Compile-time assertion?

Question

Is there a way I can assert that two constant expressions are equal at compile time?

e.g. I want this to cause a compile-time error

enum { foo=263,          


        

Answer 1

you can define your own static assertion , this way :

#include 
template  class ClassStaticAssert;
template <>
class ClassStaticAssert{static const bool value = true;};
#define STATIC_ASSERT(e) (ClassStaticAssert())
int main()
{
    STATIC_ASSERT(0);
    return 0;
}
