The DES algorithm is called Data Encryption Standard, which was published by IBM in 1975. The DES algorithm has three entry parameters:Key, Data, Mode. Among them, the Key is 8 bytes in 64-bit, which is the Key of the DES algorithm; Data is also 8

When I was in a company, it looked very bad, that is, the state of an object is represented by Int. Personal perception mainly has the following shortcomings. Advantages of enumeration: 1. Although int is a strong type in C #, Int Is not a strong

VBA language basics Id 1I. DefinitionAn identifier is a symbol that identifies the unit of a variable, constant, process, function, class, and other languages. It can be used to reference variables, constants, processes, functions, and classes.Ii.

When I first went to the company for a written test a few days ago, I ran into several bitwise operations. I was just reading C ++ primer and happened to see bitwise operations. So I went online to search for the next article. Article To study it!

The logical (Boolean) operator is used to calculate the expression of the result of the boolean type. The result of the operation is boolean type. The calculation result is as follows: Operator Operation Example Result

Our practice is usually (especially in the learning phase): to define a new variable and use it for exchange. The Code is as follows: int A, B; A = 10; B = 15; Int T; T = A; A = B; B = T; This algorithm is easy to understand and is especially
