? 比较字符数组名比较的是内存地址 比较字符串名比较的是指向的内存里的内容

代码

int _tmain(int argc, _TCHAR* argv[]) { char str1[] = "abc"; char str2[] = "abc"; const char str3[] = "abc"; const char str4[] = "abc"; const char *str5 = "abc"; const char *str6 = "abc"; char *str7 = "abc"; char *str8 = "abc"; cout << &str1 << endl; cout << &str2 << endl; cout << &str3 << endl; cout << &str4 << endl; cout << &str5 << endl; cout << &str6 << endl; cout << &str7 << endl; cout << &str8 << endl; cout << (str1 == str2) << endl; cout << (str3 == str4) << endl; cout << (str5 == str6) << endl; cout << (str7 == str8) << endl; return 0; }

 

输出

002BFEAC 002BFEA0 002BFE94 002BFE88 002BFE7C 002BFE70 002BFE64 002BFE58 0 0 1 1 Press any key to continue . . .
