its the algorithm here..

INSERT(ARR,N,K,ITEM) //N-NO OF ELEMENTS,K-POSITION,ITEM-TO BE INSERTED
SET J:= N
REPEAT STEPS 3 AND 4 WHILE J>=K
SET ARR[J+1]:=ARR[J]
SET J:=J-1
SET ARR[K]:=ITEM
SET N:=N+1
EXIT

Dude..you can use these functions for insertion and deletion..

num : number to insert/delete
pos : position where it will be inserted/deleted

Example taking array of size 5...

Insertion Function:-

``````void insert(int num, int pos)
{
for(int i=4; i>=pos;i--)
arr[i]=arr[i-1];
arr[i]=num;
}``````

Deletion Function :-

``````void a_delete(int pos)
{
for(int i=pos; i<=4;i++)
arr[i-1]=arr[i];
arr[i-1]=0;
}``````
