 0)
printf("\nEnter
the elements: ");
for(i=0;
i<n; i++)
{
scanf("%d",
&a[i]);
}
insert();
display();
}
void display()
{
int
i;
if(n
== 0)
{
printf("\nNo
elements to display");
return;
}
printf("\nArray
elements are: ");
for(i=0;
i<n; i++)
printf("%d\t
", a[i]);
}
void insert()
{
int
i;
if(n
== MAX)
{
printf("\nArray
is full. Insertion is not possible");
return;
}
do
{
printf("\nEnter
a valid position where element to be inserted: ");
scanf("%d",
&pos);
}while(pos>n);
printf("\nEnter
the value to be inserted: ");
scanf("%d",
&elem);
for(i
=n-1; i>=pos ; i--)
{
a[i+1]
= a[i];
}
a[pos] = elem;
n = n+1;
}
Output:
Case 1:
Enter the number
of elements: 3
Enter the
elements: 11 22 33
Enter a valid
position where element to be inserted:
5
Enter a valid
position where element to be inserted:
1
Enter the value to
be inserted: 44
Array elements
are: 11
44 22 33
Case 2:
Enter the number
of elements: 5
Enter the
elements: 11 22 33
44 55
Array is full. Insertion is not possible
Array
elements are:
11 22
33 44 55
