Problems with global variables
显示 更早的评论
I'm willing to use the global function to define some constant parameters in a structure. The written codes are as following
But according to the error reminder the current use of 'Biofilm' is inconsistent with the previous use or Definition. I couldn't understand this hint and still couldn't find the error. Could anyone help me with that? Thanks a lot!

As a rule, don't use global variables.
Why does Biofilm need to be global? It is already defined as a normal variable since it is an output of the function. It looks like you either don't understand what global variables are, or how functions work.

Regardless of his level of understanding, people come here to ask questions. Not to be ridiculed.

@Jacob, I'm not sure who your comment is addressed to. Nobody was being ridiculed in my post. There was a piece of advice and a genuine question that would have helped answering the OP question, had that question been answered.

You may have to remove Biofilm as the return argument, to make the function signature look like:
function setGlobalbiofilm()
As Biofilm is a global variable , it does not seem to be possible to declare it as a return value of a function. You can take a look at this documentation for further information.
