在哪里放置编译时常量数组？
假设我有一个存储前10个素数的数组，如下所示：
const int primes[] = {2, 3, 5, 7, 11, 13, 17, 19, 23, 29};
// primes.h:
extern const int primes[10];
// primes.cpp:
extern const int primes[] = {2, 3, 5, 7, 11, 13, 17, 19, 23, 29};
inline int prime(int i) {
static const int primes[] = {2, 3, 5, 7, 11, 13, 17, 19, 23, 29};
return primes[i];
}
没有找到相关结果

template <bool dummy> struct primes_lut { static const int values[]; }; template<bool dummy> const int primes_lut<dummy>::values[] = { 2, 3, 5, 7, 11, 13, 17, 19, 23, 29 }; static auto& primes = primes_lut<true>::values;struct primes_lut { int values[10]; }; inline const primes_lut& primes_lut_provider(void) { static const primes_lut values = { {2, 3, 5, 7, 11, 13, 17, 19, 23, 29} }; return values; } static const int (&primes)[10] = primes_lut_provider().values;闪脖
芭隘的盘石
static const int primes[] = {2, 3, 5, 7, 11, 13, 17, 19, 23, 29};
