This chapter describes the general introduction of containers, iterators, algorithms, and function simulation. It is a summary of chapter 6, 7, and 8.
1. (P74)
The basic concept of STL is to separate data from operations. Data is managed by container categories, and operations are defined by custom algorithms. The iterator acts as an adhesive between the two

1. Enumerations are a basic data type. Enumeration variables have a finite value, and enumeration elements are constants, not variables.
2. Enumeration variables are usually assigned by assignment statements, not by dynamic input. Enumeration elements can be defined by a system or user as a sequential value, but enumeration elements and integers are not the same, and they belong to different types. Therefore, you cannot use printf stat
Chapter 5. Relationship between arrays and pointers 1. array names can be considered as pointers. See the following example: Example 1: int array [10] = {,}, value; value = array [0]; // It can also be written: value = * array; value = array [3]; // It can also be written as: value = * (array + 3); value = array [4]; // It can also be written: value = * (array + 4); In the above example, the array name arra
