1. Lao Zhou thinks that they may understand the following situations:
2. 1. Get the hard disk, CPU serial number, and the MAC address of the network card, all converted to the string;
3. Other functions, no, usually three operators, very simple, the boss's price <= 650 ocean, he is unwilling to make 700 whole.
4, 2, how to do automatic packaging? Don't think about complexity, in fact, it is to control a relay. After the items read the weight on the electronic scale, first post into the database server to save;
5. Okay, write and write, it's almost the first day of the New Year, you can't write anymore, and then write it on New Year's Eve, you can only end.
6, 3, then wait for about 800 milliseconds. The rolling wheels of the conveyor belt will move. When the item reaches the place where the packaging bag is hung, a high level will be output on the production line;
7. Back to the first example
8. 6. Notify the re -examination time of the candidate, and the meeting is over.
9. The above players are impressed by Lao Zhou. The others are "ordinary people" similar to us.
10. So how can this error be changed? Very easy, just turn the _out parameter into a pointer to the pointer. Is it a baby?
11. Therefore, the correct code is like this:
12, 2, during the interview online, one person in charge of the company+Lao Zhou+candidates, three of them voice group chat;
13. 2, insert the pinyin of the customer's surname into the head of the string above, insert the pinyin of the customer's name to the end of the string above;
14, 3, the person in charge of the company first asked their company's unique questions;
15. 1. The company to be recruited will make the candidate's work experience and make the resume into a PDF file, and send it to Lao Zhou in advance. Lao Zhou is allowed to ask what questions;
16. So, the project Lao Zhou finally told them, giving up, not doing it, I can't get it.
17. After the initial test, the company will talk to Lao Zhou alone and exchange the evaluation of the applicants just now.
18, 5, the bag and the items were transmitted to the heating sealing bars together. At this time, the production line will be reset;
19、
20, 1. Electronic scale module, the serial port is directly output data, and it is over when reading;
21, 5. Return to the person in charge of the company and ask the candidate to ask questions freely. He answered questions (non -programming);
22、
23, July, and August, Lao Zhou was dispatched to another company to work to help them repair the "Eight Brother". This Lao Zhou mentioned in the blog post.
24, 7. After the mouth is sealed, the relay will be automatically powered off, and the high level will be restored. After the upper program reads the high level, the seal is completed, ends, enter the next cycle, and wait for new items to come over.
25. When registering verification, it is also calculated according to the above process to see if the results are equal. The registered file is encrypted with a certificate generated by itself, and it is OK to store it in the directory where the procedure is located.
26, 5, and then turning the above Byte array into a Base64 string, which is the registration code.
27. Before the Mid -Autumn Festival, there is a project that must pass the electronic scales to record the weight of the item, and then open the automatic packaging of the packaging machine. Don't listen to this project, you are so simple to jump off the building. Lao Zhou can talk about the principle:
28, 4, Lao Zhou asked the level of the candidate;
29, 4, in the Byte array obtained by 3, the index 0, 4, 8, 12, 16, 20, 24, 28 is inserted into fixed bytes, and the Byte array of 40 elements is obtained;
30, 3, make three SHA256 operations obtained from 2 to get the Byte array;
31, 6. After the upper program receives the reset signal, send a low level to the relay, connect the power supply, start heating.
