WebFeb 7, 2024 · Abstract. Dynamic arrays are very useful data structures. They can be initialized with variable size at runtime. This size can be modified later in the program to expand (or) shrink the array. Unlike fixed-size arrays and Variable Length Arrays, Dynamically sized arrays are allocated in a heap. Flexible Array Members closely … WebWe declare a dynamic array using the Dim statement and we set the size later using ReDim. ' DYNAMIC ARRAY ' Declare the variable Dim arrLong() As Long ' Set the size ReDim arrLong(0 To 6) As Long . Using ReDim. The big difference between Dim and ReDim is that we can use a variable in the ReDim statement. In the Dim statement, the size …
