Program flow and C code implementation for removing repeated rows from source files I. Requirement DescriptionDeduplication is required for a file (source file) that contains several lines of records with the same records, and records after deduplication are written to another file (target file). That is, there are no two rows of records with the same content in the last generated file. If there is a blank

that the code to add the new data is not executed. However, due to the existence of a transaction, an exception in the middle will cause the failure of the transaction, when the old data should be deleted. Best practices for upgrading a database before we learned how to upgrade the database is very rude, in order to ensure that the database table is up-to-date, we simply removed the current table in the Onupgrade () method, and then forced to re-ex

, we introduce the function of explode (), which is a string processing function, which is used to decompose the specific usage of the string, for example: Decompose the numbers in the 0:1:2:3:4″ $val = "0:1:2:3:4";$rid =explode (":", $val); After the explode () function is processed, all the numbers within the $val are decomposed into $rid arrays, which are printed only when they are referenced: echo "$rid [0], $rid [1], $rid [2] ..."; . The explode () function plays a very important role

I have worked hard in the C ++ world for more than a year. I have not seen much code, but I have seen a lot of bad code. This is not to belittle others, but to feel that you must have a professional attitude towards everything. The code I see has the following major issues: 1. the program does not talk about structure

directory of the source code. 3. Run make 4. If no exception occurs, several DLL and exe files will be generated in the src directory, and all the files will be copied to other directories, such as C:/line. 5. Find cygwin1.dll and cyggcc_s-1.dll files from cygwin's installation directory and copy them to your directory. 6. Find the old Linux program and Library (make sure there is no nptl, and I ha
