Console writeline

Question

In this example :

 

Console.writeline("AAAAAAAAAAAAABBBBBBBBBBBBBBBBBBCCCCCCCCCCC");

 

if all the letters are in one line i am not getting any error . But, if i do like this i am getting error. Why? 

 

Console.writeline("AAAAAAAAAAAAABBBBBBBBBBBBBBBBBB 

                            CCCCCCCCCCC");

 

 

How to get rid of this problem?
