Why is it possible to assign a const char* to a char*?

Question

I know that for example \"hello\" is of type const char*. So my questions are:

1. How can we assign a literal string like \"hel

Answer 1

In your example, you are not assigning, but constructing. std::string, for example, does have a std::string(const char *) constructor (actually it's more complicated, but it doesn't matter). And, similarly, char * (if it was a type rather than a pointer to a type) could have a const char * constructor, which is copying the memory.

I don't actually know how the compiler really works here, but I think it could be similar to what I've described above: a copy of "Hello" is constructed in stack and s is initialized with this copy's address.
