If you include a precision specifier for a string output (such as "%.10s"), then you can protect against buffer overflows by specifying the maximum length of the output.
如果指定字符串输出的精确指定符(比如%. 10s)，那么您就能够通过指定输出的最大长度来防止缓冲区溢出。
You can even use "*" as a precision specifier (such as "%.*s"), so you can pass in a maximum length instead of having the maximum length embedded in the control string.
甚至可以使用“ * ”作为精确指定符（比如“ %.*s ”），这样您就可以传入一个最大长度值，而不是在控制字符串中嵌入最大长度值。
