What is the difference between strings and C strings?

C-strings are simply implemented as a char array which is terminated by a null character (aka 0 ). This last part of the definition is important: all C-strings are char arrays, but not all char arrays are c-strings. C-strings of this form are called “string literals“: … h and in the C++ header cstring .
