1. Odd Number of Qiu Lambda calculus is equivalent to Turing. Lambda can be used to simulate natural numbers. The most common one is Qiu odd: 0= λ F. λ x. x1= λ F. λ x. f x2= λ F. λ x. F (f x)3= λ F. λ x. F (f (f x )) To put it simply, function

[Glossary] Reference counting: reference counting is a concept frequently used in modern memory management. Its basic idea is to reference a shared object at the same time by counting multiple different objects. Specifically, when an instance of an

Understand or be familiar with C ++ and have a certain understanding of function overloading. Function overloading in C ++ refers to declaring several function-like functions, but the parameter types or sequences of these functions must be different,

We have discussed how to encapsulate private instance members, public instance members, Private Static members, public static members, and static classes in JavaScript. This time we will discuss the other two elements of object-oriented programming:
