Variable storage location

Question

When we declare a variable as

char arr[] = "Hello";

then the string "Hello" above is located in stack.

But when we declare a variable as

char* arr = "Hello";

then the string "Hello" is declared in stack or code segment? If code segment then why code segment and not in stack?

There are four storage duration models in C++. None of them mentions stack nor code segment. Your second statement is not portable C++. — Ron, Jul 25 '18 at 10:44
"`char* arr = "Hello";`" should be `const char* arr = "Hello";` — Jesper Juhl, Jul 25 '18 at 10:54

No. The string literal is not declared in any segment.

It's got static storage duration and it's read-only.

Because it's read-only, assigning its address to a char* is incorrect. Change it to char const* arr = "...";
