C ++：如何将对象数组传递给函数？

Question

I have a pointer to array of objects. It looks like:

MyClass *myClass[ 10 ];
myClass[ 0 ] = new MyClass(); // init for each of myClass[0..9]
myClass[ 0 ]->field1 = "hello";

How can I pass "myClass" to a function by reference? I tried a few cases but it didn't work.

If you really must use an array, then

template<size_t N >
void foo(MyClass (&arr)[N] )
{
  // Access arr[i], size is N
}

...

foo(myClass);

Otherwise, use an std::array

template<size_t N >
void foo(std::array<MyClass,N>& arr )
{
  // Access arr[i], size is N or arr.size()
} 

...

std::array<MyClass, 10> myClass = ....;
foo(myClass);

I would not call an array "myClass" though.
