c++ - 取值范围(最小值和最大值)

Question

任何定义类型的最大值和最小值到底是多少？这可能吗？

unsigned int maximum_uint = (maximum_value)(unsigned int);
short minimum_short = (minimum_value)(short);
float maximum_float = (maximum_value)(float);

Answer 1

#include <limits>

unsigned int maximum_uint = std::numeric_limits<unsigned int>::max();
short minimum_short = std::numeric_limits<short>::min();
float maximum_float = std::numeric_limits<float>::max();
