Possible Duplicate: Programmatically create static arrays at compile time in C++ I have lots of data to be stored in a fixed array, with its elements depend on position. The value of each element ...

Possible Duplicate: Programmatically create static arrays at compile time in C++ Is it possible to initialize the following array in compile time? template<int n> void foo() { static ...

C++ Notes: Array Initialization has a nice list over initialization of arrays. I have a int array[100] = {-1}; expecting it to be full with -1's but its not, only first value is and the rest are 0's ...

I want to do something like this: template<int N> char* foo() { // return a compile-time string containing N, equivalent to doing // ostringstream ostr; // ostr << N; // return ...

Suppose I have some constexpr function f: constexpr int f(int x) { ... } And I have some const int N known at compile time: Either #define N ...; or const int N = ...; as needed by your answer. I ...

Suppose I have a class X, which functionality requires a lot of constant table values, say an array A[1024]. I have a recurrent function f that computes its values, smth like A[x] = f(A[x - 1]); ...

There was an answer on stackoverflow (which I can't seem to find anymore) which demonstrated how a variadic template can be used in C++11 to create a static array at compile time: template <class ...

I have found two good approaches to initialise integral arrays at compile times here and here. Unfortunately, neither can be converted to initialise a float array straightforward; I find that I am ...

I have a global array, which is indexed by the values of an enum, which has an element representing number of values. The array must be initialized by a special value, which unfortunately is not a 0. ...

I have the following template class: template <unsigned N> class XArray { static const int Xdata[N]; }; I want to initialize the static const array for each XArray<N> I used, for ...

I'm currently working on a template-meta-programming based implementation of floating-point arithmetic. The template which represent compile-time float values is as follows: template<bool S , std::...

I wonder if it is possible to initialize an entire array with a constexpr function (with C++ 2011). Here I have something to illustrate what I want to do : template<unsigned int DIM> const ...

Is it possible to generate an array at compile time, like in this nice answer of G. Fritzsche: Georg Fritzsche but with floating point values? I think its not possible in this manner because, the ...

I was wondering if its possible to make the following answer more generic, in the sense that the type of the array be templated instead of just unsigned: I've enclosed the whole thing in a struct ...

Let's say that I need to create a LUT containing precomputed bit count values (count of 1 bits in a number) for 0...255 values: int CB_LUT[256] = {0, 1, 1, 2, ... 7, 8}; If I don't want to use hard-...
