I am busy submitting versions before Christmas, and the encoding volume is greatly increased, with an average of 2,300 lines, sometimes thousands of lines. Code directly without design. Because it is related to some devices, output

The value type is stored in the stack and accessed directly. If there are: int a = 0; int B = a; an object in two stacks is generated.
The reference type must be explicitly allocated in the heap and cannot be accessed directly. A stack object (C ++

Recently, I heard from my colleagues that a company asked C ++ allocator related questions during an interview.
Allocator templates are essentially a set of memory management requirements of stl containers. They are called concept in generic
Previously, we introduced allocator of c ++. Since the c ++ standard library already has a standard implementation, why should we implement allocator on our own? For performance considerations, many programs implement their own allocator to avoid

Principle 16: do not create invalid objects.
To sum up, there are three points:
1. It still takes time to create and destroy heap objects.
For example

Volatile reminds the compiler that the variables defined after it may change at any time. Therefore, the compiled program will directly read data from the variable address every time it needs to store or read the variable. If there is no volatile
Summary of parameters passed between forms:
Solution 1: The form is a class. You can define global variables in the Form class. The type is public and static.
Example: public static string str = "";
Note that it is a static variable. If it
