Difference between Text And Binary

[fsn]

Dear All,

I would appreciate some help regarding what is the difference between Binary and Text. For example:

char s[6] = "bytes";

s is a bunch of bytes that you tell the compiler to treat them as an array of chars.
1) How do you convert this to an array of bytes using C? (binary mode)
2) If you explore a string with an Hex Editor, what are the differences in memory if you have this string in a text mode or if you have it in a binary mode?

Thank you.
