C++ * vs [] as a function parameter

Question

What is the difference between:

void foo(item* list)
{
    cout << list[xxx].string;
}

and

void this(item list[])
{
          


        

Answer 1

FYI:

void foo(int (&a)[5]) // only arrays of 5 int's are allowed
{
}

int main()
{
  int arr[5];
  foo(arr);   // OK

  int arr6[6];
  foo(arr6); // compile error
}

but foo(int* arr), foo(int arr[]) and foo(int arr[100]) are all equivalent
