Usage

• short type modifier

Example

Run this code

#include <climits>
#include <concepts>
#include <iostream>
#include <limits>
 
static_assert(sizeof(short) >= 16 / CHAR_BIT);
static_assert(sizeof(unsigned short) >= 16 / CHAR_BIT);
static_assert(std::numeric_limits<short>::min() <= -32'768); //'
static_assert(std::numeric_limits<short>::max() >= 32'767); //'
static_assert(std::numeric_limits<unsigned short>::max() >= 65'535u); //'
 
// concepts are available since C++20
static_assert(std::integral<short> and std::integral<unsigned short>);
 
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<short>::min());
    OUT(std::numeric_limits<short>::max());
    OUT(std::numeric_limits<unsigned short>::max());
}
 
#undef OUT

Possible output:

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