Bitfield in C Language I. Bit domain When storing some information, it does not need to occupy a full byte, but only needs to occupy a few or one binary bit. For example, when storing a switch value, there are only two States: 0 and 1. Use one

Analysis of sizeof in C Language I. sizeof ConceptSizeof is a type of single object operator in C language, such as other operators ++ and -- in C language. It is not a function. The sizeof operator provides the storage size of its operands in bytes.

Sieve of Atkin is a fast prime number filtering algorithm, which is mature and simple. #include #include /* limit ← 1000000 */#define LIMIT(1000000)#define FALSE(0)#define TRUE(~FALSE)int main(int argc, char* argv[]){int sieve_list[LIMIT + 1];int n,

This article introduces a small tool written by the author. The simple code contains the C language's string processing skills, simple parsing of text files, and the Data Copying Method of binary files, format the output text file. The tool input is

I. Introduction The essence of a hook is a program used to process system messages. It is mounted to the system through system calls. There are many types of hooks. Each Hook can intercept and process the corresponding message. Each

#. String suggestion The convenience of using string is unnecessary. Here we should emphasize the security of string. String is not omnipotent. If you need to process strings frequently in a large project and may be multi-threaded, you must be

C ++ code optimization method summary Optimization is a very big topic. This article does not go deep into performance analysis theories and algorithm efficiency, and I do not have this capability. I just want to summarize some optimization

Introduction Because c-language strings are prone to errors and are difficult to manage, hackers may even use the possible buffer overflow bug to target c-language strings. Therefore, many character string encapsulation classes have emerged.

At the end of the 18th century, Gauss defined the so-called concept of coequal. This thing is almost everywhere in discrete mathematics and has many functions. In particular, many encryption algorithms are useful now. The same power is also based on

Rtti: runtime type information, which indicates the runtime type information. It provides a method for determining the object type during runtime.   The forced transformation of C-style is as follows: (T) exdivssion // cast exdivssion to be of type

Many strings may report errors when being copied using strcpy or garbled characters when being directly assigned values, because they are not initialized. Char * STR = (char *) malloc (sizeof (char )); Memset (STR, 0, sizeof (char ); Sometimes the

I have seen it in a forum before. It has been too long and I don't quite remember it. Today I turned it out and found it quite classic. I posted it. As follows: This is a typical problem that many people may encounter. This is also a problem that is
