问题描述
请找到以下代码段.
unsigned char bInput[20];
unsigned char cInput[20];
从一个函数中，我在bInput中获取一个二进制数据，并使用strlen(bInput)确定了它的长度.我将二进制形式的bInput转换为ASCII，并存储在cInput中，并打印了其长度.但是两者是不同的.
From a function, I get a binary data in bInput and I determined its length using strlen(bInput).I converted bInput which is in binary to ASCII and stored in cInput and printed its length. But both are different.
我是编程新手.请对其行为进行指导.
I am new to programming. Please guide regarding its behaviour.
推荐答案
结果在两种情况下都不相同.以下是一个示例方案:Null是有效的UTF-8，仅对C'strings'无效.
result wont be same for both cases.Below is one sample scenario:Null is valid UTF-8, it just doesn't work with C 'strings'.
char temp[8];
buf = "abcde\0f";
这里有一个长度为8的缓冲区，其中包含以下char值:
What we have here is a buffer of length 8, which contains these char values:
97 98 99 100 101 0 102 0
在这里，按照strlen设计，strlen(temp)等于5，但是，缓冲区的实际长度是8.
here,strlen(temp) is equal to 5 as per strlen design,however,The actual length of the buffer is eight.
