Like most relational databases, log files are an important part of the MySQL database. MySQL has several different log files, usually including error log files, binary logs, generic logs, slow query logs, and so on. These logs can help us locate
Problem:For a 4-byte unsigned integer variable, the binary value indicates the number of "1" and the algorithm execution efficiency is as high as possible. Solution 1 (bitwise traversal): Use the bitwise operation to determine whether 1 exists after
Both int and float are 4-byte, 32-bit representations. Why is the range of float greater than int?Float precision is 6~7 bit. 1.66*10^10 's numerical results are not 166 0000 0000, the larger the error.These problems are caused by the way
A description of the number of 1 in binary system For a variable of one byte (8bit), the number of "1" in the second binary representation requires the algorithm to be executed as high as possible."Solution One"You can give a eight-bit binary

Why do we need octal and hexadecimal?
In programming, we usually use 10 hexadecimal notation ...... C/C ++ is a high-level language.
For example:
Int A = 100, B = 99;
However, because the representation of data in a computer exists in
