 Example 2: Multiply an array by a constant
• The macro takes two arguments:
• Array of any size
• Constant
• It returns an array equal to array * constant
• Plan of calculation:
• Create an array to hold the answer
• Iterate through the argument array:
• Pick up the array element
• Multiply it by the constant
• Insert the result into the corresponding place in the answer array
• This one is trickier because we don’t know the size of the array
• This is really useless, because Excel can do this without a macro

In our next example, we multiply an array by a constant, which Excel already can do. In our previous example, we knew that the arrays were 3x3. The twist here is that we won’t assume, as we write the code, that we know how big the array is.

This will require us to compute the size of the answer array and declare it “on the fly.”
