Compilation error:a function -definition is not allowed here before '{token

[markcleo]

can anyone know whats the problem on it it says that my int getfingerprintidez a function-definition is not allowed here before

heres my sample code

After you've made 18 postings you still do not know how to post code in code tags?

Help us help you.

Please follow the advice given in this link How to get the best out of this forum when posting code, in particular the section entitled 'Posting code and common code problems'.

Things that suck:

a). Images of code suck.
b). Images of error messages suck.
c). Code snippets suck.

Use code tags (the </> icon above the compose window) to make it easier to read and copy code for examination

Use the IDE autoformat tool (ctrl-t or Tools, Auto format) before posting code in code tags.

Include the entire error message. It is easy to do. There is a button (lower right of the IDE window) called "copy error message". Copy the error and paste into a post in code tags. Paraphrasing the error message leaves out important information.

Post a schematic.

Post an image of your project.

Which Micro Controller are you using?

Is this simulator code?

Please describe the problem better then you just did.

Hi @markcleo

Kindly read the forum guidelines first and then edit your post accordingly

[bluejets]

If you expect any constructive reply, read the requirements for posting both code and error messages.

i already edit it sir thank u for your cooperation and information i just forgot it
