With a char* pointer in hand, one cannot really tell whether it is referring to an actual C string following the null-termination convention, or a char array full of characters interpreted as a "string", but without null termination, or a char array full of arbitrary byte values meaning anything. And from that source flow thousands upon thousands of C program bugs. :(

The distinction can conveniently be indicated in C++, as in the example at the bottom of [1]: "…" converts as a C string which truncates at the first \0, whereas "…"s converts to a std::string that keeps track of the full length.
