 # Strings
 
-In V one can define strings using the `:=` operator. Strings (like other variables) are immutable by default. One is free to use `""` or `''` to denote a string. When using `vfmt` all double-quoted strings will be converted to single-quoted ones unless it contains a single quote character.
+In V one can define strings using the `:=` operator. Strings (like other variables) are immutable by default i.e you cannot change its value. String are also null (`\0`) terminated for easy C interpolation. One is free to use `""` or `''` to denote a string. When using `vfmt` all double-quoted strings will be converted to single-quoted ones unless it contains a single quote character.

+String can also be multi-lined:

 Getting the length of a string works with `.len`.

+You can also define C-strings with `c` as prefix for C interpolation. They are null terminated by default.

+**NOTE**: raw and c strings are not usuable with character literals.

+If you want to change the contents of the string then you can do so in `unsafe` expression:

+println(name) // Bob
+unsafe {

+    name[2] = `g`
