Questions tagged [cstring]

Refers to 0-terminated strings as popularized by C, as well as the header-files `string.h` and `cstring`.

A C string is a sequence of non-zero bytes terminated by a NUL byte (0x00), usually used to store ASCII or UTF-8 text.

C strings are defined as char arrays in C and C++, where char is an 8-bit type. C strings can be referred to using a char pointer.

Extensions to the basic C string (e.g. to 16-bit wchar_t "wide strings") also exist in various programming environments.

In C++, the standard std::string class interoperates with C strings via the .c_str() method, though beware that std::strings can contain embedded 0-bytes.
