error '{' and '}'

[kazal]

hi, i got error like this..

error: a function-definition is not allowed here before '{' token
error: expected '}' at end of input

what these two errors means?

They mean that you have a function definition where one is not permitted, i.e. exactly what the words say. This possibly arises because you are missing a closing brace or semicolon earlier in the file.
