Re: [Boost-users] compile-time string literal manipulation?

2010/10/28, Stiles Watson :

Question. For the example given at the link above, it has

typedef mpl::string<'hell','o wo','rld'> hello;

Why would it not be

typedef mpl::string<'h','e','l','l','o',' ','w','o','r','l','d'> hello;

OR if the example is correct, why could you not simply do

typedef mpl::string<'hello world'> hello;

Note that they are multi-character character constants (in single quote), not strings (in quotes), and multi-character character may have at most the size of int, so you cannot have a single 'hello world'.
