Is a string literal in c++ created in static memory?
C++ string literal data type storage
In this code:
const char * str = "hello world";
If I understand correctly a pointer is 4 or 8 bytes, which I guess would be allocated on the stack.
But where is the memory for the “hello world” allocated and stored?
Or what does str point to exactly?
It’s not allocated. It’s generally stored in your program’s code segment or on the stack That’s up to the compiler. Either way, it points to a null-terminated array of characters.
