Recently learning data structure, the first touch feel good difficult, decadent a period of time, and then re-opened the study, suddenly feel a great interest. There are some new understandings of the use of these codes. Below is a brief talk about

When preparing for a test, you often encounter the question of how many bytes a data type of C + + occupies, and review the following information, summarized as follows:Let's start by listing the types of data in C + +:1, Shaping: int, long2,

Writes an exception to the log file, you can know which exceptions the program has occurred while debugging the program, and you can know where the exception occurred. This is especially effective for programs that need to be run long and debugged.1

In the. NET WinForm program, if the direct-start form is the main window, the main window cannot be closed because it maintains a Windows message loop,Once it is closed, it declares that the entire application ends, so the newly opened window is
