Geek Youth's state machine, check table, pure C language realization1. The question was raised. AbstractBuild one, not just him, many people have discussed this problem with me: how to ensure that the needs of change, expansion of the situation. The

1. Functions of constructorsConstructors only perform initialization that has no practical meaning. Because most of the "meaningful" values of member variables are not determined in the constructor.If you can, use the init () method to set the

1. Const-Modified variablesA const-modified variable cannot be changed by assigning another value to the variable.　1 int main{2 Char buf[4]; 3 Const int 0; // A cannot be changed 4 ten; // 5View CodeThis is easier to

In C + + there is a copy constructor, and the copy constructor forms an overload with different constructors (which is important), which means that (either the class entry is a normal constructor or a copy constructor, not 2 will execute). OK,

See a topic, probably i=i++ or something like that.At first glance, it is easy to know that i++ first participates in the calculation and then increases itself,So I do not change.But a careful thought,If I do not change,So after the

I. OverviewC # 's type system is uniform, so any type of value can be handled by object. Each type in C # derives directly or indirectly from the object class type, and object is the final base class for all types. C # Data types fall into three

What do you mean, it's lightweight? Because it synchronizes only the shaping data (that is, the int type, the long line) .Use the following table specifically: Interlocked.Increment (ref value) Value plus one (atomic operation)
