10^9以下用int
,10^18以下用long long
。
C++代码如下
#include<iostream>
#include<string>
#include <limits>
using namespace std;
int main()
{
cout << "type: " << "************size**************" << endl;
cout << "bool: " << "numOfBytes:" << sizeof(bool);
cout << " maxValue:" << (numeric_limits<bool>::max)();
cout << " minValue:" << (numeric_limits<bool>::min)() << endl;
cout << "char: " << "numOfBytes:" << sizeof(char);
cout << " maxValue:" << (numeric_limits<char>::max)();
cout << " minValue:" << (numeric_limits<char>::min)() << endl;
cout << "signed char: " << "numOfBytes:" << sizeof(signed char);
cout << " maxValue:" << (numeric_limits<signed char>::max)();
cout << " minValue:" << (numeric_limits<signed char>::min)() << endl;
cout << "unsigned char: " << "numOfBytes:" << sizeof(unsigned char);
cout << " maxValue:" << (numeric_limits<unsigned char>::max)();
cout << " minValue:" << (numeric_limits<unsigned char>::min)() << endl;
cout << "wchar_t: " << "numOfBytes:" << sizeof(wchar_t);
cout << " maxValue:" << (numeric_limits<wchar_t>::max)();
cout << " minValue:" << (numeric_limits<wchar_t>::min)() << endl;
