Welcome to the forum

It helps if you post the full error message that you got. As it happens I can guess that it said that a primary expression was expected before the closing brace of the setup() function

A primary expression is a complete code statement

Look closely at this line of code

lcd.print("12345")

Is something missing from it ?

thats not the problem

So, your in-depth explanation of the problem wasn’t enough for us.

the error code i got is expected primary-expression before '.' token

It will be if you don't fix it

How about this line

    lcd.setCursor(, 0);

Shouldn't there be something before the comma ?

Or this line

    lcd.begin;

Shouldn't there be some brackets after the function name, maybe even some parameters ?

Please post the full error message as requested

You are wrong. This is also a problem, the compiler just hasn't figured it out yet. When you fix the first error, it will highlight that line for you later.

The real problem is that you don't have the most basic understanding of programming language syntax - for example, that there is a semicolon after each line.
I would recommend you to read any basic book on the language before moving on.
