Hi there, I got two questions regarding lookup tables: 1. How do you fill one in a neat way if the contents don''t match any pattern ? ( Example: IndexTable[2][2][16] ) If it''s a part of a class and let''s say all the instances wanna use this table... 2. What is a good approach to initialize it ? So far my ideas were the following: 1. The array is ''static'' in the class 2. A static function like InitTable()that is called before the first instance. 3. Like 2. but the function is called in the constructor with a static flag to prevent further initialization. Somehow I don''t like those. Is there a better way ? Any comment appreciated. Lorenz

int a[3][2] = {{1,2},{3,4},{5,6}};

If all instances wanna share it, you can do it with statics..

  
struct B {
static const A a[2];
};

const A B::a[2] = { A(1), A(2) };

Or maybe have InitTable() that eg. loads it from a file. Whatever you prefer.
