language. I found that some developers know very little about these things. In any case, the answer to this unsigned integer is "> 6 ". The reason is that when there are signed and unsigned types in the expression, all operands are automatically converted to the unsigned type. Therefore,-20 is a very large positive integer, so the result calculated by this expression is greater than 6. This is very important for embedded systems that should frequently use the unsigned data type. If you fail to
to answer this question, you will not be able to get the job.
13. Evaluate the following code snippet:
Unsigned int zero = 0;Unsigned int compzero = 0 xFFFF;/* 1's complement of zero */
For a 16-bit processor of the int type, the above Code is incorrect. It should be written as follows:
Unsigned int compzero = ~ 0;

embedded systems. How do you write an infinite loop in C?There are several solutions to this problem. My preferred solution is:
While (1)

Some programmers prefer the following solutions:
For (;;)

On a whim today and back to make up the list and tuples, first of all, the list of Kazakhstan, the list is actually the most commonly used in Python data type, not only often used is also very powerful, and the C language inside the array is similar, the list of course can also be added and modified, but I do not intend to use the way the dictionary to explain , I would like to explain the following list of commonly used methods just fine.1, first I f

Fully understand the dangers of "magic quotes" and SQL injection.I want to read that the developers here are already very familiar with SQL injection. But I'm still listing this here because it's a bit hard to understand.Magic quotation marks (Magic Quote) is a process that automatically escapes data into a PHP script. It is best to avoid escaping while encoding and escaping as needed at run
