c++ - Using NULL as a terminator in arrays? -


i "reinventing wheel" learning purposes, i'm working on container class strings. using null character array terminator (i.e., last value in array null) cause interference null-terminated strings?

i think issue if empty string added, might missing something.

edit: in c++.

"" empty string in c , c++, not null. note "" has 1 element (instead of zero), meaning equivalent {'\0'} array of char.

char const *notastring = null; char const *emptystring = "";  emptystring[0] == '\0';  // true notastring[0] == '\0';   // crashes
