Why is the char type in the following range? In C, the signed char type ranges from-128 ~ 127. This is also written in every textbook, but no book (including teachers) will give you why-128 ~ 127. It seems that this problem is easy and easy, so you don't have to think about why. Isn't there a formula with an Integer Range:-2 ^ (n-1 )~ 2 ^ (n-1)-1 (n is the number of digits occupied by the memory of the inte

OpenSSL symmetric encryption algorithm commands 1. symmetric encryption algorithm Overview The openssl Encryption Algorithm Library provides a wide range of symmetric encryption algorithms. We can use the symmetric encryption algorithm commands provided by openssl, or call the APIS provided by openssl. Openssl symmetric encryption algorithm commands are mainly used to encrypt and decrypt data. openssl provides instructions for all supported symmetric encryption algorithms, the names of these app

[Unicode] character encoding table information, unicode character encoding The UTF-8 is somewhat similar to the Haffman encoding, which encodes Unicode: 0x00-0x7F characters, expressed in a single byte; The character 0x80-0x7FF is expressed in two bytes; 0x800-0xFFFF characters are represented in 3 bytes; ① The unicode range of a number is 0x0030 ~ Zero x 0039 ② The unicode range of English letters is: Uppercase letters A to Z (Latin letters): 0x0041 ~ 0x005A Lowercase letters a to z (Latin lett

Then we can first simple design ISO8583, define 128 fields, all can be considered similar to the above mentioned "account number" and other financial data types, in one order, corresponding to 128 fields in one field. Each data type occupies a fixed length, and this order and length are defined beforehand. This is simple,

Big talk command-ss, big talk-ss Big talk command-ss Ss is short for Socket Statistics. As the name suggests, the ss command can be used to obtain socket statistics, which can display content similar to netstat. Advantages: (1) display more detailed information about TCP and connection status, (2) faster and more efficient than netstat. 1 format Format: ss [option]… [Filter] Netstat traverses proc to obtain socket information. ss uses netlink to communicate with the kernel tcp_diag module to obt

beginners "vulgar solution" one time. Or to say the replacement principle: (do not say no AH!) ） PS Help in the following points on the replacement map. Note: [] is added by the author. What foreigners translate is hard to understand. 1. The "permutation" filter uses the color values in the displacement chart [in fact, by the specified channel's grayscale value] to change the selection [pixel movement]-0 is the maximum negative change value, 255 is the largest Positive change value, gray value

, etc., all the data that can be summarized up to about 100 pieces of data. First, we can simply design iso8583, define 128 fields, and sort all financial data types that can be considered, such as the "Account" mentioned above, in one order, corresponds to one of the 128 fields. Each data type occupies a fixed length, which is defined in advance. This is simple. When you want to send a packet, connect the

The meaning of ctrl+c,ctrl+d,ctrl+z in Linux Both Ctrl + C and ctrl+z are breaking orders, but their role is different. CTRL + C is the execution of a forced interrupt program. The ctrl+z is to break the task, but the task is not over, he is still in the process he just maintains a pending state.
