C表初始化

Question

I want to intialise a table that should contain a few chars for comparing it to values later, this is my code:

 char z[8] = {' ', '.', '\', ':', 'o', '&', '8', '#', '@'};

I get a bunch of error messages from the compiler though, some are:

dn08.c: In function ‘main’:

Answer 1

You can try escaping the backslash

 char z[] = {' ', '.', '\\', ':', 'o', '&', '8', '#', '@'};

These two backslashes at z[2] will be treated as one backslash while only one backslash in your code messes everything up.

You also don't really need to specify the array length as it'll be auto-calculated for you by the compiler.
