Here in this video, parameters are passing like int * out, so how this is different from passing the parameter by reference?

#1

this is a general question like what is the benefit of passing like int * x ? or when we should pass like int &x

#2

In C++ arrays are passed by reference by default so you can pass the address of array as a pointer instead. It is a very common way of passing arrays as parameters.
Method 1: func(int arr[])
Method 2: func(int *arr)
