Yes. If an array is declared such as:

new myArray[54]

then

new Size_of_myArray = sizeof(myArray)

will be compiled as if the code is:

new Size_of_myArray = 54

So, if the dimension is not defined, it shouldn't work.

but is it really a pre-processor function?

Using -l argument in the compiler "-l create list file (preprocess only)"

using charsmax shows

new Size_of_myArray = (sizeof(myArray)-1)

using sizeof shows

new Size_of_myArray = sizeof(myArray)

So is it replaced at the compilation or not?

creating something like that

#define size 30

will be replaced like that :

new Size_of_myArray = 30

If you have further questions about the Pawn language, I recommend that you consult the Pawn Language Guide.

Thanks but I searched yesterday on the new guide package didn't find anything intresting related to sizeof.

I just need to understand something, if it's a pre-processor directive then why it is not resolved during the first stage which is "preprocessing"? ( You can check that using "-l" argument in the compiler "amxxpc.exe" )

So the value evaluates at compile time means that sizeof isn't a pre-processor directive.

btw it's an operator not a function.

If it's not a pre-processor directive then a very knowledgeable member of this community has misinformed people.

The only way to be really sure is to decompile a plugin and see what actually happens during compilation. I would do this but for some reason, the disassembler that I have does not seem to be working.

Anyways, this is way off-topic. Any further discussion about this should happen elsewhere in its own thread.
