字符串，字符数组

# include <iostream># include <stdlib.h># include <stdio.h># include <string.h>using namespace std;int main(void){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 == str2) << endl;cout << (str3 == str4) << endl;cout << (str5 == str6) << endl;cout << (str7 == str8) << endl;return 0;}

结果是：0 0 11

解答：str1,str2,str3,str4是数组变量，它们有各自的内存空间；

而str5,str6,str7,str8是指针，它们指向相同的常量区域。
