Definition of Reflection: the ability to review metadata and collect type information about it, metadata (the edited basic data unit) is a large list of tables, the compiler creates a class definition table, a field definition table, a method

We found that design patterns are very popular in the Java community, but not so much in the C + + community, or even a bit of exclusion, what causes this difference. (1) C + + memory needs to be managed by itself, so some patterns are not easy to

The assert (assertion) macro in C is one of the best debugging tools that embedded software developers can use. Although assert is powerful, I rarely see it implemented, and in some cases where it is used, its implementation is either flawed or

Huffman tree, also known as the optimal binary tree, is a tree with the shortest length of the weighted path, which can be used to construct the optimal coding for information transmission and data compression, and is a widely used two-fork
