Given problem states that, there will be an existing array, programmer need to insert the element at a particular position in the array

1. Write a program to insert an element
into an array at a given position.

2. Agenda
1. Program in c++
2. Array declaration and definition
3. Insert new element at the specified position
4. Print the array
1. Before Insertion
2. After Insertion

3. Logic
• Given array for example:
• arr[]={1,2,3,4,5}
• Specify position at which position the num. to be
present ex:2
• Enter what element to be inserted:6
• Loop:
• for(i=n; i>pos-1;i--)
• { arr[i]=arr[i-1]}
• arr[pos-1]=ele
• Print Array before insertion and after insertion

4. Let’s See Practically by writing the
program

5. • #include<iostream.h>
• #include<conio.h>
• void main()
• {
• int a[100],ele,n,i,pos;
• clrscr();
• cout<<"Enter the size of array"<<endl;
• cin>>n;
• cout<<"Enter the elements of array"<<endl;
• for(i=0;i<n;i++)
• {
• cin>>a[i];
• }
• cout<<"Enter the position to insert element"<<endl;
• cin>>pos;
• if(pos<n)
• {
• cout<<"Enter the element to be inserted"<<endl;
• cin>>ele;
• cout<<"Array before insertion:"<<endl;
• for(i=0;i<n;i++)
• {
• cout<<a[i]<<" ";
• }
• cout<<endl;
• for(i=n;i>pos-1;i--)
• {
• a[i]=a[i-1];
• }
• a[pos-1]=ele;
• cout<<"Array after insertion:"<<endl;
• for(i=0;i<=n;i++)
• {
• cout<<a[i]<<" ";
• }
• }
• else
• cout<<"Invalid position"<<endl;
• getch();
• }
