initialize a const array in a class initializer in C++

Question

I have the following class in C++:

class a {     const int b[2];     // other stuff follows      // and here's the constructor     a(void); } 

The question is, how do I initialize b in the initialization list, given that I can't initialize it inside the body of the function of the constructor, because b is const?

This doesn't work:

a::a(void) :      b([2,3]) {      // other initialization stuff } 

Edit: The case in point is when I can have different values for b for different instances, but the values are known to be constant for the lifetime of the instance.

With C++11 the answer to this question has now changed and you can in fact do:

struct a {     const int b[2];     // other bits follow      // and here's the constructor     a(); };  a::a() :     b{2,3} {      // other constructor work }  int main() {  a a; }
