How do you pass an array in VBA?
Arrays can be passed to proceedures by putting () after the name of the array variable. Arrays must be passed by reference. If no passing mechanism is specified, e.g. myFunction(arr()) , then VBA will assume ByRef by default, however it is good coding practice to make it explicit.
Can you pass an array through a function VBA?
It is possible to pass an array into a subroutine or function. Arrays are always passed in by reference (ByRef). This means that any changes to the array will be passed back to the calling routine. You can pass both dynamic and fixed arrays to subroutines and functions.
How do you pass a two dimensional array to a function in C++?

How do I get the size of an array in C++?
How to find the length of an array in C++

- using namespace std;
-
- int main() {
- int arr[] = {10,20,30,40,50,60};
- int arrSize = sizeof(arr)/sizeof(arr[0]);
- cout << “The size of the array is: ” << arrSize;
- return 0;
Why array of reference is not possible?
An array of references is illegal because a reference is not an object. According to the C++ standard, an object is a region of storage, and it is not specified if a reference needs storage (Standard §11.3. 2/4). Thus, sizeof does not return the size of a reference, but the size of the referred object.
What is ParamArray in VBA?
ParamArray allows you to pass an arbitrary number of arguments to the procedure. A ParamArray parameter is always declared using ByVal.

How do you pass an array by reference in C?
The C language does not support pass by reference of any type. The closest equivalent is to pass a pointer to the type. also be aware that if you are creating a array within a method, you cannot return it.
Why declare a pointer to an array of different sizes?
The neat thing about declaring a pointer like this is that you will get a compile time error if you try to assign a pointer of an array of different size to p. It will also give you a compile time error if you try to assign the value of a simple char pointer to p.
How do you modify the contents of an array in C?
In C arrays are passed as a pointer to the first element. They are the only element that is not really passed by value (the pointer is passed by value, but the array is not copied). That allows the called function to modify the contents.
