如何在算法上使用字符编码算法？ [英] How to use character encoding algorithm on the algorithm?

问题描述

您好，

下面的C代码将字符转换为7位编码：

Hello,
The C code below converts characters to 7bit encodings:

int n = 0;
unsigned char a = 0;
unsigned char b = 0;
while (read_byte(&byte))
{
    a |= (b >> (n + 2)) & (077 >> n);
    store_7bit(a);
    a = 0;
    a |= (b << (5 - n)) & ((077 << (5 - n)) & 077);
    if (n == 5)
    {
        store_7bit(a);
        a = 0;
    }
    n = (n + 2) % 7;
}

我的任务是使用该算法在C编程中动态地将字符转换为7位编码，但是不知道。

这是怎么做的？

I have been tasked to use the algorithm to convert characters to 7bit encodings on the fly in C programming, but have no idea.
How is this done?

推荐答案

只需更换

Just replace

while (read_byte(&byte)) {

使用循环遍历您的数据。



但在你做之前，我会测试那段代码，因为它目前对我来说看起来不太合适。它实际上并不使用您在...中读取的数据...

With a loop that runs through your data.

But before you do, I'd test that code, as it doesn't look like it works to me at present. It doesn't actually use the data you read in...
