I am doing programs in The C Programming Language by Kernighan and Ritchie.
I am currently at exercise 1-24 that says:
Write a program to check a C Program for rudimentary syntax errors like unbalanced parentheses, brackets and braces. Don't forget about quotes, both single and double,
escape sequences, and comments.
I have done everything well... But I am not getting how escape sequences would affect these parentheses, brackets and braces?
Why did they warned about escape sequences?
In "\"", there are three double quote characters, but still it's a valid string literal. The middle " is escaped, meaning the outer two balance each other. Similarly, '\'' is a valid character literal.
Parentheses, brackets and braces are not affected, unless of course they appear in a string literal that you don't parse correctly because of an escaped quote.
