#include <iostream>
using namespace std;


int a,arr[20],n,e;
void Delete()
{
    int n;
    cout<<"\nEnter element to delete:\n";
    cin>>n;
    for(int i=0;i<n;i++)
    {
    if(arr[i]==n)
    {
    arr[i]=0;
    cout<<n<<" deleted";
    }
    }
}
void create()
{
    cout<<"\n Enter the number of elements to create: "; cin>>n;
    cout<<"\nEnter the elements\n";
    for(int i=0;i<n;i++)
    {
        cin>>arr[i];
    }
}


void display(){
    for(int i=0;i<n;i++)
    {
    cout<<"\n"<<arr[i];
    }
}
void insert()
{
    int n;
    cout<<"\nEnter number of elements to insert: ";
    cin>>n;
    cout<<"\nEnter the elements\n";
    for(int i=0;i<n;i++){
        cin>>arr[n++];
    }
}




int main()
{
    int c;
    cout<<"\n1. Create \n2. Delete \n3. Insert \n4. Display \n5. Exit";
    do
    {
    cout<<"\nEnter your choice:";
    cin>>c;
    switch(c)
    {
        case 1: 
            create(); 
            break;
        case 2: 
            Delete(); 
            break;
        case 3: 
            insert(); 
            break;
        case 4:

            exit(0); 
            break;
        default:

    }
    }
    while(c<=6);
    return 0;
