Also, both functions guarantee that the destination will be NUL-terminated as long as the size is at least one (you can't put anything into a zero-length buffer).
此外，只要目标的大小至少为1，两个函数都保证目标将以NUL结尾(您不能将任何内容放入零长度的缓冲区)。
This failure says that I haven't tested the code using a zero-length array. That's easy enough to fix, so I can just add a quick test and move on to the next failure, shown in Listing 4.
这个失败说，我没有用长度为零的数组测试该代码。

The zero-length rigid element is introduced to simulate the node at which more elements are jointed together and to treat neighboring elements whose longitudinal axes are not in the same line.
引入零长度刚性元模拟多个刚体元汇交于一点和相邻刚体元轴线不在一直线上等情形。
If the file begins with a delimiter, the node treats the (zero length) file contents preceding that delimiter as a record and propagates an empty record to the flow.

If the file ends with a delimiter the (zero length) file content following the final delimiter is still propagated although it contains no data.
如果文件以分隔符结尾，则仍然传播最后一个分隔符后面的(零长度)文件内容，尽管其中没有包含数据。

For instance, you can see that any time the if condition is true, the nested while loop will execute at least one time (because the list length will be greater than zero).
例如，您可以看到，每当if条件为真的时候，嵌入其中的while循环至少会执行一次(因为list的长度肯定大于0)。
A string whose length is greater than zero is always evaluated as True when resolved to a Boolean function, even if its value is the string 'false'.
长度大于0的字符串在解析为Boolean函数时，总是被判断为True，即使它的值是字符串'false '时亦是如此。
A quantum state is a vector whose overall length is of no interest to us (as long as it's not zero).
量子态是向量，我们并不关心其总长度(只要不是0)。
If the length of the original value is greater than zero and matches the index value, both are shown in green; otherwise the values are shown in red.
如果初始值的长度比0大且和索引值相匹配，这两者都会以绿色显示；否则显示红色。
zero() is slowest, because the JIT can't yet optimize away the cost of getting the array length once for every iteration through the loop.
zero()是当中最慢的，因为对于这个遍历中的历次迭代，JIT并不能优化获取数组长度的开销。
The first key is 21 bytes long (the byte length is shown in parentheses [()]) and is called GLOBALS/c_setprinter followed by a NULL, which is ASCII zero.
第一个键为21字节（字节长度显示在括号中 [()]），被称为GLOBALS/c_setprinter，后跟NULL，其为ASCII 码零。

In addition to comparing the length and index values for equality, you must also check for either a null Number after parsing or an empty input string (" "or length of zero).
除了要比较长度和索引值是否相等之外，还必须检查是解析后的nullNumber还是一个空的输入字符串(或长度为0)。
