C++ 中基本数据类型的最大最小值

#include <limits>
#include <iostream>
using namespace std;

int main ()
{
cout << (std::numeric_limits<int>::max)() << endl;
cout << (std::numeric_limits<unsigned>::max)() << endl;
cout << (std::numeric_limits<long int>::max)() << endl;

cout << "-----------------------------" << endl;

cout << (std::numeric_limits<int>::min)() << endl;
cout << (std::numeric_limits<unsigned>::min)() << endl;
cout << (std::numeric_limits<long int>::min)() << endl;

cout << "-----------------------------" << endl;
cout << (std::numeric_limits<float>::max)() << endl;
cout << (std::numeric_limits<float>::min)() << endl;

return 0;
