C++输出指针自增(++)运算示例

#include "stdafx.h"
#include <iostream>

using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
	char s[] = "012345678", *p = s;
	
	cout << "s:"<<s<<endl;
	cout << "*p++ = " << *p++ << ", *(p++) = " << *(p++) << ", (*p)++ = " << (*p)++ << ", *++p = " << *++p << ", *(++p) = "<< *(++p) << ", ++*p = " << ++*p << ", ++(*p) = "<< ++(*p) << endl;
	cout<<"-------------------"<<endl;
	
	char s1[] = "012345678";
	p = s1;
	cout << endl << "s1:"<<s1<<endl;
	cout << "*p     = " << *p <<endl;
	cout << "*p++   = " << *p++ << endl;
	cout << "*p     = " << *p <<endl;
	cout << "*(p++) = " << *(p++) << endl;
	cout << "*p     = " << *p <<endl;
	cout << "(*p)++ = " << (*p)++ << endl;
	cout << "*p     = " << *p <<endl;
	cout << "*++p   = " << *++p << endl;
	cout << "*p     = " << *p <<endl;
	cout << "*(++p) = " << *(++p) <<endl;
	cout << "*p     = " << *p <<endl;
	cout << "++*p   = " << ++*p << endl;
	cout << "*p     = " << *p <<endl;
	cout << "++(*p) = " << ++(*p) <<endl;
	cout<<"-------------------"<<endl;

	system("pause");
	return 0;
}

输出：

s:012345678
*p++ = 3, *(p++) = 3, (*p)++ = 2, *++p = 4, *(++p) = 4, ++*p = 4, ++(*p) = 4
-------------------

s1:012345678
*p = 0
*p++ = 0
*p = 1
*(p++) = 1
*p = 2
(*p)++ = 2
*p = 3
*++p = 3
*p = 3
*(++p) = 4
