Hey all, I am trying to get a full understanding of mutable/immutable string syntax. I understand it to be true that 'char[]' is mutable and that 'string' is immutable and is the same as invariant(char)[]. If I am incorrect on any of this, please let me know.
The page: http://www.digitalmars.com/d/2.0/arrays.html gives the following example as an initialization error: char[] str1 = "abc"; // error, "abc" is not mutable I assume this is an error because of incompatible types (trying to set a mutable type to an immutable value. However, and this confuses me. The page: http://www.digitalmars.com/d/2.0/cppstrings.html char[] s1 = "hello world"; char[] s2 = "goodbye ".dup; s2[8..13] = s1[6..11]; // s2 is "goodbye world" If what I have assumed is true so far, why is the following line from above allowed?: char[] s1 = "hello world"; On a slightly different note, why does the compiler allow me to set an immutable value to a mutable type if it is an error? I am using dmd v1.033 -- Is this for v2.xx only? Thanks for any information that you can provide and sorry if these questions have already been answered. Thanks, Zane
