1, container = data structure + algorithm. It is equivalent to designing something that is designed to hold that data for complex data. Used to transfer complex data in development. 2, the template function can only be written in the header file. Statements cannot be made alone. 3, STL container classes are divided into three categories: (1), the sequence of container class vector array. The query is fast, but the insertion is slow. The order of data added is related to the size. An array of

I have been using thinksns for a month. I was worried that I would encounter problems when upgrading the code. so I took notes and did not expect many questions. I also asked many people in the community, therefore, I am a lazy person and have a rough description. if you have any questions,
interaction of various roles will become more and more complex, we need to have a visual method to let different roles clearly know what they are doing with other people's relationship, here Kanban is the best way. The above lists some of the key features of the electronic Kanban in TFS, but there is always an advantage between the electronic tool and the physical tool, and it is recommended that the team use it as appropriate.Coding flow in the development process is a critical process that af

Some time ago, when the younger brother reviewed, he copied some sentences that he thought would be helpful to understanding the Management Code. This post is here, hoping to help anyone who needs it. These replicas are mainly for the definition of managed code and the advantages and disadvantages of managed code and unmanaged code. They also mention how it works in CLR.
Statement in advance: these transcripts (definitions) are mainly from the following books (articles)

JQuery Introduction
Disadvantages of common JavaScript: different controls are operated in different ways, and different browsers are different. It is very troublesome to write cross-browser programs. Therefore, many JavaScript encapsulation libraries, such as Prototype, Dojo, ExtJS, and JQuery, are generated. These lib
language, all the program code looks mysterious and unsolvable. Before learning about this language, you cannot even see obvious syntax errors.
In the first stage of learning, you will start to find something we usually call programming style. So you begin to pay attention to program code that does not follow the contraction standard and variables that use multiple uppercase letters.
At this stage, you will say, "Damn bastard, here we are.YesWe need
