signed int

Today, we are analyzing the Code Implementation of the string operation class in the redis source code. With several analysis experiences, I gradually felt that I had to change the analysis method. If every API performs code analysis and some

After reading relevant materials and understanding, I will summarize the bit domains in C language. I have not said much about the definition of bit domains here, here I will summarize the system where there is ambiguity in the counterpoint domain.

Environment: Dev-C ++ 4.9.6.0 (GCC/mingw32), use the-wall compilation Option The basic types include char, Int, and float/double ).When defining basic type variables, you can use the symbol attributes signed, unsigned (for char, INT), and length

Recently, when I was writing a program, I accidentally encountered an error. After careful consideration and debugging, I confirmed that the error was due to the unsigned type. Baidu has summarized it for a long time.   I believe many people know

For ix86 programming, sometimes it is necessary to change from the real mode to the protection mode (for example, to access extended memory in the DOS era, or to write pilot code, of course, if you program in a 32-bit operating system, you won't be

Various data types in C language and the bytes and value range in the system The C language contains five basic data types: void, Int, float, double, and char.(C ++ defines the other two basic data types: bool and wchar_t.Some basic data

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 binary digit. To save storage space and
