In Windows, when writing programs with file operations, you may encounter a strange phenomenon. In the process of reading a file in text format, the feof () function is unexpectedly true before the end of the file. This is surprising, and it is hard

In the integrated development environment of Windows (the problem exists in Qt, VC, vs), write about the file read C/E + + program, the occurrence of the unexpected termination when reading to 0X1A, after the debug check found that 0x1a after

The undo mechanism is a clever feature of Oracle and one of the difficulties in learning oracle. Next we will learn more about it internally. Session 1: Scott user, initiates a transaction hr@ORCL> conn scott/oracleConnected.scott@ORCL> UPDATE emp

Associating processes and ports is a very useful function. You can clearly know which programs are using which ports are helpful for trojan detection and removal. However, although we can use the task manager to browse the process list and use

We often think that the code we write is okay and we don't need to test it. In the past, I thought that testing is a waste of time, so I didn't study it carefully. Recently, I was eager to try unit testing. Combining my previous programming

Overall, Python itself does not support binary, but it provides a module to compensate for it, which is the struct module. Python does not have a binary type, but it can store binary types of data, that is, using string string types to store

Sometimes it is necessary to use Python to process binary data, for example, access to files, socket operation. At this point, you can use the Python struct module to do this. Structs can be used to manipulate structures in C. The three most
