Terminazione Null stringa di byte (NTB) è una sequenza di byte diversi da zero seguito da un byte con valore pari a zero (il carattere nullo di terminazione). Ogni byte in una stringa di byte codifica un carattere di alcuni set di caratteri. Ad esempio, il {'\x63','\x61','\x74','\0' array di caratteri} è un NTB che fissano la "cat" stringa in codifica ASCII.

Original:

A null-terminated byte string (NTBS) is a sequence of nonzero bytes followed by a byte with value zero (the terminating null character). Each byte in a byte string encodes one character of some character set. For example, the character array {'\x63','\x61','\x74','\0'} is an NTBS holding the string "cat" in ASCII encoding.
