一、类型含意

bool:                     b

char:                     c
signed char:              a
unsigned char:            h

(signed) short (int):     s
unsigned short (int):     t

(signed) (int):           i
unsigned (int):           j

(signed) long (int):      l
unsigned long (int):      m

(signed) long long (int): x
unsigned long long (int): y

float:                    f
double:                   d
long double:              e

二、实验

#include <iostream>

#include <typeinfo>

using namespace std;
int main()
{
		bool a1;char a2;signed char a3;unsigned char a4;
		
		short a5;unsigned short a6;
		
		int a7;unsigned int a8;

		long  a9;unsigned long a10;long long a11;unsigned long long a12;

		float a13;
		double a14;
		long double a15;
		
		cout<<typeid(a1).name()<<"表示:bool"<<endl;
		cout<<typeid(a2).name()<<"表示:char"<<endl;
		cout<<typeid(a3).name()<<"表示:signed char"<<endl;
		cout<<typeid(a4).name()<<"表示:unsigned char"<<endl;
		cout<<typeid(a5).name()<<"表示:short"<<endl;
		cout<<typeid(a6).name()<<"表示:unsigned short"<<endl;
		cout<<typeid(a7).name()<<"表示:int"<<endl;
		cout<<typeid(a8).name()<<"表示:unsigned int"<<endl;
	
		cout<<typeid(a9).name()<<"表示:long"<<endl;
		cout<<typeid(a10).name()<<"表示:unsigned long"<<endl;
		cout<<typeid(a11).name()<<"表示:long long"<<endl;
		cout<<typeid(a12).name()<<"表示:unsigned long long"<<endl;
		cout<<typeid(a13).name()<<"表示:float"<<endl;
		cout<<typeid(a14).name()<<"表示:double"<<endl;
		cout<<typeid(a15).name()<<"表示:long double"<<endl;
	
		int* aa;
		cout<<typeid(aa).name()<<"表示:int指针类型"<<endl;
		cout<<typeid(*aa).name()<<"表示:int"<<endl;
	
		char** bb;
		cout<<typeid(bb).name()<<"表示:"<<endl;
		cout<<typeid(*bb).name()<<"表示:char指针类型"<<endl;
		cout<<typeid(**bb).name()<<"表示:char"<<endl;
		
		char* cc=new char;
		cout<<typeid(cc).name()<<"表示:char指针类型"<<endl;
		cout<<typeid(*cc).name()<<"表示:char"<<endl;
	
		string* dd=new string("abc");
		cout<<typeid(dd).name()<<"表示:string指针类型"<<endl;
		cout<<typeid(*dd).name()<<"表示:string"<<endl;
	
		char* ee=new char[3]{'a','b','c'};
		cout<<ee<<endl;
		cout<<&ee<<endl;
		cout<<ee[0]<<endl;
		cout<<&ee<<endl;
		cout<<&ee[2]<<endl;
		cout<<"字符串1"<<endl;
		string *ss=new string[2]();
		cout<<ss<<endl;
		cout<<&ss<<endl;
	
		cout<<"字符串2"<<endl;
		string *sss=new string[2]{"nihao","abc"};
		cout<<sss<<endl;
		cout<<*sss<<endl;
		cout<<*(sss+1)<<endl;
		cout<<&sss<<endl;

}
