c++ 类型int、long、double、char等的表示范围（最大最小值）

下面是一段测试代码

#include<iostream>  
#include<string>  
#include <limits>  
using namespace std;  
  
int main()  
{  
    cout << "type: 		" << "************size**************"<< endl;  
    cout << "bool: 		" << "所占字节数：" << sizeof(bool);  
    cout << "	最大值：" << (numeric_limits<bool>::max)();  
    cout << "		最小值：" << (numeric_limits<bool>::min)() << endl;  
    cout << "char: 		" << "所占字节数：" << sizeof(char);  
    cout << "	最大值：" << (numeric_limits<char>::max)();  
    cout << "		最小值：" << (numeric_limits<char>::min)() << endl;  
    cout << "signed char: 	" << "所占字节数：" << sizeof(signed char);  
    cout << "	最大值：" << (numeric_limits<signed char>::max)();  
    cout << "		最小值：" << (numeric_limits<signed char>::min)() << endl;  
    cout << "unsigned char: 	" << "所占字节数：" << sizeof(unsigned char);  
    cout << "	最大值：" << (numeric_limits<unsigned char>::max)();  
    cout << "		最小值：" << (numeric_limits<unsigned char>::min)() << endl;  
    cout << "wchar_t: 	" << "所占字节数：" << sizeof(wchar_t);  
    cout << "	最大值：" << (numeric_limits<wchar_t>::max)();  
    cout << "		最小值：" << (numeric_limits<wchar_t>::min)() << endl;

    cout << "		最小值：" << (numeric_limits<short>::min)() << endl;  
    cout << "int: 		" << "所占字节数：" << sizeof(int);  
    cout << "	最大值：" << (numeric_limits<int>::max)();  
    cout << "	最小值：" << (numeric_limits<int>::min)() << endl;  
    cout << "unsigned: 	" << "所占字节数：" << sizeof(unsigned);  
    cout << "	最大值：" << (numeric_limits<unsigned>::max)();  
    cout << "	最小值：" << (numeric_limits<unsigned>::min)() << endl;  
    cout << "long: 		" << "所占字节数：" << sizeof(long);  
    cout << "	最大值：" << (numeric_limits<long>::max)();  
    cout << "	最小值：" << (numeric_limits<long>::min)() << endl;  
    cout << "unsigned long: 	" << "所占字节数：" << sizeof(unsigned long);  
    cout << "	最大值：" << (numeric_limits<unsigned long>::max)();  
    cout << "	最小值：" << (numeric_limits<unsigned long>::min)() << endl;  
    cout << "double: 	" << "所占字节数：" << sizeof(double);  
    cout << "	最大值：" << (numeric_limits<double>::max)();  
    cout << "	最小值：" << (numeric_limits<double>::min)() << endl;  
    cout << "long double: 	" << "所占字节数：" << sizeof(long double);  
    cout << "	最大值：" << (numeric_limits<long double>::max)();  
    cout << "	最小值：" << (numeric_limits<long double>::min)() << endl;  
    cout << "float: 		" << "所占字节数：" << sizeof(float);  
    cout << "	最大值：" << (numeric_limits<float>::max)();  
    cout << "	最小值：" << (numeric_limits<float>::min)() << endl;  
    cout << "size_t: 	" << "所占字节数：" << sizeof(size_t);  
    cout << "	最大值：" << (numeric_limits<size_t>::max)();  
    cout << "	最小值：" << (numeric_limits<size_t>::min)() << endl;  
    cout << "string: 	" << "所占字节数：" << sizeof(string) << endl;  
    // << "	最大值：" << (numeric_limits<string>::max)() << "	最小值：" << (numeric_limits<string>::min)() << endl;  
    cout << "type: 		" << "************size**************"<< endl;  
    return 0;  
}  

这是vs2012 的输出

这是GCC version 5.1.0 (tdm-1)的输出
