Great video on Static Arrays! I always struggled with understanding how to use them effectively in VBA. Could you explain a bit more about the difference between Static and Dynamic Arrays?
Thank you for your comment! I'm glad you found the video helpful. Static Arrays have a fixed size defined at the time of declaration, which means you can't change their size during runtime. On the other hand, Dynamic Arrays can be resized as needed using the ReDim statement. This flexibility makes Dynamic Arrays more suitable for situations where the number of elements can change. I'll cover Dynamic Arrays in detail in an upcoming video, so stay tuned!
Nice video, very useful for practice array concepts,i have question that Can we declare array as static? And Are arrays always static?
Thank you! I'm glad you found the video useful for practicing array concepts. Yes, you can declare an array as static in VBA by specifying its size at the time of declaration, which makes it fixed in size. For example:
Dim arr(10) As Integer
However, arrays in VBA are not always static. You can also declare dynamic arrays, which can be resized during runtime using the ReDim statement. For example:
Dim dynArr() As Integer
ReDim dynArr(10)
This allows you to adjust the size of the array as needed. We'll cover dynamic arrays in more detail in an upcoming video. Stay tuned!
How can I initialize a static array with default values when declaring it?
Great question! In VBA, when you declare a static array, it is automatically initialized with default values (e.g., 0 for numeric types, empty string for strings). However, if you want to initialize it with specific values, you'll need to assign them manually after declaration:
Dim arr(3) As Integer
arr(0) = 1
arr(1) = 2
arr(2) = 3
arr(3) = 4
There isn't a direct way to initialize with specific values at the point of declaration
