C++ keyword: short - cppreference.com (original) (raw)

[edit] Usage

• short type modifier

[edit] Example

#include #include #include #include   static_assert(sizeof(short) >= 16 / CHAR_BIT); static_assert(sizeof(unsigned short) >= 16 / CHAR_BIT); static_assert(std::numeric_limits::min() <= -32'768); //' static_assert(std::numeric_limits::max() >= 32'767); //' static_assert(std::numeric_limits::max() >= 65'535u); //'   // concepts are available since C++20 static_assert(std::integral and std::integral);   template <typename T, typename... Ts> concept all_same = (... and std::same_as <T, Ts>);   static_assert(all_same<short, short int, signed short, signed short int>); static_assert(all_same<unsigned short, unsigned short int>);   #define OUT(...) std::cout << #__VA_ARGS__ << " = " << __VA_ARGS__ << '\n'   int main() { OUT(sizeof(short)); OUT(sizeof(unsigned short)); OUT(std::numeric_limits::min()); OUT(std::numeric_limits::max()); OUT(std::numeric_limits::max()); }   #undef OUT

Possible output:

sizeof(short) = 2 sizeof(unsigned short) = 2 std::numeric_limits::min() = -32768 std::numeric_limits::max() = 32767 std::numeric_limits::max() = 65535
