Why this shows code show did you account for negative values?

#1

int main()
{
int n1,n2,num=0;
int temp =0;
cin>>n1>>n2;
while(n1>0)
{
num = n1%10;
n1=n1/10;
if(n2&num == n2)
{
temp++;
}
}
cout<<temp<<endl;
return 0;
}

hi @deepshreyamishra301_1918130c8477386b,
write if(num == n2) instead of if(n2&num == n2) (you just need to check if that digit is equal to n2)
