Pointer to const char vs char array vs std::string

Question

Here I\'ve two lines of code

const char * s1 = \"test\";
char s2 [] = \"test\";

Both lines of code have the same behavior, so I cannot see

Answer 1

const char * s1 = "test";
char s2 [] = "test";

These two aren't identical. s1 is immutable: it points to constant memory. Modifying string literals is undefined behaviour.

And yes, in C++ you should prefer std::string.
