The full name of cmme is Capability Maturity Model integration, that is, the Software Capability Maturity Model integration model. There are 5 levels and 25 process areas (PA ).

I got a training about the cmme from colleague in the team meeting at yestoday. I heared the cmme long time ago, but it is the first time start to learn it. what's the cmme? The offiical definition is Capability Maturity Model Integration . It is a

Cmme ,
Impression There are three profound terms: Commitment, quantification, and goal. From these three words, I have a simple idea about a question that everyone is asking. The question is: why some of them have implemented cmmi4
The predecessor of the cmme model is SW-CMM and SE-CMM, the former is what we refer to CMM. The main difference between cmme and SW-CMM is that it covers many fields; so far it includes four areas:

#define是C语言中提供的宏定义命令, the main purpose is to provide programmers with certain convenience in programming, and to a certain extent, improve the efficiency of the program, but students often do not understand the nature of the command in learning, always create some confusion here, in the programming of the misuse of the command, To make the program run inconsistent with the intended purpose, or to read the program written by others, the results of the
There are many places in the C language where macro definitions are used, such as in header files to prevent header files from being repeatedly included:
#ifndef ctest_header_h
#define CTEST_HEADER_H
/header file content
#endif
Many macro definitions are also available in our common stdio.h header files, such as:
#define BUFSIZ 1024//Buffer size
#define EOF ( -1

The use of a typedef
In C/s + + language, a typedef is commonly used to define an identifier and a keyword alias, which is part of the language compilation process, but it does not actually allocate memory space, as in the case of:
typedef int INT;typedef int ARRAY[10];typedef (int*) pint;
A typedef enhances the readability of the program, as well as the flexibility of the identifier, but it also has drawbacks such as "not intuitive".
Second, #
# Define is a macro definition Command provided in C language. Its main purpose is to provide programmers with some convenience in programming and improve the program running efficiency to a certain extent, however, students often cannotUnderstanding the essence of this command always creates some confusion here. This command is misused during programming to make the program run differently from the expected purpose, or when reading a program written
. Let's take a closer look at the msdn example and have a good understanding.
The following is an example of how to define a Unified Version macro.
Assume that the project contains the resource script file resource. RC, and the unique version number is stored in define. h. Other CPP files that require version numbers contain this file.
Let's take a look at define
The examples in this article describe how classes are defined in JavaScript. Share to everyone for your reference, specific as follows:
JavaScript itself does not support object-oriented, it does not have an access control character, it does not define the class's keyword class, it does not support inherited extend or colons, nor does it support virtual functions, but JavaScript is a flexible language, Let's take a look at how JavaScript, without the
For a long time, macro definition # define is used to define some simple constants. At most, it is used to define a function. It seldom pays attention to macro definition usage. Until the following code is displayed:

#defineThe command #define defines an identifier and a string. Each time the identifier is encountered in the source program, it is substituted with a defined string. The ANSI standard defines an identifier as a macro name and replaces the process with a macro substitution. The general form of the command is:
#define Identifier string

It does not mean that it is correct or not, possible errors are detected and reported only when the expanded source program is compiled. For example:# Define PI 3.1415926In the program: Area = pI * r will be replaced with
