<p>空终止字节字符串（ null-terminated byte string, NTBS ）是后随拥有零值的字节（空终止字符）的非零字节序列。字节字符串的每个字节编码某字符集的一个字符。例如，字符数组 <span class="t-c"><span class="mw-geshi cpp source-cpp"><span class="br0">{</span><span class="st0">'<span class="es2">\x63</span>'</span>, <span class="st0">'<span class="es2">\x61</span>'</span>, <span class="st0">'<span class="es2">\x74</span>'</span>, <span class="st0">'<span class="es5">\0</span>'</span><span class="br0">}</span></span></span> 是持有以 ASCII 编码的字符串 <span class="t-c"><span class="mw-geshi cpp source-cpp"><span class="st0">"cat"</span></span></span> 的 NTBS 。</p>
