Are you sure about that?

Check that each { has a matching }

Please remember to use code tags when posting code.

kdhanesh327 · May 25, 2022, 3:45pm

please help me in this if you get this

anon73444976 · May 25, 2022, 3:46pm

Where did you get the code?

kdhanesh327 · May 25, 2022, 3:47pm

i resolved
lcd.noBacklight};

kdhanesh327 · May 25, 2022, 3:48pm

my error is shown in the "while (getID())"

anon73444976 · May 25, 2022, 3:52pm

Did you match the { with the } ?

Please post the actual error message, and try using the IDE's auto format tool on your code.

Where did you get the code?

wait i will upload the code file

this is the original code. i modify this code as per the need of our project

anon73444976 · May 25, 2022, 4:00pm

Go easy - you'll get a forum timeout if you keep posting too much.

Please go back to your last post and edit-in the code tags.

kdhanesh327 · May 25, 2022, 4:03pm

i didn't get u, what you are saying about

kdhanesh327 · May 25, 2022, 4:04pm

if i tell my project idea, could you help with my code?

anon73444976 · May 25, 2022, 4:06pm

I'm just going out for the evening, but I'm sure someone else will be along soon.

The compiler is correct, getID is not declared in your program.
