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
*p     = 4
++*p   = 5
*p     = 5
++(*p) = 6
