Re: [boost] [random] example code fails inside struct

Why does the example code from the docs fail to compile when placed inside a struct or class? What am I missing?

You can't initialize a class data member like that. boost::uniform_int<> million(1,1000000); is valid in a function body or in namespace-scope, but not in class scope. In C++11 I think you could do this however: boost::uniform_int<> million{1,1000000};
