The problem is this: the cat screamed, all the mice began to flee, the owner was awakened. Requirements: 1, must have the linkage sex, the mouse and the human behavior is passive 2, consider the expandable line, cat calls may cause other linkage effects See this program design topic, my first reaction is to use the event to solve, the cat called triggered the event, causing the mouse to escape, the mouse fled and triggered the incident caused the owner to be awakened. So according to this idea,

Call a colleague's function, pass in the goods_list, get the product information, and then match the product information with the Goods_list information to merge.But the colleague returned the data and changed the parameters I passed in, Goods_list. Equivalent to a parameter reference, that is, changing data at the same address in memory,Overwrite the parameter goods_list I passed in. Cause my parameters to

Requirement: The program prepares several QR codes for the public account. The total amount is RMB. scan the QR codes to receive the QR codes. each QR code must receive a red envelope. you cannot receive the QR codes again after receiving the QR codes, this is different from the normal scanning code to send a red envelope advertisement. there is only one QR code, and anyone can scan and spread it. the probl
