constant keyword question

[technologist]

I was recently reading about manipulating strings, and it was highly recommended to use the constant keyword with c-style strings...what I want to know is not so much what const does(although that would be ok) but more what will happen if I don't use const..

Use the constant keyword with string literals

The code will not compile (with a conforming compiler).
