Const is a key word in C + + language, but if used well, it can greatly improve the robustness of the code. In general, the use of const is still quite a lot of places, but mainly
Basic type
1. List of basic types
Copy Code code as follows:
Type length Description
BOOL 1 True/false, default false, cannot treat non 0 values as true (do not use numbers to represent True/false)
BYTE 1 uint8 Alias
Rune 4 Int32
1. Charc = ' \72 '; The \72 represents a character, 72 is a octal number, and represents the ASCII character ":".
2. In 10*a++, a multiplication is the first to be multiplied (the output problem of such operator precedence is often liked in the
1, const pointer if the const appears to the left of the "*", it means that the const modifier is pointing to the data, if it appears on the right, Note that the const modifier is the pointer, the constant pointer, which can no longer point to
One, const
1. In the definition of variable
(1) const int a=10;
Description: The defined int type variable A cannot be modified and can only be used. A variable with the Const keyword can be defined as a global variable, but at this point the global
C language initial contactThese days I have a preliminary understanding of the C language and read a lot of grammar knowledge.
# Include int main () {printf ("hello world \ n"); return 0 ;}
This is my first simple program design. I believe most
A constant is an identifier (first name) of a simple value. As the name implies, the value cannot be changed during script execution (except for the so-called magic constants, they are not constants). Changshime is considered to be case sensitive.
Break, Continue, ReadOnly, Const, Ref, and Out params, readonlyparams
I have studied basic things such as Break and Continue; ReadOnly and Const; ref, out, And params, but I have not carefully studied what the problem is. I recently used it in
A const member function, which can read the data members of a class, but cannot modify the data members of the class.1 statementAfter the parameter list declared by the member function, add the CONST keyword, declare it as a constant member function

The concept of const is a variable that contains values that cannot be modified.A constant expression is an expression that can be fully evaluated at compile-time. Therefore, constants cannot be initialized from values that are extracted from a
JavaScript compatibility has long been a major problem for Web developers. Many developers suffer day and night due to the differences between formal specifications, fact standards, and various implementations. To this end, we mainly summarize the

Have you ever encountered a variable declaration like int * (* fp1) (int) [10]; that puzzles you? This article will show you how to understand this complex C/C ++ statement step by step. We will start with a simple declaration that we can encounter

Proficient classes and objects
This article is based on the knowledge of classes and objects that you already know.
Dynamic Memory Allocation in the object:
If the memory is dynamically allocated to the object, the memory should be
Understanding C ++ Problems
1. Reference
Professional C ++ code is heavily referenced. The reference of C ++ is the alias of another variable. Changes to the reference will change the value of the variable pointed to by the reference. You can

The basic task of object-oriented is to describe the object and classify and summarize the object. The class type is
