Today, I would like to talk to you about how to use mobile objects instead of copy objects in Craft 11. Many people may not know much about it. In order to make you understand better, the editor summarized the following for you. I hope you can get something according to this article.

The string class is a very important class in the C++ standard library, which is very convenient to use. But there is a question.

Question: copy constructors and assignment operators generate copies of text columns whether they are needed or not.

The concepts of right value reference and movement are introduced in Category 11, which allows programmers to choose whether to copy or move objects when constructing and assigning values, thus greatly improving the efficiency of the program.

Example

The code uses the copy constructor of string, the copy version of the assignment operator, and the mobile version of the assignment operator to compare.

After reading the above, do you have any further understanding of how to use mobile class objects instead of copy class objects in Category 11? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
