role, but not the private permissions. The inherited public permissions are still public permissions. Definition 4: Generally, inheritance defines a binary relationship between R and R. If NIAR × R is a set of general inheritance relationships, then (r1, r2) rr2. If r1 → r2, then for Ⅱ p, CP (r1), there is p, CP (r2 ). Unlike General inheritance, extended inheritance not only inherits public permissions, but also private permissions. The inherited permission attributes remain unchanged. Definit

C + + references-temporary variables, reference parameters, and const referencesIf the actual participation reference parameter does not match, C + + generates a temporary variable. If the reference parameter is const, the compiler generates a temporary variable in the following two scenarios:The argument type is correct, but not an lvalueThe argument type is incorrect, but can be converted to the correct typeLvalue parameters are data objects that can be referenced, for example, variables, arra

article to describe the use of random numbers in Visual C #.. Net. Frameword provides a class system.random that generates random numbers, which are imported by default and can be used directly during programming. We know that the computer does not produce a completely random number, the resulting number is called a pseudo-random number, it is the same probability from a limited set of numbers, the selected number is not completely random, but in practical terms, its randomness is sufficient.We

DOTNET. frameword provides a special random generation class system. random, a computer cannot generate completely random numbers. The numbers it generates are called pseudo-random numbers. They are selected from a group of finite numbers with the same probability, the selected number is not random, but its degree of randomness is sufficient. When using a random number, you must first initialize a random number generator. There are two methods; The first method does not specify a random seed.
