字符指针不分配存储区，字符常量存储于静态数据区

参考：链接

C++ 字符数组有存储区，其值为存储区首地址；字符指针不分配存储区吗，"abc" 以常量形式存于静态数据区，指针指向该区首地址。

#include <iostream>

using namespace std;

int main()
{
    char s1[] = "abc";
    char s2[] = "abc";

    const char s3[] = "abc";
    const char s4[] = "abc";

    const char *s5 = "abc";
    const char *s6 = "abc";

    char *s7 = "abc";
    char *s8 = "abc";

    cout << boolalpha << (s1 == s2) << endl;
    cout << boolalpha << (s3 == s4) << endl;
    cout << boolalpha << (s5 == s6) << endl;
    cout << boolalpha << (s7 == s8) << endl;

    return 0;
}

Output：

false
false
true
true

进入int main()后：

完成赋值后：
