eol while scanning string literal

This error occurs when there is an end-of-line character within a string literal, which is not valid syntax in most programming languages. To fix this error, you need to either remove the end-of-line character or escape it using the appropriate escape sequence depending on the language you are using.

For example, in Python, you can use the backslash (\) character to escape an end-of-line character within a string:

my_string = "This is a string \
             with an end-of-line character"

In JavaScript, you can use the backslash (\) character to escape an end-of-line character within a string:

var myString = "This is a string \
               with an end-of-line character";

Make sure to check the syntax rules of the programming language you are using to ensure that your code is valid.
