My issue

My code

#include <iostream>
using namespace std;

int main() {
	// your code goes here
	int t,a,n;
	cin>>t;
	for(int i=1;i<t+1;i++){
	    cin>>n>>a;
	    int arr[n];
	    int arr1[n];
	    int count=0;
	    for(int j=0;j<n;j++){
	        cin>>arr[j];
	    }
	    for(int j=0;j<n;j++){
	        arr1[j]=arr[j]+10;
	    }
	    for(int j=0;j<n;j++){
	        if((arr1[j]%7)==0){
	            count++;
	        }
	    }
	    cout<<count<<endl;
	}
	return 0;

@goyalsajal92
its should be arr1[j]=arr[j]+a;
