Compare Two Array and save it to Another Array By save the small array in 1st in C++.

#include <iostream>

using namespace std;

int main()

{

    int array1[100],array2[100],i,n,m,count=0,j;

    int n_array[200];

    cout<<"Please Enter 1st Array Size: "<<endl;

    cin>>n;

    cout<<"Please Enter Array Element: ";

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

    {

        cin>>array1[i];

    }

    cout<<"Please Enter 2nd Array Size: "<<endl;

    cin>>m;

    cout<<"Please Enter Array Element: ";

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

    {

        cin>>array2[i];

    }

    if(n>m) ///check which array is bigger
