Insert an element in an array after a specific position.

Write a C++ program to Insert an element in an array after a specific position.

Program Code:

#include<iostream>

using namespace std;

int main()

{

int i, n, no,pos;

int array[100];

cout<<"Enter elements into the Array : ";

cin>>n;

for(i=0;i<n;i++)

{

cin>>array[i];

}

cout<<endl;

cout<<"Entered element into the Array are : ";

for(i=0;i<n;i++)

{

cout<<array[i];

cout<<" ";

}

cout<<endl;

cout<<"Enter position to insert new element into the Array: ";

cin>>pos;

cout<<endl;

if(pos>10)

{

cout<<"This is out of range";

}

else

{

cout<<"Enter new element to be inserted: ";

cin>>no;

cout<<endl;

for(i=n;i>=pos;i--)

{

array[i+1]=array[i];

}

array[pos]=no;
cout<<"After inserting new elements into the Array are : ";

for(i=0;i<n+1;i++)

{

cout<<array[i];

}

}

return 0;

}

The program output is tested on www.jdoodle.com

Output:

Enter elements into the Array : 1 2 3 4 5 6 7 8 9 10

Entered element into the Array are : 1 2 3 4 5 6 7 8 9 10

Enter position to insert new element into the Array: 9

Enter new element to be inserted: 30

After inserting new elements into the Array are : 1 2 3 4 5 6 7 8 9 30 10
